Stipe: 0.5 mm tall, 0.2 mm wide, white, hairy
Odor: insignificant
Taste: not sampled
Habit: gregarious
Substrate: old Rubus armeniacus cane
Habitat: urban park forest with Populus trichocarpa, Pseudotsuga menziesii, & Arbutus menziesii
Elevation: 13 m
Hairs: clavate to subclavate, mostly 60-70 µm x 3-4 µm
Paraphyses: lanceolate, longer than asci, avg 60 µm x 5 µm
Asci: cylindric, avg 45 µm x 4 µm

Growing on burnt wood in chaparral. Ochre, hydnoid-resupinate fungus with a wrinkled edge.
The velar remnants and stipe texture remind me of a Pholiotina.
Spores 8.5-9.5 microns (some smaller, some up to 11 microns long).
Ochre brown in KOH. Germ pore present.
Cheilocystidia sinuous-cylindrical, some distinctly lageniform. 40 microns long.
Caulocystidia scarce, cylindrical, in clumps, arising from center of hypha or subterminal on swollen hyphae.
Clamps present fairly easy to find.
Pileipellius a hymeniform layer of round cells, scattered pileocystidia cylindrical, some clamped and septate.
Substrate: old Populus trichocarpa log.

Alder. Kept hair ice stick moist in boot room. Thin skin of Exidiopsis showed up 3 weeks later.

2020-05-26_MLB01, collected near spruce, birch, stunted cottonwoods, and grasses.
Specimen collected.
Update: Fruiting from a decaying coniferous log in a moist micro-climate of a steep, dry, seasonal streambed in mixed Pinus, Pseudostuga, and Abies forest.
8-spored ascii. Spores ellipsoid, smooth, hyline, eguttulate, and averaged 17.4 x 10.8 microns. All macro and micro features are a good match for C. vernalis

In a small stream, growing on saturated wood a few inches above water, around 1800ft elevation. Spores smooth, 20.1-21.3 x 9.2-10.3.
The largest apothecium is 15mm.
Ascospores measure in H2O
(17.1) 17.3 - 18.5 (18.8) × (11) 11.4 - 11.8 (12.4) µm
Q = (1.4) 1.5 - 1.6 ; N = 17
Me = 17.9 × 11.6 µm ; Qe = 1.5
Found under Corylus on twig of the same. Not many spores present, but averaged 13x7.5 microns.
Found by @leah_mycelia on still attached Pseudostuga twig (!!)
Found these lively, tiny mushrooms on the bark, in the moss and lichen of our magnolia. They are 1/8th of an inch at best and most are far smaller.
