Every Fingerprint tells a Story:

NCBI blast of ITS yields interesting ecological implications for this diminutive gray Trich -- appearing to be the/a fungal link between the mycoheterotrophic Hypopitys monotropa and the magnanimous Pinus ponderosa:

This Trich occurs in the southwest where it associates with Ponderosa Pine "ectomycorrhizal colonized root": https://www.ncbi.nlm.nih.gov/nuccore/MZ017995

also appears to associate with "Hypopitys monotropa root tip":

https://www.ncbi.nlm.nih.gov/nuccore/OQ832132

The only geographic data for the Hypopitys is "USA" -- GenBank submissions should have geographic location (at least to county and state)

Monotropa hypopitys is a mycoheterotrophic plant native to temperate regions of the Northern Hemisphere. Apparently recent genetic evidence strongly suggests that Monotropa hypopitys should be placed in its own genus, Hypopitys,

from Latinized Greek hypo-, "under", and pitys, "pine"

Fruiting beneath Douglas fir and vine maple.
Harvested two specimens.
Removed portion of cap and removed single gill with straight razors.
Mounted gill in 3% KOH.
Spores: elliptical to ovoid, large, roughened/verrucose, thick walled.
Basidia: both 2 and 4 sterigmate. Abundant on gill edge. Most 4 sterigmate.
No cystidia visible that I could find.
Dehydrated both specimens thoroughly and bagged for herbarium collection/genetic record.

Spore deposit cinnamon-brown. No distinct odor. Cap 2.5 - 6.5 cm across, hygrophanous. Stipe up to 17 cm long x 2 - 5 mm wide, hollow. Cheilocystidia and pleurocystidia lecythiform or tibiiform. Spores with germ pore, (7.8) 8 - 9.1 (9.3) x (5.6) 5.8 - 6.3 (6.4) µm, Q = (1.2) 1.3 - 1.5 (1.6), N = 25, Me = 8.6 x 6 µm, Qe = 1.4. Growing in duff under Picea sitchensis.

Pisgah unburned control. This site has evidence of a fire >>50 years ago as the oaks are resprouts, but they are large. Unburned only with respect to known historical fires.

Hanging down from the underside of an oak log (yes with Mollisia). Often in insect holes.

Quercus agrifolia, Arbutus menziesii, Arctostaphylos. Velvety cap. Broadly attached gills. BRIGHT yellow UVF on gills and stipe. Brown KOH reaction on cap. Odor reminiscent of a plant that I seem to recognize as toxic but can't remember the plant from just the odor

Odor not distinct. Cap 4 cm across. Stipe 7.5 cm long x 5 - 6 mm thick. KOH dark red on cap and stipe. UV365 negative on all surfaces. Growing in needle duff in a forest with Western Hemlock, Douglas-fir and Sitka Spruce. Spores rough, average size 8 x 4.5 µm.
