UV lighter irl. Under Salix in deep duff. Abco nearby. Fetid sweat smell
These 3 fruitings were quite far apart and on different ridges which is why I felt they warranted separate observations.
Emerging from crack in large log of fallen conifer, possibly Jeffrey pine. Log is charred farther down, but not in the immediate area where the mushroom is growing.
Cap dry, reddish honey-brown with white patches. Persistent white cortina. Young gills tan. Stipe yellowish bone color. Caespitose.
KOH red
FDS-CA-00741
In Pinus radiata and Quercus agrifolia dominated coastal mixed hardwood/conifer forest
Growing on edge of Pinus radiata wood chip pile
Pileus flat to depressed, velutinous, brown with faint concentric rings. Lamellae bright orange, crowded and ruffled in come specimens. Flesh very soft and delicate
Smell slightly funky, off-putting, like sewage
Taste indistinct
Bleaching KOH on cap
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.
