Collection location: Matinha de Queluz, Sintra, Portugal [Click for map]

Who: zaca

No specimen available

Notes:
Growing on a wall made of cement and many pieces of rock, some with big dimensions.
In the field it looked much like a Lecanora; However, the small sized apothecia and the evolution with age of the thalline margin make me suspected of a Rinodina, which in fact it is. According to my experience of this genus in recent years (see, for instance, the comments of observation 204088), I suspect that R. beccariana is the best name for it. However, it should be noted that these specimens do not have crenulate margins of the apothecia discs, which a feature commonly referred for this species.
