Foraminispora

Foraminispora Robledo, Costa-Rezende & Drechsler-Santos 2017, in Costa-Rezende et al., Persoonia-Molecular Phylogeny and Evolution of Fungi, 39(1), 254-269. (2017)

Etymology: Referring to the basidiospores with hollow endosporic projections which are continuous until the exospore wall. Foramen means hole, while spora means spore in Latin.

Diagnosis: Similar to Amauroderma, differing by the spores with endosporic ornamentation as hollow columns, which are continuous until the exospore wall. Basidiomata annual, stipe pleuropodal to pseudomesopodal, pileus circular to spathulate. Pilear surface glabrous, greyish brown to dark brown, concentrically zonate with thin blackish bands, radially rugose. Context white, homogenous, in section with a shiny black cuticle. Tubes slightly darker than context. Pore surface whitish to vivid orange. Pores regular, circular to angular. Dissepiments thick, entire. Stipe cylindrical, pale to dark brown, finely tomentose, solid to hollow, context homogeneous, whitish, in section with a shiny dark cuticle. Hyphal system dimitic, generative hyphae clamped, arboriform and skeleto-binding hyphae almost hyaline, dextrinoid. Cystidia and cystidioles absent. Basidia clavate, with four sterigmata. Basidiospores subglobose, hyaline to pale brown, double walled, with conspicuous ornamentation as endosporic projections column-like, some of them with a hole, that persists up to the exospore, IKI-.
