Xeromphalina setulipes

Xeromphalina setulipes is a species of fungus of the family Mycenaceae. It is known only from oak forests in Ciudad Real Province, Spain. Morphologically, the dark colour of the gills and stem, lack of a strong taste, and characters of the cystidia are the most distinguishing characteristics.

About Xeromphalina setulipes in brief

Summary Xeromphalina setulipesXeromphalina setulipes is a species of fungus of the family Mycenaceae. First collected in 2005, it was described and named in 2010 by Fernando Esteve-Raventós and Gabriel Moreno. It is known only from oak forests in Ciudad Real Province, Spain. Morphologically, the dark colour of the gills and stem, lack of a strong taste, and characters of the cystidia are the most distinguishing characteristics of X.  setulipes. The species produces mushrooms with dark reddish-brown caps up to 15 millimetres across, dark purplish- brown stems up to 45 millimetre in height and distinctive, arched, brown gills. It seems most closely related to X. fraxinophila, X.cornui, X  campanelloides and X. cauticinalis, but further analysis is required to accurately judge the relationships between the species.

Within the genus Xeromphalinas, it is classified in the section Mutabiles, along with several other species. Data from the large subunit of the nuclear ribosomal RNA gene suggests that the species is most closer to X campanelloide than X. setuliped. Further research, analysing the ITS or RPB2 loci, could serve to help clarify the precise relationships of species and positions of clades within the genus. The cap is dark brown, sometimes with reddish colouration, when turning tobacco-brown, when it dries; this change is more noticeable at the margin. The stem measures between 30 and 45mm in length, though it is thicker by 2mm in width, and instead of undulates it is undulates instead, instead of being undulates.
