Description
The Trembling Crust (Merulius tremellosus) is a decomposer of wood and is usually found growing on the side of large fallen tree trunks. It fruits in the late spring through fall and overwinters as a dried up version of its former self.
The hymenophore features an array of patterns appearing wrinkled, pocketed, or angularly poriod with colors of red, pink, or purple. The spore print is white.
It can sometimes form a cap when angled appropriately alongside the tree, appearing as both a shelf and a crust (a form called effused-reflexed).
