Subulicystidium longisporum

On decaying decorticated wood on the ground, both of conifers and broadleaved trees, with resupinate basidiomes, greyish-white, with a smooth, slightly farinaceous surface, very thin, closely adnate to the substrate, and with a diffuse growing margin.

Monomitic hyphal system, composed of hyaline hyphae, moderately thick-walled, 1.5 to 3 µm wide, richly branched, often with encrustations on their surface, septate and with clamp connections at the septa.

Cystidia subulate, thick-walled, encrusted on their surface, 40 to 70 µm long, 3.5 to 5 µm wide, with a hyaline, crystal-free, and thin-walled apex.

Basidia suburniform, with a slight constriction in the middle, 12 to 14 µm long, 4 to 6 µm wide, with basal clamps, 4-spored.

Spores cylindrical to slightly fusiform, smooth, hyaline, thin-walled, 13 to 17 µm long, 2 to 3 µm wide, with an indistinct apiculus at one end, and with two or more large oil droplets (guttules) inside.
