Growing on mixed conifer leaf litter in riparian forest. Pileus light tan, ornamented in cinamon-brown dusty looking scales, colored like a snickerdoodle; often dimpled in the center and irregularly wavy at margins in typical omphalinoid fashion. Gills wavy, some shallowly crossveined, deeply decurrent. Stipe whitish at apex, fading to pinkish brown at the base.

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

Growing under a log in Hesperocyparis sargentii forest. Small mushroom, squashed from growing in tight quarters. Cap grey and purple, pruinose. Lamellae an interesting key lime pie green. Stipe reddish purple, twisted and bent.

This was first seen by @smellyturkey who's observation you can see here: https://www.inaturalist.org/observations/200154535

I think I saw this species last year:
https://www.inaturalist.org/observations/154667088

Habitat: Moss (Most likely Brachythecium or some similar pleurocarp) growing in a shaded wall of concrete.

Most fruiting bodies are less than a cm and have basal mycelium on the moss.

The first microscopy photo is in Melzer's reagent and the second in KOH.

Currently spores seem to grow and germinate in culture.

1 small fruit body was sequenced, but does not match the previous sequence obtained for this species. I'm inclined to think that the original sequence was contaminated as it was taken from a not so clean culture. I will update this with additional culture and fruitbody sequences. That being said, I will not upload this to genbank until I know for certain that the sequence read is good.

On another note hopefully I can find this again or can get multiple collections of this. I'll have to check the spot from last year.

If new sequences keep coming back as novel and I can't find anything in the literature I will take a crack at describing this as a new species (So long as I can get more than just ITS)

Montane Entalomatoid growing in moist soil along trail edge, no overstory plants in the area.

Similar to a @corndog observation in a similar, nearby locality and comparable elevation: https://www.inaturalist.org/observations/183896554
and another collection of mine in Snoqualmie pass:
https://www.inaturalist.org/observations/184817852

Sample sent to @relg (Ariel Goldsztejn) 12/4/2023

Caps 1 cm diameter, 1.5 cm tall. Growing from the soil walls of subalpine meadow trail cuts with short but steep 20cm soil edges, ~5.750 ft elevation, presumably same species as https://www.inaturalist.org/observations/171323950 made nearby on the same day

Acomycete growing from decaying graminoid material in an area with Carex utriculata and Scirpus microcarpus. Growing gregariously over several square yards in a seasonally flooded area of a montane acidic fen peatland. @corndog has a Genus/Species concept for this and will likely be making another observation for these from this locality, I will link these observations when available

appears to be growing on Willow in all three sticks to my eye, these would be quite dark and somewhat large for Cudoniella . Growing in flowing water from a seep into a pond under Willow, Sugar pine, Pacific silver fir and Spirea

Douglas-fir, western redcedar, rhododendron.

Scattered somewhat widely, frbs appearing “independent”.

No smell detected.

Cap and gill tissue a bit tough and elastic.

ITS: Sequenced by the Matheny Lab

On Suillus ponderosus (presumably) which was fruiting right next to it and nearby in abundance. Does not look like any Hypomyces chrysospermus I have seen. Very carpet-y and pronounced fuzz, not just powdery. Saved some for sequencing.
