<i>Austroboletus brunneisquamus</i> (Boletaceae, Boletales), a New Ectomycorrhizal Fungus from a Tropical Rainforest, China

Abstract

Austroboletusbrunneisquamus (Boletaceae/Boletales), an ectomycorrhizal fungus, is described as a new species from a tropical rainforest in China based on morphological and molecular evidence. It is morphologically characterized by a subtomentose pileal surface when young, which cracks into areolae, having large, pale brown and brown to dark brown scales, a stipe with yellowish brown reticulation, basidiospores measuring (11–)12–14.5(–15) × 6–8(–8.5) μm, with fine cristate to subreticulate ornamentation, and a pileipellis in the form of a cutis. A detailed description, color photographs of fresh basidiomata, and line drawings of microscopic features of the new species are presented.
