vibrissa

Type species:

Nia vibrissa R.T. Moore & Meyers, 1959. Mycol., 51: 874.

Basidiomes: 1-3 mm in diam., solitary or gregarious, subglobose, superficial, anchored in the substrate with an inconspicuous, cylindrical pedicel up to 80 µm in diam., whitish, yellowish, pinkish, and finally orange-coloured, soft, thin-walled, villose or smooth, containing homogenous gleba, opening by irregular rupture of the peridium. Hyphae: 2-3 µm in diam., septate, ramose, with clamp connections, hyaline. Peridium: 10-15 µm, bearing on the outside long hairs up to 275 µm long, 4-7 µm in diam., thick-walled, straight or curved, sometimes slightly curled apically and incinate. Gleba: at first composed of hyphae with inflated tips of 15-25 µm in diam. (protocyst), later replaced by basidia developing at random throughout the venter. Basidia: 35-50 x 2 µm, with an apical subglobose inflation, 10-12 µm in diam., bearing at the round apex four- to eight basidiospores; hyaline without sterigmata. Basidiospores: 9-15 x 6-11 µm, ovoid or ellipsoidal, one-celled, hyaline, with several slender appendages. Appendages: at the apex provided with a single, slender, flexible, attenuate, hyaline appendage, 20-47 x 1 µm, terminally slightly inflated; four (rarely 3 or 5) similar, sub-terminal, radiating appendages around the base, 20-32 µm long; at the point of attachment to the basidium with a short cylindrical projection. Asexual morph: Undetermined (Description based on Moore & Meyers (1959); Ginns & Malloch, (1977)).
