Tomentella furcata, a new species from Benin (West Africa) with basidia forming internal hyphae

Original Article

Abstract

In this study, a new tropical African resupinate thelephoroid species, namely Tomentella furcata, is described. Microscopically, it is characterised by mostly simple septate and thick-walled (1–2 μm) subicular and subhymenial hyphae, suburniform basidia with transverse septa and/or infrequently with an internal hypha, large sterigmata of 2–4 μm at base, and distinctly yellow, subglobose to globose basidiospores (both in frontal and lateral view) with long (1–2 μm) and dense, simple or forked spines. Phylogenetically, T. furcata falls within terminal clades of investigated Tomentella species. We discuss ornamentation types of basidiospores for discrimination of resupinate thelepohoroid genera and confirm the limitation of ornament bifurcation as a diagnostic feature of Pseudotomentella. Anatomical dissimilarities between T. furcata and close species are given.
