522A16765A091014FF50FF6BFD02FBDC.taxon	description	Description: — Lichenicolous fungus. Thallus inapparent, inhabiting the thallus of Tephromela atra, which darkens and is apparently damaged due to the infection (Fig 2 A). Apothecia black, shining, c. 0.2 – 0.4 (– 0.5) mm diam., rounded to flexuose, sessile on the thallus of the host. Disc flat or becoming somewhat convex in larger apothecia. Proper exciple concolorous with the disc, persistent, narrow, raised or level with the disc in older apothecia. Apothecial anatomy: Proper exciple opaque, appearing black even in thin sections, densely pigmented blue-green (Cinereorufa-green sensu Meyer & Printzen 2000) in the upper part, in the lower part beneath the hypothecium in mixture with a dark brown pigment, c. 20 – 45 (– 85) µm thick, composed of radiating, thick-walled hyphae with c. 2 µm wide lumina. Hymenium colourless or faintly blue-green, c. 50 – 75 µm tall. Epihymenium strongly blue-green (Cinereorufa-green), N + red, K−. Hypothecium colourless, without visible crystals in polarized light. Paraphyses simple or forked near the tips, septate and often slightly constricted at the septa, c. 1.5 µm in midhymenium, tips colourless, cylindrical to clavate, 1.5 – 2.5 µm wide. Asci of Lecanora - type, 8 - spored, clavate, 41 – 49 × 12 – 19 µm. Ascospores broadly ellipsoid to globose, (7.5 –) 8.66 ± 0.97 (– 11) × (5.5 –) 6.81 ± 0.71 (– 8.5) µm; l / b ratio (1 –) 1.28 ± 0.2 (– 1.67) (n = 57).	en	Svensson, Måns, Westberg, Martin (2021): A new lichenicolous species of Carbonea (Ascomycota, Lecanoraceae) from northern Sweden.

522A16765A091014FF50FF6BFD02FBDC.taxon	distribution	Distribution and habitat: — The species is so far known from two localities in northern Sweden. Its host Tephromela atra, however, is a common and widespread lichen on both calcareous and non-calcareous rocks. We searched for Carbonea tephromelae in 264 collections of T. atra sensu lato in herb. UPS, of which 183 were from Europe, 29 from North America, 22 from Oceania, 14 from Asia, 12 from South America and 4 from Africa, without finding any additional specimens. Most of the examined collections were from lowland localities, and it is possible that C. tephromelae is restricted to or at least more common in alpine to subalpine localities. Additional specimens examined: — SWEDEN.
