Truffle Genus: Setchelliogaster

Kingdom: Fungi Phylum: Basidiomycota Order: Agaricales Family: Bolbitiaceae |
Spore Characters
Setchelliogaster cannot be separated from Hymenogaster, Descomyces, or Descolea on the basis of spores alone. It differs from Thaxterogaster, which has a fibrous, often slimy cap, by having a layer of rounded cells on its cap. Whereas Thaxterogaster is closely related to Cortinarius, Setchelliogaster is closely akin to the mushroom genus Descolea as described by Bougher and Malajczuk and the truffle-like Descomyces. It differs from Descolea, which has a prominent stem and fully exposed gills, by having a much reduced stem and contorted gills or chambers mostly enclosed within a peridium. Hymenogaster and Descomyces have no stem and small chambers totally enclosed within a peridium.
