Abstract: The soil-inhabiting X. guepini was originally described from France in the early 19th century but has since been collected only infrequently. A collection of X. guepini in excellent condition was made, allowing us to study its sexual morph closely and to obtain cultures, from which we describe its Xylocladium-like asexual morph for the first time. Molecular phylogenetic analyses confirmed X. guepini belonging to Xylaria subg. Pseudoxylaria, within which it formed a subclade together with two other soil-inhabiting species, X. coprinicola and X. terricola.
Xylaria Hill ex Schrank is a widespread genus featuring a high species richness, shown to be paraphyletic by Hsieh et al. (2010). Many dubious or poorly known Xylaria taxa have been described (Ju, 2014), making the taxonomy of Xylaria often challenging. Xylaria subg. Pseudoxylaria (Boedijn) Dennis comprises ca. 40 species associated with termite nests or soil […]
