No specimen available

Identification: This lichen seems to belong to a cluster of lichens containing Melanohalea halei, M. olivacea, and M. septentrionalis. The apothecia are cup-like and confined to the center of the thallus, so it is not M. septentrionalis, and the surfaces of the lobes are sprinkled with “white, punctate pseudocyphellae” and tiny “conical papillae” (Hinds and Hinds, 2007, p.306), indicating that it is likely M. olivacea rather than M. halei.

The lichens in the formerly more inclusive genus Melanelia s. lat. are now distributed among Melanelixia, Melanohalea, and a reduced Melanelia s. str. (Esslinger checklist #14, 08 Oct 2008). At the moment our database is carrying the 12 species of Melanohalea and the 7 species of Melanelixia as well as their synonyms in Melanelia.

Common name: spotted brown-shield
