Underside white to cream to gray [or ochre in age], wrinkled (merulioid). Microscopic features: hyphae without clamps. A few hyphae with small incrustations. The underside may turn pinkish orange after storage in a herbarium (or at least under Dan's desk).
- Similar species
- The common Irpex lacteus has underside with jagged pores to flat teeth (microscope: encrusted cystidia). Plicatura nivea is a northern species on alder (Alnus).
- Ecology
- Saprobe on dead hardwoods, causing a white rot.

- April, July, October to early December for the known Chicago Region records. Elsewhere it is recorded throughout the year, though less in summer. Mostly winter and spring in the West.
