When spotted in MA in 2009 they thought it was a hydnaceous fungus. However it lacked a pileus, and was resupinate. They determined through DNA that it was this species, a crust, “easy to identify … because of its long spines and large, pale luteous fruiting bodies.”

Here’s the macroscopic description from the article:

“Fruiting bodies resupinate for up to ~30 cm, with spines white to pale lutelous, densely crowded, 8 to 12 mm long, odor lacking. When dry density of the spines varies from adjacent spines touching to 2 mm between spines. Spines up to 10 mm long, slender, straight, round in cross section, gradually narrowing to a fine, acute tip, i.e., not pilose, penicillate or fimbriate. The space between spines snow white, smooth, glabrous. Small spines extend to within 0.5 mm of the margin. Margin white, appressed, dense, typically 0.5 mm wide but in areas up to 2 mm wide, the extreme edge finely fimbriate. Context white, < 1 mm thick, dense, fibrous to horny.”

Bill Neill wrote after seeng my pictures, “I think what you are considering a Hericium may be Radulomyces copelandii.” Garrett Taylor also suggested this. It matched the description in the article about Asian Beauty taking hold in Massachusetts. When I saw this one I recognized it.
