 Scientific Name: Hyphodontia pilaecystidiata

Odontia pilaecystidiata S. Lund., Fungi Exsiccati Suecici 43–44: 24. 1953.

Hyphodontia pilaecystidiata (S. Lund.) J. Erikss., Symb. bot. Ups. 16: 104. 1958.

 Description: Macroscopic characters: Basidiocarps resupinate, widely effused, 1–1.5 × 18 cm, 400 μm thick, thin, soft, ceraceous or subceraceous, not cracked, white to light buff, not changing color in 5% KOH; margins thining out, floccose, concolorous; spines variable in shapes, mostly conical or aggregated in groups, 10–11 per cm, about 0.1 mm high or more. Microscopic characters: Basal layer of context almost absent; intermediate layer of context 75–200 μm thick, with longitudinally loosely interwoven hyphae arising laterally from the basal parallel hyphae at right angle; upper half of context including hymenial layer conglu-tinate in dark color, seemingly provided with crystals embedded among the agglutinized hyphae, about 125–200 μm thick; hyphae thin-walled, with clamp connections, smooth, 3–4.5 μm wide, distinctive at the basal part of context; cystidia only present in the hymenial layer and the region of spine, not immersed, having two types; the one capitate, with contents easily turning red coror in phloxine, thin-walled, smooth, 10 μm in diam., 5 μm wide at the base, scattered in the hymenial layer; the other restricted on spines, roughly encrusted at the upper part, 8.7–10 μm wide including crystals, 6 μm wide if not including crystals, protruding 12.5 μm high, 3.7 μm wide, flexuous, sometimes septate, with the crystals dissolved in 5% KOH; hymenial layer conglutinate; basidia not seen; basidiospores ellipsoid, 3–4 × 4–6.5 μm , smooth, with one distinct guttula, apiculate, non-amyloid.

 Note: This species is closely related to Hyphodontia breviseta (P. Karst.) J. Erikss., but can be distinguished from the latter by lacking moniliform cystidia and having larger basidiospores.
