Summary: Lentinus strigosus is characterized by 1) a hairy, reddish brown or pinkish brown cap that is often violet when fresh and wet, 2) tough texture, 3) a short stem that is lateral to off-center or sometimes central, 4) growth in groups on rotting hardwood, and 5) a white to yellowish spore deposit. The online Species Fungorum, accessed on April 3, 2016 and July 16, 2019, gave the current name as Panus neostrigosus, but MycoBank, accessed on the same dates, maintained the current name as Lentinus strigosus. The description is derived from Arora(1) except where noted.
Cap: 2.5-10cm, "fan-shaped or wedge-shaped to somewhat irregular in outline", convex becoming flat or depressed, "margin incurved, often lobed"; reddish brown to tan, but often violet when fresh and wet; "dry, covered with dense, coarse, stiff, velvety hairs", (Arora), pinkish tan to reddish brown, or with violet tinge, tan when old, (Lincoff), "often purple at first, but soon fades to reddish brown, pinkish brown, orangish brown, or tan", (Trudell)
Flesh: tough, thin; white
Gills: "decurrent, close, narrow"; white, creamy or cap-colored; edges entire

Veil: partial veil absent (Miller)
Odor: none (Miller)
Taste: slightly bitter
Microscopic spores: spores 5-7 x 2-3 microns, elliptic, smooth, inamyloid, (Arora), spores 4.5-7.0 x 2.5-3.0 microns, short-elliptic, smooth, inamyloid, thin-walled; pleurocystidia and cheilocystidia clavate, thick-walled, (Miller)
Spore deposit: white or yellowish
Notes: It is widely distributed in North America (Lincoff). There are collections from BC, AB, and SK at the University of British Columbia. There are collections from WA, ID, IL, LA, MI, and MT at the University of Washington. There are collections from ON, IN, OH, and MO at Oregon State University. It has been reported from CA (Arora(1)).
