Australovuilleminia
Australovuilleminia Ghob.-Nejh. & Hallenb. 2010, in Gorjón, Studies in Fungi 5(1), 168 (2020).
Diagnosis: Basidiome resupinate, decorticant, erumpent, closely adnate, reddish orange to coccine red, subgelatinous, margin indistinct. Hyphal system monomitic, hyphae with clamps, encrusted with reddish-orange matter, thin to thick-walled. Subiculum thin, composed of highly branched, irregularly arranged hyphae. Cystidia cylindrical, considerably thick-walled excepting in the apical part, contents homogeneous, yellowish to orange brown, not reacting in sulphovainilline neither in Melzer's reagent, slightly or conspicuously projecting above the basidial layer. Dendrohyphidia and hyphidia abundant. Basidia first tubular, becoming elongate, long clavate, flexuous, with 4-sterigmata, densely arranged in the hymenium and intermixed with numerous hyphidia and dendrohyphidia, with a basal clamp. Basidiospores allantoid, thin-walled, smooth, IKI–, cyanophilous.

Type Species: Australovuilleminia coccinea Ghob.-Nejh. & Hallenb. 2010
Notes: Australovuilleminia resembles Vuilleminia in its decorticating habit, presence of dendrohyphidia, large basidia and large basidiospores but differing in the well-developed basidial layer in a true hymenium and a distinguishable subiculum. Also, the striking red colour of the basidiome is diagnostic (Ghobad-Nejhad et al. 2010). Australovuilleminia is the austral counterpart of Vuilleminia and both genera are also phylogenetically closely related.
