Crust Fungi

[ Basidiomycetes > . . . Various . . . ]

by Michael Kuo

I'm using the unscientific term "crust fungi" to refer to various wood-decomposing mushrooms that have a smooth to pimpled or wrinkled spore-bearing surface; they lack the pores that typify polypores, or the teeth that typify the toothed mushrooms. One good way to see the difference is to compare two classic and common wood rotters: the polypore Trametes versicolor and the crust fungus Stereum ostrea (sometimes called the "Turkey Tail" and the "False Turkey Tail," respectively). From above these mushrooms look very similar, but when turned over the polypore has very tiny pores, while the crust fungus has a smooth undersurface.

My treatment of crust fungi is unfortunately cursory (for the time being, at least), and centered around the larger, fruiting-body-developing species; there are multitudes of resupinate crusts that require painstaking microscopic analysis for accurate identification, and my interests tend to be more "mushroom" oriented. But I find the crusts interesting, and hope to give them, some day, the attention they deserve.
