Observation 76776: Lactarius crassus (Singer & A.H. Sm.) Pierotti

Found this on several occasions over August and September in various parts of this forest. Overall size varied from 4-7 cm across; the stipe was always quite short, 0.5-2 cm long. Pileus slightly centrally depressed in most specimens. Lamellae were considerably distorted, and covered when young by a very thin peridium, which disintegrated in age. The fruiting bodies were pinkish-buff overall when fresh, becoming more brownish in age and when dried. They exuded a scanty, thin, white, unchanging latex. Some specimens had a slightly fruity odor – Gayle Russell, another observer, described it as “like dried apricots.” The taste was always extremely acrid!

Growing most likely with Abies concolor, but Pinus lambertiana, Pinus ponderosa, Pinus jeffreyi, and in one case Abies magnifica, were present as well.

Species Lists


A fresh one, sliced open – latex is visible, though slight.
The underside of a dry one: the clump of dirt is at the base of the very short stipe.
This one was drying out when I found it. You can see the brownish flesh and surface, compared to the fresh one above.
