Lachnellula calyciformis
Phytopath. Z. 53: 124. 1965.
Common Name: none
For description see Minter.
Gregarious on the bark of dead conifers (pine & fir); common, fruiting from spring through summer in the Sierra Nevada.
Unknown.
Lachnellula calyciformis can be distinguished by its tiny, shallowly cupulate fruitbodies with yellowish orange hymenium, an external surface covered with relatively long, white hairs, ellipsoid spores, and growth on the bark of dead fir branches. It is easily confused with Dasyscyphus bicolor, but the latter grows on hardwood sticks in riparian habitats and has longer fusoid spores. Pithya cupressina is about the same size and color, but the external surface is orange and lacks white hairs, the spores are globose, and it grows on the scale-like leaves of members of the cypress family.
