Coltricia perennis (L.) Murrill - Tiger's Eye

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Polyporales

Although most polypores grow as either crusts or brackets, there are a few that form cup-like fruitbodies. One of these is Tiger’s Eye, a very attractive cup-and-stem fungus that grows in humus-rich sandy soil on woodland edges and on acidic heathland.

Young specimens have downy infertile (upper) cap surfaces but the down is only transient; older caps usually have radial furrows and irregular, wrinkled margins.
