Etymology. Multiforus (Lat., adj.)—perforated.

Diagnosis: Basidiocarps effused, smooth, reticulate, semitranslucent, bluish-greyish in fresh condition, greyish-brownish when old or dry, gelatinized, up to 1 cm in widest dimension, 0.030.05 mm thick, margin concolorous with hymenium, gradually thinning-out. Hyphal structure monomitic; hyphae clamped, thin-walled, 11.5 μm in diam., densely arranged. Cystidia abundant, clavate to skittle-like, thin-walled, 3248 × 4.57.5 μm, solitary or in groups of 25. Hyphidia present, normally associated with cystidia, 0.50.8 μm in diam. at the apex, thin-walled. Crystals absent. Basidia 4-celled, globose, 78 μm in diam., sessile or with a strongly reduced stipe up to 1 × 1 μm, sterigmata up to 3.5 × 1.5 μm. Basidiospores broadly cylindrical to narrowly ellipsoid, (4.8–) 5.16.2 × (2.9–) 3.03.8 (–3.9) μm  (n = 30/1), L = 5.62, W= 3.36, Q’ = (1.4–) 1.51.9 (–2.0), Q =1.68.
