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.
