Notes:
It took sometime but at the end I think to have reached the right classification for this one. Let’s hope so.
The specimen grew on the soil, has a squamulose thallus with perithecia immersed in the squamules. The brown-redish squamules of approximate size of 7 mm are mostly more or less roundish, some more elongated, and have at the margins abundant black globose pycnidia. These features lead me to the species Placidium lachneum, though I didn’t observe the spores, using the key and the description of this species in the British Flora. I also saw the photos in Sharnoff photos and found them very similar to those of my specimen.
