Pileus: 1.4-2.2 cm wide, white staining reddish brown, convex, granulose, margin appendiculate and incurved
Lamellae: white, free, close, irregularly lamellulate
Stipe: 3.5-4 cm tall, 3-4 mm wide, white near apex changing to light reddish brown toward base, granular, terete, equal, flexuous, hollow
Odor: insignificant
Taste: not sampled
Habit: scattered
Substrate: hardwood and conifer duff
Habitat: mixed conifer/hardwood forest dominated by Pseudotsuga menziesii and Acer macrophyllum
Elevation: 296 m
Found growing under a bramble of Rubus ursinus next to a dead standing lower trunk of a tree, presumably Umbellularia californica. There appeared to be lots of rotting wood in the duff.
Voucher Collection 10513dll was collected on November 11, 2021 in redwood branchlet humus at the edge of road in the McKay Tract Forest north of Redwood Fields in Cutten, Humboldt County, California. Macroscopic features of 10513 were described from the photos taken by Pamela Largent. The collection was dried by silica gel. An ITS sequence was obtained as well as similar ITS sequences were provided by Sharon Squazzo.
The microscopic features of 10513 are characterized by its consistent, heterodiametric, basidiospores with xavg = 9.1 × 6.1 μm, small basidia with granules that are broader in the middle than the apex, the abundant cylindrical, colorless, capitulate, cheilocystidia that are somewhat strangulated and without granules, and pileipellis that is composed of tightly entangled hyphae with an encrusted pigment that correlates with darkish dot on the pileus center macroscopically. Macroscopically 10513 has a campanulate to convex pileus that is tranlucent-striate to the pileus center and the stipe which is not silvery striate but does have faint striations at the stipe base. Because of these features I could not identify it in my 1994 book.
Tiny Galerina growing with mosses on decaying Hesperocyparis sargentii wood. Pileus distinctly pointy-umbonate, ochre-brown to tan, darkest at umbo, striate towards margin, with whitish scurfy ornamentation.
Growing on mixed conifer leaf litter in riparian forest. Pileus light tan, ornamented in cinamon-brown dusty looking scales, colored like a snickerdoodle; often dimpled in the center and irregularly wavy at margins in typical omphalinoid fashion. Gills wavy, some shallowly crossveined, deeply decurrent. Stipe whitish at apex, fading to pinkish brown at the base.
Voucher collection 10549 has been sequenced. The ITS sequence indicates it is a unique species in the group of species centered around Entoloma rhombisporum . It was collected by my granddaughter Elodie Anderson from the forest on my property in Eureka California. It was solitary in the humus near coast redwood sitka spruce. Photos of the microscopic features of this species exist and the description of these features has been completed.
