• Comments

  Pithya cupressina is a small, orange cup fungus found on decaying litter of cypress relatives and redwood. Unlike some cup fungi, it is seldom found in the open, but fruits in deep shade or on partially buried duff, a likely reason for why it is seldom collected. Pithya vulgaris is similar but larger. According to the literature it occurs on needles of Abies (fir), Picea (spruce), and Pinus (pine). Compare with Cheilymenia species which occur mostly on dung; Scutellinia species differ in having long, marginal hairs; Aleuria aurantia typically is larger, cupulate, and terrestrial; Caloscypha fulgens is also larger, cupulate and terrestrial, but in addition tends to discolor bluish with age and handling.
