Spathulatum

Spathulatum is a genus of fungi in the family Cortinariaceae. It was circumscribed by mycologist E.J.H. Corner in 1950. The name is derived from the Latin word spathe, meaning a covering or leaflet, and the suffix -ulatum, which denotes a condition.

Spathulatum species are largely found in tropical and subtropical regions of the world. They are part of the larger group of ephemeral fungi that appear in specific habitats and under certain conditions. Members of this genus exhibit features that are characteristic of their genus, including cap shapes and gills that are gregarious or densely packed.

Some species of Spathulatum have been found associated with the mycorrhizal fungi ectomycorrhizal relationships in tropical forests. In particular, the genus includes species that can engage in symbiotic mycorrhizal relationships with certain tree species found in such ecosystems. However, the role of Spathulatum in these relationships is not well understood.

One of the most distinctive features of the genus Spathulatum is the structure of its gills. These gills are interwoven or crowded together, giving the cap a dense appearance. Spathulatum caps may have various colors and patterns, including green, yellow, or gray. Further research is necessary to determine the roles that these species play within their respective ecosystems and their relationships with surrounding organisms.

In addition to Spathulatum's interesting biological characteristics, variations in the species' modes of habitat and life cycles require further scientific study. These fungi, like those in the family Cortinariaceae, pose interesting research avenues regarding understanding the interactions between these microscopic organisms and the changing environments in which they find themselves.
