Austroboletus brunneisquamus (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.

A metagenomic view on fungal diversity in freshwater lakes

“…While there are some true aquatic Agaricales and Mortierellales (Frank et al 2010, Embree andIndoh 1967), this order typically comprises terrestrial fungi. Manymembers of Russulales, Cantharellales and Boletales are mycorrhizal fungi which depend on plant hosts to sustain growth (Halling 2001, Bonito et al 2013, Xu et al 2021, Floudas 2021. Most members of the Polyporales are wood composers (Money 2016), members of Mortierellales, Tremellales and Cantharellales are saprobes in soil, and members of Botryosphaeriales, Tremellales and Pucciniales are known as plant pathogens (Batista et al 2021, Helfer 2014, Gams et al 2004, van der Klei et al 2011.…”
