Rhodotorula genus, but unsure which species? This culture grew on a rose bengal plate after exposure for 4 hours in a bathroom shower. It’s pink and unicellular, took about a week and some change for colonies to form. Most recent photo was on dextrose with antibiotics
The cap has an interesting crunchy texture.
Growing on well decayed wood.
Spores smooth, inequilateral, 10.5 – 13 × 5 – 6.5 µm, with 1 or 2 oil droplets per spore. 8 spores per ascus. Asci walls invisible in KOH.
Spore measurements:
10.6 [11.4 ; 12] 12.8 × 4.8 [5.5 ; 6] 6.6 µm
Q = 1.7 [2 ; 2.2] 2.4 ; N = 15 ; C = 95%
Me = 11.7 × 5.7 µm ; Qe = 2.1
This tiny, striking Xylaria species, with its nearly naked perithecia, has become the poster child for Xylariaceae research in Los Cedros. Roo and I thought they looked a bit like these in cross section:
These are Kodama, the forest spirits of Japanese folklore, as portrayed by Hayao Miyazaki in his epic 1997 film, Princess Mononoke.
This is likely the first record of X. tucumanensis from anywhere outside Argentina, and as such, significantly extends the species’ known range.

Substrate: corticate standing dead wood (post), ~3 cm diam (same as Observation 264296)
Habitat: Northwest Andean montane forest (NT0145)
Collector(s): D. Newman & R. Vandegrift
Collection #: RLC1378
Photomicrography and molecular data forthcoming
Found by my friend @graysquirrel
Lower magnification shots from the previous day show the characteristic nodding heads.
@johnstonp Here are additional photos of this tiny beautiful Asco.
Found by @cath_marciniak-stephen_axford.
Host: Betula nigra
Smooth diatrypous fruit body, very thin - like a single celled layer with no clear body.
No asci observed, possibly anamorphic.
Spores dyed in lactophenol cotton blue - only staining the apical segments
Found by @graysquirrel on decomposing conifer wood.
The sporocarps are about 0.4mm in diameter.
Found under Ganoderma.
@Warren_Cardimona collected the sample for sequencing.
Good discussion of this genus at https://www.mycoguide.com/guide/fungi/asco/sord/hypo/hypo/spor
Found by @greysquirrel in Chaparral area
A fun Physarum find -- a Physarum donut spotted by @EthanSaso while we were looking in eucalyptus litter in Golden Gate Park. It was on a tiny twig, with one other fruiting body. The area was full of Physarum bitectum and Physarum bivalve; this is one of those species.
Note the Springtail on the frogs eye
Found by my friend @debk

First two photos are of mature fruiting bodies, Nov 21. Third photo is immature fruiting bodies, Nov 18. Last photo is fruiting bodies just starting to form from plasmodium, as found on Nov 17 by Dennis Desjardin.
First occurrence in the western US, as far as I can tell.
Under Incense Cedar on a north-facing slope in mixed riparian zone forest.
Found by @EthanSaso. His observation is at https://www.inaturalist.org/observations/151887228
Found in fog drip saturated Sequoia sempervirens dominant coastal forest with Pseudotsuga menziesii and Notholithocarpus densiflorus understory MMWD
Growing in Sequoia sempervirens duff
Blue stiped Entolomataceae with a completely inverted cap. Lamellae grayish
Smell indistinct
Found in leafletters in a wet carrs. Accepted officially in Denmark as found no. 4 or 5.
Substrate: dark of sappy downed tree, smell of pickles and yellow latex, same as others? 5-15 cm diam
Habitat: Northwest Andean montane forest (NT0145)
Collectors: D. Newman & R. Vandegrift
Collection #: RLC1241
Photomicrography and molecular data forthcoming
Found by my friend @graysquirrel. Maximum size is only about 1/2mm in diameter for each fruiting body.
Thank you to Iryna Yatsiuk for helping with this identification of this one.
She told me that molecular studies show that this is a species-rank clade related to A.pomiformis. Similar to A. olivaceoglobosa, this id is being revised at present. We are calling it Arcyria pausiaca for the moment.

Golden-backed Frog
Mushroom grown on frog body
Found by @graysquirrel. See her observation at https://www.inaturalist.org/observations/160694737
On dead alder (I think) in a snowmelt area. Yuba pass, 2045MASL
Found by @graysquirrel in a garden in Sacramento, on redwood needles. Focus stack of 178 images using a 10x microscope objective adapted to a Sony a7r2 camera.
Near melting snow at Mt. Ashland.
Elev; 6600 ft.
2nd photo show reaction to 365nm UV light.
On Thuja snag. Stalk about 2.5mm on large fruiting body, small ones in second photo about 1mm, assuming they are the same. spores (7.6) 9.6 - 12.8 (14.6) × (4.2) 4.4 - 6.5 (7.4) µm
These were growing with Stemonitopsis hyperopta on an oak log.
Garter snake and a fan
Pretty sure these other observations are of the same infected springtail, but at different times. They were found in almost exactly the same place (within 1 inch since the last observation with no other infected springtails in sight)
Dry cap and stem
Each one of these things is only 2 or 3 millimeters long. Think they are slime mold fruiting bodies. Found on the underside of a piece of elevated rotting wood. Any further info would be appreciated.
I have seen these abundantly in snowmelt areas. This is the first time I have found them on the coast.
Growing on a pile of wood chips.
grown on an oak twig brought home from the forest (in a greenhouse)
growing in duff under spruce, less than 2 cm tall
Cultivated on blue oak in a moist chamber.
Photos 2 and 3 were taken in the morning when it was close to 0C; the first photo was taken in the evening when it was around 12C
Captured in 2018
From the herbarium of Dr. Steven Stephenson, University of Arkansas. Collected by dela Cruz and Stephenson. On twigs, lowland dipterocarp forest.
Took some dry Doug-fir bark home and added water. Voila'. Very small, only 1.5 mm
