High elevation chaparral and mixed forest, Pseudotsuga macrocarpa, Pinus ponderosa, Quercus chrysolepis, Hesperoyucca whipplei.
Growing on leaves and twigs submerged underwater ~4 in deep in mildly turbulent stream from snowmelt runoff. Area had been covered in snow two weeks previously, but it was absent at the time of the observation, with last traces visible in between peaks at the highest elevation.

Most caps clearly developing and expanding underwater; others starting above water out of saturated margins of the stream. “Aquatic” caps bursting through layer of algae on surface of the water, but no algae on the underwater substrate.
Underwater caps alabaster at button stages, expanding to brown with white cracked pattern. Above-water caps more dome-shaped, velvety, zonate. Both hygrophanous. Gill margins white; consistent feature.
Stipe lacking annulus, extraordinary flexible for Psathyrella. Rigid inner layer (revealed by microscopy to be a dark conglutination) and a squishy, plastic-bag-like outer layer (consisting of lighter hyphae in pyramidal ridges).

Spores deposit purple black. Spores cigar brown. KOH+ fuscous. With apical pores. [11.8] 12.25-13.18 [13.9] x [6.2] 6.62-7.2 7[7.8] μm
Q [1.71] 1.74-1.89[2]

Spores measured from spore print deposited from mushroom cap that developed underwater; evidence for this is the presence of diatoms in the cross section of this mushroom.

On this same cross section are spores that appear to have germinated on the gills.

From microscopy, compared to P. aquatica the basidia of this specimen are more obtuse and pleurocystidia more elongate. The spores and cheilocystidia are similar.

Dog-found in the Holiday Farm Fire burn area (burned in Sept 2020). Douglas fir forest with a few incense-cedars. Burn low to moderate severity. Spores larger than an Oregon black truffle's spores and refuse to squash free from the flesh. White latex when cut. Fruit body was very firm/dense.

~1 mm growths attached to dangling dead portions of a Salmonberry stem. I checked back on these a few weeks later and they remained unchanged in appearance. Currently stumped as to where to even start in narrowing down the ID -- any and all ideas would be awesome!

Grows loosely attached to bark on living Quercus garryana. Hymenium lacks pores but looks finely granular probably due to very large basidia (up to 50 microns beyond rest of hymenium and long sterigmata (10-20 microns long. Spores are amyloid, roughened, thick-walled with refractive content, average 15.9 x13.8 microns. They have a small pip. Another possibility is Aleurocystidiellum. No good species match.

Growing out of mango wood chips, gregarious,

Gills: free crowded, butter colored. Lamellulea: 3 series
Stipe: hollow, tapering upward from sub-bulbous squamulous base, stipe staining readily reddish orange and fading to grey brown.

Annulus present.

Cap: 15-70mm convex to pano convex, white with brown/Black concentric scales/dots radiating from central broadly mammillate apex. Margin crenulate/wavy and semi striate.

Odor: fungal with light smell of anise
Taste: mild/none

This observation is for the fungi.

Western Thatching Ant (Formica obscuripes) clinging to grass stem, with unknown entomopathogenic fungi. The two springtails are Entomobrya triangularis and appeared to be eating either the ant, the fungi, or both. Photos of the same ant one day earlier (with abdomen still intact) are here:

Only found near redwoods in burned patches. Thousands of them. Stringy stipe, non-attached gills, have a "root" like redwood rooters, Dirty & dark brown/blackish caps. Pure white stipe. Minimal bruising, but develops into a dirty white/brown colored stipe in age.

Found in wet mossy ground under Thuja plicata and Pseudotsuga menziesii in a steep creek draw. Compare to: https://www.inaturalist.org/observations/43028599 and https://www.inaturalist.org/observations/52510244.

The beautiful white fungal filaments sprouted from an oak branch covered with a corticioid fungus. The branch/stick was left in a humid box mixed with six other pieces of wood covered with different corticioid fungi species. Only the oak branch with the orange corticioid fungus sprouted the white filaments. None of the others sprouted any white filaments. Interesting. Were the white filaments growing ON the corticioid fungus and were not part of it?
