Agaricomycetes, Subclass Agaricomycetidae






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)).

Pertinent Literature:
NOTES: Nia vibrissa was initially regarded as an asexual fungus, but later basidia and basidiospores, clamp connections were found (Doguet 1967 1968) and variously assigned to the Melanogastrales (Dring 1973), Nidulariaceae (Rossello et al. 1993) Niaceae (Jülich 1981). Molecular data placed it in the eugarics clade, forming a sister clade to Henningsomyces candidus (Binder et al. 2001, Hibbett & Binder 2001). A well-researched species at the physiological, ultrastructural and molecular level and ecologically occurring worldwide from temperate to tropical locations. Currently three species are accepted: N. globospora, N. vibrissa and N. epidermoidea (Jones et al. 2015). Further collections are required as only N. vibrissa has been sequenced. Nia vibrissa may be a species complex and wider taxon sampling is required (Jones & Jones 1993, Binder & Hibbett 2001).
