Boidinella globulispora

Boidinella globulispora (Boidin & Lanq.) Nakasone 2011, in Nakasone, Cryptogamie, Mycologie, 32, 191-197 (2011)

Basionym: Dendrothele globulispora Boidin & Lanq., in Boidin, Lanquetin & Duhem 1996

Diagnosis: Basidiomata resupinate, widely effuse, linear to orbicular colonies becoming confluent, up to 10 × 2 cm, thin, up to 350 μm thick, adnate, smooth, following contours of substrate, soft, thickly farinaceous to membranous, yellowish white (4A2), pale yellow (4A3), or greyish orange (5B3), bruising brownish orange (5B4) near margins; cracks none; margins adnate, abrupt and distinct or thinning out, pruinose to subfelty. Hyphal system monomitic with clamped generative hyphae. Subiculum a loose tissue of distinct, even hyphae and embedded cystidia; subicular hyphae 1.5-2.5 μm diam, clamped, moderately branched, walls hyaline, thin, smooth, cyanophilous. Hymenium composed of dendrohyphidia, cystidia, and basidia. Dendrohyphidia scattered, intricately and finely branched, 30-40 × 1.5-2 μm, clamped at base, walls hyaline, thin, smooth. Cystidia of three types: (a) scattered, obclavate, elongate, tapering gradually to an obtuse apex, (30-)70-90(-125) × 8-19 μm, clamped at base, protruding 50 μm or more, walls hyaline, thin, smooth, cyanophilous; (b) enclosed, scattered to abundant, obclavate to subfusiform, apex moniliform or bulbous, 30-60 × 6-10 μm, clamped at base, terminal or lateral, walls hyaline, thin, smooth, cyanophilous; (c) enclosed, clavate to obclavate with rounded or subacute apices, 25-60 × 9-11 μm, clamped at base, often empty, occasionally dark pink in phloxine, walls hyaline, thin, smooth, cyanophilous. Basidia collapsed soon after maturity, urniform to suburniform, 23-32 × 7-8 μm, clamped at base, often with oleaginous contents, walls hyaline, thin, smooth, cyanophilous, 4-sterigmate, sterigmata up to 8 × 1 μm. Basidiospores broadly ellipsoid with a small apiculus, (7-)8-9(-9.3) × (5.5-)6-6.5(-7.2) μm, average (n = 35) 8.2 ± 0.7 × 6.2 ± 0.4, Q = 1.3, walls hyaline, up to 0.7 μm thick, smooth, cyanophilous, not reacting with Melzers reagent.

Index Fungorum Number: IF561244
