Observation 147623: Albatrellus ovinus (Fr.) Kotl. & Pouz.
When: 2013-10-04
No herbarium specimen

Notes: Arora, Mushrooms Demystified (2nd ed. 1986), at 558, says that A. ovinus is “widespread” and that A. avellanus is the “the purplish-capped form” form of A. ovinus.
Pacific Northwest Key Council, Annotated Key to Pacific Northwest Polypores (2007) fn 24 says:

Albatrellus ovinus (Sheep Polypore) and A. flettii (Flett’s Polypore) Although similar in habitat, size, and general appearance, A. ovinus has a white to ivory colored pileus, whereas A. flettii has a grayish blue pileus that fades (on exposure to sunlight?) leaving the pileus pinkish buff to pale orange-brown. … Two other species of Albatrellus have basidiocarps that resemble those of A. ovinus. Albatrellus avellaneus is initially white and develops obvious yellow tints, prefers the Pacific coast under hemlock and spruce, fruits in the late autumn and has basidiospores 5-5.6 × 3.6-4.2 μm, larger and not overlapping the basidiospore sizes in A. ovinus. Albatrellus subrubescens is like A. ovinus but has amyloid basidiospores.

The specimen in this observation was found in the Cascades rather than the Pacific coast.
Trudell & Ammirati, Mushrooms of the Pacific Northwest (2009), at 255, says “Albatrellus avellaneus is very similar to A. ovinus, which apparently does not occur in our region”. The photo of A. avellaneus shows a white mushroom.
