Phlebia radiata is an orange to pink crust fungus that spreads itself across the dead wood of hardwoods and conifers across North America. It has a wrinkled surface in which the wrinkles radiate outward, more or less, from a central location. It does not develop pores, and it does not develop a cap structure or even, usually, a folded-over edge.


Ecology: Saprobic; spreading across logs and stumps of hardwoods or conifers; annual; causing a white rot; spring, summer, fall, and winter; widely distributed in North America.

Fruiting Body: 1-10 cm or more across; irregular in outline; up to about 3 mm thick; surface wrinkled, with the wrinkles and folds radiating from a more or less central point; orange to pink (more rarely tan with orangish edges, or purplish); occasionally developing a slightly folded-over, hairy edge.

Spore Print: White.

Microscopic Features: Spores 4-5.5 x 1.5-2 µ; smooth; sausage-shaped; inamyloid. Cystidia cylindric to clavate; up to about 100 x 10 µ. Clamp connections present.
