Coltriciella

Coltriciella Murrill 1904, in Dai, Y.C., Fungal diversity, 45, 131-343 (2010)

Diagnosis: Basidiocarps annual, stipitate, corky or brittle and light-weight when dry. Pilei rust-brown, velutinate, concentrically zonate or azonate, usually small, cap not exceeding 2 cm in diam. Pore surface brown; pores angular, 1–4 per mm. Context brown, coriaceous. Hyphal system monomitic; generative hyphae simple septate; tissue darkening in KOH. Basidiospores ellipsoid, subglobose or naviculate, mostly pale yellow to golden yellow or brown, rarely hyaline, fairly thick- to distinctly thick-walled, finely verrucose, mostly IKI–, rarely dextrinoid, mostly CB–, some CB (+). On ground or on decayed wood.

Externally the species of Coltriciella resemble those of Coltricia: they share brownish and stipitate basidiocarps, grow on the ground, and have a monomitic hyphal system. However, basidiospores of the Coltriciella are finely verrucose, while they are smooth in Coltricia. Phylogenetically these two genera make a strongly supported clade (Wagner & Fischer 2002; Larsson et al. 2006). Tedersoo et al. (2007) demonstrated that Coltriciella was placed in a monophyletic clade within Coltricia, and they confirmed four species of Coltricia and Coltriciella form ectomycorrhiza with the native trees in Seychelles. Their study provides further evidence that fruiting habit on dead wood does not indicate saprotrophic lifestyle.
