What is "leratiomyces"

Leratiomyces is a genus of mushroom-forming basidiomycetes first proposed three times under invalid names, and finally validated in 2008. It includes several formerly described, variously, from the genera Stropharia, Hypholoma, and Weraroa. It was formerly classified as Stropharia section Stropholoma, though some authorities placed this section in the genus Hypholoma, as these species often have features that are intermediate between the two genera.

This group includes a number of mushrooms found commonly in woodchip beds and dry grasslands or sandy soils, such as Leratiomyces ceres and L. percevalii. It also includes a number of secotioid species, including the type species, L. similis, as well as L. cucullatus, L. erythrocephalus and L. laetissimus.
