Growing in our office. Maybe this doesn't count since it's captive...
On bark of Monterey Cypress. Thallus C+R. Spores halonate, becoming brown, 7-8 celled. ~23-28µm x 6.5µm.
First occurance in southern California since 1885. J-Dar also found one in Santa Barbara area.
Most beautiful iridescence I have found to date in this species!
On soil in serpentine prairie
Found by @samzanita at the base of a blade of grass on the underside of a log. Same specimen as this observation https://www.inaturalist.org/observations/199743127
The specimen was collected by Nate Dube and will be examined by them under higher magnification.
It was actively raining that day hence the shiny wet surface of the specimen.
This is throwing me. Doesn't seem quite like Ramalina, Bryoria, or Alectoria, at lease based on photo comparisons. Growing in small tufts among the Trentepohlia on cypress branches. Actually Ramalina thrausta looks pretty close, but it's out of range...
Growing on a well decayed Quercus agrifolia log.
Thanks to Evelyn Chea for showing me the location - it's the same log from https://www.inaturalist.org/observations/195513390
Color is accurate, an astonishing yellow green.
With the slime mold Metatrichia vesparia
curly leaf redwood (somatic mutation in basal sprouts)
lichenicolous fungi on Solorina crocea
Third photo is when found in the woods; second photo is an hour later in the woods. First photo photographed in my home studio using a 10x microscope objective adapted to my camera.
In wood chip landscaping. Mild mushroom odor and flavor. Cap extremely viscid!
Spores measure
(6.9) 7.2 - 8 (9) × (3.8) 4.1 - 4.7 (4.8) x (3.6) 3.9 - 4.4 (4.5) µm
Q = (1.6) 1.64 - 1.87 (1.9) ; N = 30
Me = 7.7 × 4.4 µm ; Qe = 1.7
An unusual find -- the two Didymium are growing atop some maturing Physarum. See the second photo for the insides of another of the Physarum fruiting bodies that was originally in front, and I opened it to see what it was.
Found by @EthanSaso. His observation is at https://www.inaturalist.org/observations/151887228

Simon, A., Goward, T., Di Meglio, J., Dillman, K., Spribille, T., & Goffinet, B. (2018). Sticta torii sp. nov., a remarkable lichen of high conservation priority from northwestern North America. Graphis Scripta, 30(6).
Growing on a moth pupae that was in the bark of a hardwood log.
On a west-facing dolomite cliff. Thickly covering parts of the inaccessible rock face
Found on dry woody material on the underside of large bryophyte-covered log. Melaleuca swamp forest.
Found on inside of bark from Douglas Fir (Pseudotsuga menziesii). The field of view is about 2mm wide. One day later the egg cases are grayer.
Small wasp found amongst a group of mature Lamproderma gracile (slime moulds).
Big pile of tailings. Lots of these in this area.
Snorkeling.
Numerous black ascomata on a dead twig, about 300 microns in diameter. Sections show a hymenium partitioned by dark columns and numerous asymmetric hyaline spores that are unisepate and about 18-20 x 7-8 microns, eight per ascus. I did not see any clear-cut photobionts, so I am now thinking this is a non-lichenized ascomycete? In addition to this dominant finding, I'm also seeing some more elongated multiseptate spores or conidia. When I section the whitish dead wood layer looking for photobionts, I found chains and clumps of rounded 8-10 micron brown spores (?).
Snorkeling.
SO MUCH of this. A surreal landscape of lumpy furry boulders.
Found on a small stick that had fallen on 'big tree' log.
Scattered fruiting bodies on live Blechnum nudum.

microscopy:
conidial mature spores round and ~ 4-4.5 µm in diameter
I am a photographer and I saw this animal at the parking lot in Fort Funston in San Francisco yesterday. It was small, the body (without the tail) maybe six inches in length at most, it seemed that it might be a juvenile? It was hiding from ravens under the cars, the ravens were very interested in it. It ran under that wooden walkway that leads to the lookout platform on the cliff. I posted the few photos that I had managed to take of it on Facebook and someone commented with an article about a sighting of one of these in the Presidio in May 2022. iNaturalist was mentioned in the article - so I'm posting one of the pics of it here.
Possibly C. laeticolor, but MD provides so many alternatives that seem to be distinguishable only by the spores that I can't really be sure.
Third photo shows the lack of a KOH reaction. Under Kunzea robusta.
Excited to find these today. 3 days ago the Gambel leaves were barely showing and today I found these stem galls
