Field Macewort (Mannia triandra)Observer
mossman13Description
Growing on west-facing sandstone ledges. An attempt to follow through development from previous observation, but with different individual. ID uncertain, but based on thallus color, and what seems to be a developing community consensus.

kzoebelDescription
On a large outcrop of limestone. I'm unsure if these are young versions of the same Dermatocarpon I find around here or a different species? I usually find larger, single ones, not these little clumps.

Genus TremellaObserver
mjpapayDescription
This is a purposeful duplicate observation, as the original has been hijacked by a n'er do well.
Flora of Lichenicolous Fungi, 2022, does not have mention of the genus Dermatocarpon being parasitized by a lichenicolous fungus, but does have record of a Tremella umbilicariae that parasitizes at least one species of the genus Umbilicaria.
I speculate that the protuberances on the surface of this Dermatocarpon arenosaxi are due to an infection by Tremella. [It is a starting point, an Hypothesis]. Some of the protuberances are entirely black and appear to have a surface coated in spores. In the larger bloated protuberances of the thallus of the Dermatocarpon, in some cases black spores are evident in cracks/openings.

At the center of the photo is a large mature thallus. In the field I was mistaken when I thought the protrusions on its surface were apothecia (of which I was admittedly excited). However, upon examination of the photos on the computer, I realized my mistake. But what are these protuberances? Perhaps they are manifestations of an infection by a fungus, such as Tremella. The Flora of Lichenicolous Fungi, 2022, pages 265-6, refers to a Tremella umbilicariae that infects species of Umbilicaria, of which the genus Dermatocarpon is related. However, the contents of Flora of Lichenicolous Fungi, 2022, does not include a reference to Dermatocarpon. So, at the moment Tremella is the best fit. A separate observation has been made for the Tremella : https://www.inaturalist.org/observations/193435976

Reticulate Shield (Crespoa crozalsiana)Observer
mossman13Description
Growing on lower trunk of small Pinus banksiana in open, sandy mixed woodland. ID uncertain, but based on scrobiculate upper thallus with what seem to be a small amount of developing pseudocyphellae and soredia, and with rounded brownish lobe tips, but something about the upper surface seems odd, and also the black underside is definitely weird.

Limestone outcrop on north facing slope, not far from the river. The surface it was growing on was mostly quartz, so it seems like a mostly siliceous substrate. Maple-basswood forest with remnant white pine and Canada yew.

These patches of jelly lichens growing above and below a patch of moss were found on a shaded wash cut along Hellhole Canyon. The first photo is how they looked when I found them. The second is them several minutes after being hydrated, and the third is a close up of the expanded lichen.
