Phylogeny
The placement of Arachnomyces has changed multiple times due to its morphological similarities to members of different families. When first described in 1902, it was included in the old family Perisporiaceae. Later it was considered as part of Onygenaceae, then it was placed within the Gymnoascaceae in 1996. Thanks to phylogenetic analyses Arachnomyces is currently recognized as a distinct monophyletic lineage, composing its own family Arachnomycetaceae and order Arachnomycetales within the class Eurotiomycetes.
