Isotropta

Isotropta is a genus of fungi in the family Tricholomataceae. The genus was described in 1982 by mycologist Rolf Singer. Species within Isotropta are generally characterized by their small to medium-sized fruiting bodies, often with a convex to flattened cap and a stem that is relatively slender. The gills are typically adnate to decurrent. Microscopically, Isotropta species exhibit smooth, amyloid spores. The taxonomic placement of Isotropta has been subject to revision, with molecular phylogenetic studies influencing its classification.

The ecological role of Isotropta species is primarily saprotrophic, meaning they obtain nutrients by decomposing organic matter, often found in woodland environments. The specific substrates they colonize can vary, but they are commonly associated with decaying wood or leaf litter. Distribution of Isotropta species is generally widespread in temperate regions. Identification of Isotropta can be challenging, often requiring careful examination of morphological features and microscopic characteristics. The genus is not widely known for culinary or medicinal uses, and information regarding potential toxicity is limited for most species. Further research is ongoing to clarify the phylogenetic relationships and ecological significance of this fungal genus.
