Notes: Deja vu: Looking to the specimen I thought it could be a Peltigera. However, no rhizines were found. Looking for other stuctures in the underside, no cyphellae or pseudocyphellae were there, thus eliminating Sticta, although some pubescence existed in some zones. Spot tests performed, first in thallus with unclear results, some C+ brownish and K+ weak yellow, and after scratching a bit and a K-purple reaction (due to anthraquinones) appeared in medulla.
Searching for information in the internet for the genus Nephroma, as an alternative to the previous mentioned genera, I came to the page of “Irish lichens” for the species Nephroma laevigatum, were all the characteristics seem to match.
This specimen had no apothecia. Later on at the same zone I found one fertile specimen, that will be considered in a different observation.
