Observations by sbenson

On serpentine, often making a rusty halo on the rock surface; thallus rimose-areolate, thin, endolithic; apothecia +/-submerged in thallus, w/o proper margin (photos 3 & 4); epihymenium blue-green; hymenium dense-gelatinous--preventing view of asci, squash mount didn't release any spores. Hypothecium dark. Photo 5 shoes an ascus to the right of the scale bar--looks more like oil bodies than spores inside of it.

On limestone rock (see last photo for habitat--growing on the gray colored outcrop.

Small, brown jelly lichen with white tufts of tomentum on lower surface (photo 4), isidia-like warts on upper surface, apothecia disks reddish-brown. Lobe tips rather thick and round. The thallus swells when wet: photo 2 dry, photo 3 wet.
Spores muriform, keys say 3 transverse septa and 1 longitudinal--I found more variation (see sketches in photo 6). Spore size matches keys.

On bark of sargent cypress. Black, dense cushion-like mounds of minute chain-like strands.

Second collection made September 9, 2023. Found some reproductive structures (conidia?) [see photos 3-5]
Spores brown elliptical and slightly pointed at ends, brown, 3-septate, 154 x 51-62 microns.
