Parasite fungus on Aleurodiscus grantii noticed on iNaturalist observation by Connor.
Harte was able to pull out sequences from the parasite from the nanopore data.

https://www.inaturalist.org/observations/165851683

Hygrocybe fenestrata - the skinny yellow kind. Seen this type on Hygrocybe hill but different from the one at squaxin and on Maury island

Fruiting from dirt bank near a cedar and a patch of H. flavescens.

caps slimy/viscid but not as much as the more red-orange H. fenestrata, which feels like a Gliophorus or H. flavescens. caps yellow-light yellow.. translucent-striate. whit on cap margin. 1.6-2.7cm diameter

yellow-white gills medium spaced, broadly attached to notched,

stipes sort of viscid, but more on the moist side. the largest fruit had a nearly dry stipe. pure white with the subtlest of yellow blush.

0.2-0.4cm thick
4.3-9.2cm long

On interior surface of bark from well-decayed alder log under unidentifiable rotting agaric, maybe a Clitocybe? Long fibers along the entire length of stipe, shorter fibers on cap appearing powdery silver, easily brushed away revealing smooth dark cap. Gills with blue UV fluorescence

Yellow/orange brainy resupinate fungus

Growing from a sodden, dead log overhanging Near East Fork Barton Creek, San Bernardino NF
Irregular, brain-like growth patters, almost looks like bacteria on a petri plate. White mycelial filament extending from the growing edge
Smell indistinct
Slightly allowing KOH

On grass trailside in damp, very protected north facing slope, abundant. Excipulum hygrophanous, fading to white. Fruitbodies concave to flat when young, pink-red, becoming pulvinate and nearly scarlet color in age

sometimes growing in large numbers, densely and gregariously, see third image, always from exposed tree roots, in this case those of Thuja plicata (have also seen them grow from Madrone and decaying sword fern central root balls.)

Spore deposit white. Cap 2.3 - 4 cm across, not hygrophanous. Stipe 2.2 - 2.7 cm long x 3 - 6 mm thick, white rhizomorphs dense at the base. Odor slightly grassy. Taste mild, leaving a slight lingering astringent sensation. Gills up to 3.5 mm tall, most 2 - 3 mm. Spores inamyloid, elliptic, smooth, (4.4) 4.43 - 4.9 (5.1) x (2.6) 2.7 - 3 (3.4) µm. Q = 1.55 - 1.7. Although I'm not an expert, I believe the pileus pigment is intracellular. Could also be Clitocybe ramigena due to the shorter stipe and darker gills, but I chose R. pruinosa due to the cap color, odor, and intracellular pileus pigmentation (versus pigment in slightly thickened hyphae walls or very finely encrusted hyphae). These were growing in a Sitka Spruce/Douglas Fir forest.

Growing under Quercus agrifolia; seems to almost match the description of Russula olivacea in Mushrooms of the Redwood Coast, except that they were growing under Oaks and were medium to small size. It's a bit difficult to tell in these photos, but they had both pale green (mostly concentrated on the discs) and pale purple tones (mostly concentrated around the margins). After handling there was some grayish-brown discolorations on some of the stipes.

FDS-CA-00713
Reinhardt Redwood Regional Park, Pinehurst Staging Area- EBRPD. Baccharis pilularis, Eriogonum fasciculatum, Frangula californica, Umbellularia californica and Quercus agrifolia dominated CA chaparral and woodlands
Growing directly from Pseudotaxiphyllum moss on the base of Umbellularia californica
Benign looking white to brown mushroom with widely spaced beige lamellae and a darker brown thin stipe studded with very fine hairs, disappearing in age. Cap hygrophanous

Smell indistinct

Brought to 2019 LAMS Fair. Sequenced by Rick Kerrigan:

“Your specimen of the unusual dark-capped species (from a fair or table or ... earlier this year) is in fact what was suspected as the leading candidate: the undescribed CA species that may be Australasian, or related to that ‘megalocarpus group’ but a separate species.”

GQ_2019 in the phylogenetic tree.

Burned Quercus/Pinus dominant woodland (now shrubland post-burn), just west of Knoxville road near Lake Berryessa
Growing in soil and directly off fine roots in a hole leftover from a burned out root system
Brown pileus with a wavy margin. Lamellae white to cream colored, anastomosing, subdistant to distant, broadly attached to subdecurrent. Stipe short, fibrous, off-center
Smell indistinct

Growing in mixed conifer forest under a yew tree. Pileus matte, powdery lipstick-brick red, with raggedy white veil tissue at margin. Lamellae reddish pink, free. Stripe fibrous, reddish with white scales, bruising dark red easily. K+ black, smell indistinct

Another long term brainworm genus+species - upon digging through the literature, realizing that this is a long and winding wormhole…. This collection was fruiting abundantly throughout the interior of this soggy hardwood (likely Tan Oak) log. At first glance they remind me of shorter, skinnier, hairier, yellowish brown toned Henningsomyces. Some fruitbodies have a cone shape instead of being straight-sided tubes - this is easiest to spot in the largest fruitbody in the photo 1. The white fuzz visible in the first photo was covering the subsection I eventually photographed.

Macro Summary:
Receptacles sessile to short-stipitate, pale honey-yellow color, scattered to closely gregarious, 0.25—1.5 mm. high, 0.25mm-ish in diameter, tubular to narrowly cup or cone shaped, finely fibrillose with pale honey yellow appressed hairs (see photo 5); without subiculum; hymenophore appearing smooth white (see photo 4); margin white or paler than rest of fruitbody; Odor: indistinct; did not taste: milk none observed (water stuck in the tube may appear to be milk but it is not); did not check chemical changes; Spore Deposit: ??

Micro Summary:
Did not succeed in getting a spore print or a slide where the hairs were not overwhelming the basidia and spores – poss elliptical spores, but hard to say or measure with confidence. Hairs unbranched, thick-walled, brown and finely encrusted over their entire lengths (see photo 7) - therefore leaning Maireina rather than Merismodes (see Zibarova below).
