Dacryobolus angiospermarum (Polyporales, Basidiomycota), a new brown-rot corticioid species from southern China

Abstract

A new corticioid species, Dacryobolus angiospermarum, is described and illustrated from southern China based on morphological and molecular evidence. The new species is similar to D. karstenii but differs in growing on angiosperm wood, having wider skeletal hyphae, and lacking hymenial cystidia. In the phylogenetic tree inferred from ITS and nrLSU sequence of Dacryobolaceae, D. angiospermarum formed a distinct lineage sister to the D. karstenii group. Samples of D. karstenii from southern China, north Europe and northwestern United States formed different lineages. However, no morphological characters can be used to distinguish them at present.
