On mosses on an eroding, sandy roadcut.
Ascospores 6-celled, warty (photo 2 - 1,000x in water)
WDV 559
Two cm colony on moss on soil layer over rock, beside the stream. The reflected colour of the sky is a bit deceptive; the thallus is translucent green-black. Thickened, often ascending margins. No isidia or apothecia. There is occasional white tomentum to affix it to the moss.
