Favoritos de stucumber

Fairly abundant, seemed to prefer exposed/dry/disturbed areas. Always partially exposed. Rich, complex aroma with notes of soy sauce. Purple gleba seemed to become more colorful upon initial exposure to air.

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).

The GBIF image gallery includes a herbarium slip for a P. ochracea obs from Cooke, collected in Inverness, Marin County on Coast Live Oak.

Exudate longwave UV reactive. Exudate present before disturbance. Cap sticky. Adjacent to Ceanothus crassifolius. Other species present include Salvia mellifera, Adenostoma fasciculatum, Eriogonum fasciculatum.

Growing from duff and organic matter under Ribes nevadense understory- Calocedrus decurrens, Abies and Alnus rhombifolia nearby
Near East Fork Barton Creek, San Bernardino NF
Subdecurrent gills with pale pink spore print (seen in third photo)
Farinaceous/cucumbery smell
Very bitter/chemically taste
Slightly UV reactive (hard to get photo)

F000310

Found in a CHEG zone along the banks of a very tiny stream. All four CHEG families were present within ~10ft.

Last photo has a scale bar that is calibrated at the depth of the numbered tag. That photo has been color edited so that the fruiting bodies can be better seen.

Same as obs 267941, but definitely not in moss.

No smell. Maybe the same as obs 269111.

Seems like it should be super easy to ID, but I have no clue. Same as obs 267955.

The purplish tint is accurate. Solid feel to them. Gills dried greyish.

Medium-strength pleasant cucumber smell.

ITS sequence from Brandon Matheny and Django Grootmyers.

Found two specimens ~1m apart in a large Rhododendron - one (pictured) gripping the underside of a branch and the other (not pictured) gripping the edge of a leaf. Specimens sent with João Araújo to NYBG
