Clustered Domecap

Lyophyllum decastes, the clustered domecap or fried chicken mushroom, is a robust saprotrophic or possibly mycorrhizal basidiomycete in the family Lyophyllaceae that produces large, densely clustered fruiting bodies at the base of dead hardwoods, stumps, or from buried wood and woody debris. The caps are grey-brown to tan, broadly convex to domed, often with wavy margins in crowded clusters. Gills are white to pallid, crowded, and sinuate. It is distributed across the northern hemisphere in broadleaf and mixed forests. L. decastes is edible and considered a choice food mushroom in parts of Europe and Japan, where its firm texture and mild flavor have earned it the English nickname 'fried chicken mushroom.' However, definitive identification requires care, as it can be confused with toxic lookalikes. Molecular studies have revealed that the concept of L. decastes may encompass multiple species or a species complex. The species is classified as Least Concern by the IUCN and is commonly encountered in autumn in temperate woodlands, parks, and roadsides across its wide range.
