A new species of Hymenochaetaceae, Fuscoporia ambigua sp. nov., is described based on specimens from the USA and China. The phylogeny, based on the ITS+nLSU+RPB2+TEF1 dataset, revealed that it nested within the Fuscoporia clade, and all the American and Chinese specimens of the new species clustered in a lineage with good support. The new species is characterized by its annual, resupinate basidiocarps with pores measuring 5–6 per mm, aseptate skeletal hyphae, presence of mycelial setae and cystidioles, long hymenial setae (45–75 μm) which are occasionally septate, presence of cystidioles, and ellipsoid basidiospores measuring 4.2–5.2 × 2.8–3.3 μm. Fuscoporia ambigua is very similar and closely related to F. ferruginosa, but the latter species has a perennial growth habit, and short and aseptate hymenial setae (30–44 μm).
A new polypore species, Fuscoporia subferrea, is described from southern China based on morphological characters and phylogenetic analysis. The new species is characterized by annual, resupinate basidiocarp, hyaline, thin-walled, smooth, cylindrical basidiospores measured as 4.2-5.8 × 2.2-2.6 µm. It resembles F. ferrea, but differs by smaller pores (7-10/mm vs. 5-7/mm) and narrower basidiospores (4.2-6.2 × 2.0-2.6 µm vs. 4.2-5.2 × 2.8-3.5 μm). Phylogenetic analyses inferred from the ITS and nLSU sequences indicate that the new species forms a distinct lineage with strong support and is closely related to F. ferrea.
A new species, Fuscoporia hainanensis sp. nov. (Hymenochaetaceae, Basidiomycota), is decribed based on specimens from China. Phylogenetic analyses on the nLSU and ITS+nLSU+TEF1 datasets revealed that the new species was nested within the F. contigua group and formed a strongly supported lineage distinct from other species. The new species is characterized by annual, resupinate basidiocarps with medium pores (4–6 per mm), aseptate skeletal hyphae, presence of mycelial setae, hymenial setae and cystidioles, and cylindric basidiospores (5.0–6.2 × 2.3–3.0 μm). A key to the accepted period species of resupinate and mycelial setae present species of Fuscoporia is provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
