0393543E7A594A71FCD3FB1CDB21F96C.taxon	discussion	Observations / Discussion: This species is mostly reminiscent of pale specimens of the much more common and variable C. catharinae (and C. albolutescens, C. pseudoparvus and C. pallens) if accepted as separate taxa). C. albertii is, however, paler, and we have never observed any initial yellow colouration of the pileus, though a brownish (yellowish) discolouration with age is normal. The spores of C. catharinae are slightly smaller (Figs 2 H and 3 A), but differences are vague and it should only be used as a supportive character. The likewise pale C. parvus was described without any significant alkaline reaction on surfaces (Henry 1935). The epithet parvus has been applied for various taxa in this group, but the original description states a strong alkaline reaction of the context ̅ a character exhibited by no species in the calochroid group. It is, however, possible that it covers pale specimens of C. dibaphus or C. arcuatorum. C. albertii is the only calochroid taxon from deciduous forests that combines almost entirely pale fruit bodies with a positive alkaline reaction on both pileus and bulbipellis. Clear violaceous tinged lamellae have only been observed in one French collection. We have only encountered the species a few times, but it seems to be rare in Northern Europe, but more common in southern Europe. It may have been collected as C. parvus, C. catharinae, C. pallens, C. pseudoparvus and C. albolutescens. The species is named after the Hungarian mycologist, László Albert, who has been working with this genus for more than 20 years, and also found the hungarian collection. An ITS sequence from the holotype of C. albertii is available at GenBank (accession DQ 323958).	en	Frøslev, Tobias G., Jeppesen, Thomas S., Laessøe, Thomas (2006): Seven new calochroid and fulvoid species of Cortinarius.

0393543E7A584A71FF72F900D9E9F949.taxon	discussion	Observations / Discussion: C. chailluzii is recognised by the bright yellow pileus margin, which contrasts the brown centre, recalling the oxidation seen in several fulvoid species, and distinguishing it from C. cisticola, which has a more uniformly coloured pileus. Other similar species have either a negative reaction (C. calochrous, C. ochraceopallescens etc.) or an intense pink KOH reaction (C. catharinae) on the bulbipellis. Microscopically, it occupies an intermediate position (Figs 2 and 3 B), and with the limited knowledge of its variation it might be difficult to separate from several others on microscopy alone. Presently, we only know this species from two collections including the type. The collection published under the name C. caroli in Consiglio et al. (2004) has an identical ITS sequence and morphology and represents the second record of this species. (For a discussion of the binomial C. caroli see the discussion under C. cisticola.) The species is named after the forest where we first found it, Forêt du Chailluz, in Doubs, France. As we have only encountered the species once ourselves among many hundred collections of calochroid species, it seems probable that the species is very rare in the investigated area. An ITS sequence from the holotype of C. chailluzii is available at GenBank (accession DQ 323962).	en	Frøslev, Tobias G., Jeppesen, Thomas S., Laessøe, Thomas (2006): Seven new calochroid and fulvoid species of Cortinarius.

0393543E7A584A72FCC0F901DEB8FCD0.taxon	discussion	Observations / Discussion: Apparently C. cisticola is able to form mycorrhiza with species of Cistaceae. We have found it in semi-open Mediterranean maqui on calcareous ground associated with Cistus spp. and in Northern Europe on alvar in association with Helianthemum nummularium. We have collected it once in a nemoral forest with Fagus sylvatica in Denmark, and it is known from Quercus-Corylus forest in Sweden. C. cisticola is recognised by the yellow pileus with whitish to brownish veil patches (not small scales) in combination with pale, violaceous lamellae, a white stipe and possibly also the ecology (if collected with cistaceous plants). Furthermore, it has a narrower, not distinctly flattened bulb, compared with similar species, which seems to be a useful diagnostic character. Considering the almost uniformly yellow pileus, C. cisticola is most likely to be confused with C. calochrous or C. sublilacinopes, but both these differ by a more intense yellow cap colour, wider and more flattened bulbs, distinct yellow universal veil remnants at the bulb margin, smaller spores (see Figs 2 and 3 B), and also often by having small, dark brown velar scales on the pileus. Normally, the most yellow variants of C. platypus also differ by a larger (wider) and more flattened bulb. Considering the indistinct appearance, it is possible that the species is not rare in suitable habitats, and simply may have been treated as C. calochrous sensu lato. We have, however, only found it twice with certainty in Scandinavia. Brandrud et al. (1989 – 1998) applied the name C. calochrous ssp. calochrous var. caroli for the species. The original description of Phlegmacium caroli (Velenovsky 1920) is, however, insufficient to unambiguously apply to any of the presently recognized calochroid species. The type locality, Karlstejn near Prague in the Czech Republic, is very rich in calochroid Phlegmacium species that comply with the protologue. We found, for example, C. catharinae, C. sublilacinopes and C. ochraceopallescens there. Furthermore, no type was deposited, and as there exists no consensus usage of this name, the name is best treated as a nomen dubium. An ITS sequence from the holotype of C. cisticola is available at GenBank (accession DQ 323963).	en	Frøslev, Tobias G., Jeppesen, Thomas S., Laessøe, Thomas (2006): Seven new calochroid and fulvoid species of Cortinarius.

0393543E7A5B4A73FCD3FC8DDE05FC93.taxon	description	Pileus 60 – 120 (– 140) mm, hemispherical then plano-convex, glutinous, glabrous, with age slightly innately fibrillose, at first yellow (2 A 4 – 2 A 5 – 3 A 4 – 3 A 5 – 4 A 6), soon becoming ochre – yellow (4 B 6 – 4 B 7) then brownish (4 C 7 – 5 D 7), margin remains yellow (3 A 4 – 3 A 5), often with veil remnants seen as pale greenish yellow to whitish patches, or sometimes as small brownish scales, where damaged often more or less saffron-coloured to red brown (7 E 7). Lamellae emarginate, greyish white to cream when young. Stipe 50 – 120 X 10 – 25 mm with a broad marginate bulb (– 45 mm), whitish. Bulbipellis and mycelium characteristically pale cream yellow to bright greenish yellow (1 A 3 – 1 A 4), bulb margin often bright greenish yellow from veil remnants. Cortina whitish to greenish yellow, fairly abundant. Veil pale greenish yellow to white. Context whitish, sometimes with a very pale greyish brown tinge in stipe apex, a thin greenish yellow line is seen in the lower bulb cortex when the bulbipellis is strongly coloured. Taste mild, indistinct, smell somewhat yeast-like (like many phlegmacioid species, e. g. C. saporatus), sometimes with a faint curry component.

0393543E7A5B4A73FCD3FC8DDE05FC93.taxon	discussion	Observations / Discussion: Cortinarius langeorum is distinguished from all other fulvoid (and calochroid) species by the lack of yellow colour on lamellae, context and stipe, a rather strong alkaline reaction on the pileus in combination with the characteristic yellow veil (seen as remnants on the bulb margin) and a pale greenish yellow bulbipellis. It is most similar to the less pigment rich fulvoid species ̅ i. e. C. humolens (syn. C. claroflavus sensu Moser) and C. sulphurinus. The most similar species, C. humolens, differs in several respects. C. humolens has an earth-like smell, whereas C. langeorum has a neutral Phlegmacium- like smell, sometimes with a faint curry-like component. C. humolens has a weak alkaline reaction (negative to pale brownish) on the pileus, whereas C. langeorum reacts strongly brown to red – brown. Furthermore, C. humolens has yellowish colours on both lamellae and usually also on the stipe, where C. langeorum has colourless lamellae and stipe contrasting the yellow bulbipellis and veil remnants on the bulb margin. C. sulphurinus differs by the parsley-like smell, greenish yellow colours on the lamellae, stipe and context, and has a strong red alkaline reaction on the mycelial strands. C. flavovirens also has weak colours on the lamellae and in the context, but has a strong farinose smell and much smaller spores. Seen from above the pileus of C. langeorum oxidises in a way that makes it resemble more pigment-rich species (e. g. C. alcalinophilus, C. olearioides), which all, however, have yellow context and lamellae. Due to the lack of colours in the context and lamellae, it seems possible that the species could have been treated in the section Multiformes or Calochroi – but no names published in these sections fit the species to our knowledge. Aberrant specimens of C. caesiocortinatus may show a certain resemblance, but are easily identified by the (sub-) globose spores. The illustration of C. sulphurinus in Flora Agaricina Danica (Lange 1938) shows an expanded fruit body with brownish yellow colours on a pileus with velar patches. The original description of C. sulphurinus presents a more pigment rich species than the one collected and illustrated by Lange. Presently C. sulphurinus sensu Lange is widely perceived as a synonym of C. saporatus sensu Brandrud et al. (Brandrud et al. 1989 – 1998) syn. C. subturbinatus. This interpretation, however, has to be rejected as the drawing of Lange clearly shows an agaric with bright yellow colours on the bulb. In the many years after Lange drew his plate C. saporatus has never been found on or near the locality of C. sulphurinus sensu Lange. Contrarily, C. langeorum has one of its localities there. Therefore, as both the macroscopic and microscopic features fits well with C. langeorum, we dare to postulate that C. sulphurinus sensu Lange has found its final interpretation. It has only been found in localities hosting several other rare species of phlegmacioid Cortinarius, and seems to be among the top ten rarest phlegmacioid species in Denmark. Although the species is well known to us and easily recognisable, we have never encountered the species in southern parts of Europe or with other hosts than Fagus sylvatica, nor in the literature. We have chosen to name our species after the family Lange, which has given us three generations of prominent figures in mycology, and especially as an appreciation of Jakob E. Lange’s monumental work on agarics. The species was included in the study of Frøslev et al. (2005) as C. neolangei ined. (TF 2000 - 012, TSJ 2003 - 078 and TSJ 2003 - 057).

0393543E7A5A4A7CFCC0FC44DB18F97C.taxon	discussion	Observations / Discussion: Cortinarius sancti-felicis is recognised by the combination of an olivaceous grey pileus with a brownish alkaline reaction, the (brownish) velar scales, the strongly violaceous lamellae and large spores. It could be confused with atypical collections of C. parasuaveolens lacking the blue colours on the pileus, and therefore showing a weaker alkaline reaction on the pileus than usual. We have found such collections of C. parasuaveolens in Quercus pubescens forests in central Europe, but they had a thin violaceous line just below the pileipellis in section, not seen in C. sancti-felicis, greyish lamellae with only a weak violaceous tinge on the edge, and smaller spores. Generally the violaceous colours of C. sancti-felicis (both stipe and lamellae) are more reddish violet than those of C. parasuaveolens. Two more species known to us (i. e. C. insignibulbus and C. selandicus) have the combination of a strong pink alkaline reaction on the bulbipellis and a negative (to brownish) reaction on the pileipellis. C. insignibulbus is smaller with a paler pileus. C. selandicus has a paler pileus, sometimes with pale to violaceous veil patches (not small scales), paler lamellae, and so far it has only been recorded from nemoral Fagus sylvatica forests. These two species and C. parasuaveolens furthermore have smaller spores than C. sancti-felicis (Fig 3 C). C. vesterholtii has a brownish pileus, somewhat similar to mature fruit bodies of C. sancti-felicis, but has a negative alkaline reaction on the bulbipellis. C. sancti-felicis is named after the abbey, L’Abbaye Saint Félix de Montceau, situated at the summit of the mountain range, Massif de la Gardiole in Hérault, France, where the type was collected. The species was included in the study of Frøslev et al. (2005) as C. cf. calochrous 1 (TSJ 2002 - 072).

0393543E7A554A7DFF86F979D8E2FDE0.taxon	discussion	Observations / Discussion: The general impression of Cortinarius selandicus is an initially pale and later olivaceous brown, calochroid species with a clear difference in alkaline reactions between pileus and bulb, and often with weak pink to violaceous tinges on the cap and bulb. The disparity in alkaline reactions is also seen in C. sancti-felicis, which, however, has a pileus with brown spot like veil remnants and larger spores, and C. insignibulbus, which differ by a more persistently pale pileus (sometimes having small spot-like velar scales) and a more distinctly violaceous stipe. A positive reaction on the bulbipellis is seen in several other species, which, however, also show a positive reaction on the pileus and furthermore have paler or more yellowish pileal colours. Most similar might be pale specimens of C. nymphicolor, which have longer spores, and a pink reaction with KOH on the pileus. The olivaceous appearance in combination with the, however, rare and insignificant violaceous colours sometimes observed on the pileus and bulb, may recall C. lilacinovelatus, which, however, has a negative alkaline reaction on the bulbipellis. The colour reaction on the bulbipellis is of the same level (very pink) as e. g. C. catharinae, but often has a slower onset, and is only consistent on the most soft, white and fresh parts of the bulbipellis. The diagnostic characters have only recently become known to us, and as these characters have rarely been recorded in a sufficient way to allow us to determine collections from literature and other sources, we have difficulties in assessing the true distribution and rarity of this species. The species is named after the Danish island, Sjaelland, which hosts the largest known population of the species. An ITS sequence from the holotype of C. selandicus is available at GenBank (accession DQ 323978).	en	Frøslev, Tobias G., Jeppesen, Thomas S., Laessøe, Thomas (2006): Seven new calochroid and fulvoid species of Cortinarius.

0393543E7A544A7DFF72FDDAD98AF970.taxon	description	Pileus 50 – 80 mm, hemispherical then plano-convex, glabrous, glutinous, uniformly pale to darker brown (̿ 4 B 5 to 4 C 7 – 6 D 6), margin paler cream – brown to yellow – brown, sometimes with pale to violaceous universal veil remnants especially on margin. Lamellae emarginate, pale violaceous (15 – 17 A 2 to paler). Stipe 35 – 55 X 10 – 15 mm with an often not so wide bulb (– 25 mm), often intensely violaceous (17 – 18 A 3 – 19 A 4), but often paler (̿ 17 A 2). The colour is very consistent and persistent, though it fades from below with age and often discolours brownish. Bulb often sharply marginate, though not so wide, bulbipellis and mycelial strands whitish, bulb margin on younger specimens sometimes with remnants of violaceous veil. Cortina violaceous. Veil pale to faintly violaceus. Context whitish, in stipe cortex violaceous. Taste mild, smell indistinct. Spores amygdaliform to citriform with broad long apex, with distinct coarse ornament, relatively dark in the microscope, 10 – 11 X 5.5 – 6.5 µm, average 10.4 ± 0.4 X 6.1 ± 0.3 µm; Q ¼ 1.72 ± 0.08. Chemical reactions: KOH on pileipellis almost negative to brownish (6 F 7) but not red, on bulbipellis negative, in context negative or weak rose.	en	Frøslev, Tobias G., Jeppesen, Thomas S., Laessøe, Thomas (2006): Seven new calochroid and fulvoid species of Cortinarius.

0393543E7A544A7DFF72FDDAD98AF970.taxon	discussion	Observations / Discussion: Among calochroid taxa, C. vesterholtii is easily recognised by the brown pileus colours, the violet stipe, and the negative alkaline reaction on the bulbipellis. Similar species have lighter or livelier colours on the pileus, and / or a pink alkaline reaction on the bulbipellis. The most obvious possibility of misidentification is discoloured specimens of C. sodagnitus and possibly C. parasuaveolens, both having positive alkaline reactions. Furthermore, C. vesterholtii has some morphological affinities to distantly related non-calochroid species such as C. purpurascens, which differ by the typical purple staining reaction of species in that group. Superficial resemblance with brownish stained specimens belonging to the C. coerulescens group is also a possibility. These, however, have spores without a net-like ornamentation, and have a well-differentiated hypodermal layer, not seen in any calochroid taxa, and pronounced innate fibrils in the pileus. Furthermore, the violaceous colours of the stipe and lamellae of these species are more bluish than in C. vesterholtii. The species has been treated under the name C. provencalis (e. g. Bidaud et al. 2001, Moser 1997). Moser’s concept of C. provencalis included (discoloured) collections of C. sodagnitus along with the present species. The collection published in Moser & Jülich (1985 – 1999) as C. coeruleoochrascens almost certainly represents C. vesterholtii, a collection Moser referred to when describing C. provencalis (Moser 1997). The type of C. provencalis, however, represents a collection of C. sodagnitus (Frøslev et al., unpublished) leaving C. provencalis a synonym of C. sodagnitus. This also explains the larger variability of alkaline reactions and some morphological characters in the protologue of C. provencalis compared with the variability observed in C. sodagnitus and C. vesterholtii, respectively. The species is named after the Danish mycologist, Jan Vesterholt, who urged us to continue our study of this interesting group of Cortinarius. We have seen several photographs and references to this species (as C. provencalis) from the Mediterranean area, and it is most likely widespread, but not common in this area, whereas the species seems to be very rare in Northern Europe. An ITS sequence from the holotype of C. vesterholtii is available at GenBank (accession DQ 350842).	en	Frøslev, Tobias G., Jeppesen, Thomas S., Laessøe, Thomas (2006): Seven new calochroid and fulvoid species of Cortinarius.
