Hirose & K. Watanabe 2021	<div><p>Mariannaea imbricata D. Hirose &amp; K. Watanabe sp. nov. (Figure 3)</p> <p>MycoBank no.: 840111</p> <p>Description:</p> <p>Sexual morph not observed. Colony diam., 7 d, in mm (average): PDA: 5˚ C (2), 10˚ C (8), 15˚ C (11), 20˚ C (26), 25˚ C (31), 30˚ C (31), and 35˚ C (no growth); MEA: 25˚ C (34). Colonies on PDA at 25˚ C, matted felt at center, indistinctly zonate, with undulate margins, irregularly oriented and coarsely undulated, producing radially oriented fan-shaped structures from the center to margin, amber with white margin and reverse sienna with white margin. Colonies on MEA at 25 ° C, matted felt at center, indistinctly zonate, with undulate margins, irregularly oriented and coarsely undulate, producing radially oriented fan-shaped structures from center to margin, white with ochreous margin, and reverse umber with fulvous margin. On PDA: hyphae 1.4‒6.3 µm wide, hyaline, smooth, thin-walled, branched and septate. Conidiophores 167.7‒798.4 µm (mean 451.0 µm, n = 50) long, 3.7‒8.5 µm (mean 6.1 µm, n = 50) wide at the basal cell, generally macronematous, mononematous, erect, septate, smooth thin-walled, hyaline, bearing short branches with 1–2 whorls of 2–5 phialides, or phialides formed in verticils on long main stalk. Phialides 6.2‒16.9 × 1.2‒2.4 (mean 10.4 × 1.7 µm, L / W 6.2, n = 50), typically slender flask-shaped, hyaline and smooth-walled. Conidia 4.7‒10.9 × 1.8‒3.2 µm (mean 6.2 × 2.5 µm, L / W 2.5, n = 50), generally fusiform to ellipsoidal, hyaline, smooth and thin-walled, aseptate and produced in imbricate chains. Chlamydospores 7.2‒22.2 × 4.6‒12.3 µm (mean 10.8 × 6.2 µm, L / W 1.7, n = 50), intercalary or terminal, produced singly or in short chains, globose to sub-globose, hyaline and thick-walled.</p> <p>Etymology:</p> <p>The epithet “imbricata” refers to the irregularly oriented and coarsely undulate morphology from the center to margins of colonies grown on PDA and MEA.</p> <p>Type: Sugadaira, Nagano, Japan, 2008, isolated from the decayed needles of Pinus densiflora (Holotype, TNS-F- 91410, dried culture on PDA; ex-type culture, NBRC 33105).</p> <p>Notes:</p> <p>Mariannaea imbricata is morphologically similar to M. atlantica, M. fusiformis, M. punicea, and M. terricola, but can be distinguished from these congeners by its slender flask-shaped phialides with a smooth-walled texture. The colonies are characterized by an amber to white pigmentation on PDA and a central matted felt texture, and with the center to margins irregularly oriented and coarsely undulate on PDA and MEA. This species does not form reddish-purple colonies. Phylogenetic analysis based on ITS and TUB-2 sequences can also be used to distinguish these species.</p> </div>	http://treatment.plazi.org/id/6E00B52EFFA7214BFF53F886FACA6851	Public Domain	No known copyright restrictions apply.
