Dear Ascofrance,
I would like to ask for your help. This is not my own find, but I am the one trying to assist a member of a mushroom identification Facebook group with identification. The asco grew in a concrete container that mixes dog feces, compost, and soil. I'm fairly sure it belongs to Pseudombrophila, but the dense, large clusters of vivid purple fruiting bodies seem a bit off from the likely merdaria species.
Spores: 10.5–12.5x7–8.5 µm (I also measured shed spores), with slight roughness visible. The paraphyses are septate, branched, and slightly swollen at the tips (snakehead-like). The excipulum appears vivid red under the microscope. Due to the clustered appearance and color, I considered P. misturae as a possibility, but the spore size doesn't seem to match. Is there perhaps another species that could fit? I also wondered if the purple color could be due to cold (frost).
Thank you in advance for your help!
