Neohygrophorus is a genus of fungus placed in the family Tricholomataceae for convenience. The type species is a typical gilled snowbank mushroom found at higher elevations in the western mountains in North America. The two other known species are found in mountainous areas in eastern North America in the Appalachian Mountains and in the Atlas Mountains in northern Africa during periods of cold weather.[2][3][4][5][6] In earlier classifications based on anatomy prior to DNA sequence-based classifications, the unusual combination of features led taxonomists to independently create two subgenera in two genera: Hygrophorus subg. Pseudohygrophorus[3][4] and Clitocybe subg. Mutabiles;[5][6] the latter based on Neohygrophorus angelesianus but described under a new species name which is now placed in synonymy, Clitocybe mutabilis. The genus continues to be anomalous. Phylogenetically, Neohygrophorus is in a tricholomatoid clade but not in the Tricholomataceae.[7][8] The closest genus is believed to be Pseudoomphalina.[7] Both genera have amyloid basidiospores and occupy an isolated position as shown in the phylogram for the Agaricales on Wikipedia.

Etymology

The name Neohygrophorus means new (neo-) Hygrophorus and was coined when the type was classified in the Hygrophoraceae within which it was differentiated by its amyloid basidiospores.
