Description:Hyphoderma puberum (Fries) Wallroth, Fl. Crypt. Germanu 2: 576, 1833. (Fig. 42)

Basidiomata resupinate, adnate, at first orbicular and then becoming confluent, subceraceous, 60-300 µm thick; hymenial surface white, "Smoke Grey", "Buff" to "Honey", smooth, velutinous under the lens (x 20); margin concolorous with the hymenial surface, thinning out, indeterminate, sometimes fibrillose under the lens (x 20). In vertical section, subhyaline, membranous. Hyphal system monomitic; hyphae 2.5-5.5 µm in diam, smooth, thin- to slightly thick-walled (up to 1.5 µm), nodose-septate; lamprocystidia numerous, conical to fusiform, 60-140x 9-20 µm, with a basal clamp, at first thin-walled and naked, and then becoming thick-walled (up to 4 µm) and heavily encrusted, projecting up to 80 µm beyond the hymenial surface; basidia narrowly clavate, 20-45 x 6.5-8µmµm, with a basal clamp, producing 4 sterigmata; basidiospores narrowly ellipsoid to subcylin­drical, 9-12x 4-5 µm, smooth, thin-walled, non-amyloid.
