Porina gryseelsiana

Porina gryseelsiana is a species of foliicolous lichen belonging to the family Porinaceae. It was discovered in Orientale Province, in the Democratic Republic of the Congo on the leaves of understorey plants in a tropical rainforest. It was subsequently described as new to science in 2014. It is a rare species which is only known from this one collection.

It resembles Porina octomera in appearance but can be differed from it by its orange-brown perithecia and larger spores. The photobiont of this species is the green alga Phycopeltis.
