Taxonomy edit

The genus was circumscribed in 2008 by lichenologists André Aptroot and Laurens Sparrius, with Angiactis littoralis assigned as the type species. This lichen was originally described as a species of Lecanographa by Gintaras Kantvilas. The genus name Angiactis derives from the Greek αγγείο ("receptacle") and αὐτός ("shaped"), and refers to the thalline excipulum that covers the fruiting bodies.[2]

Description edit

Angiactis species have a thalline exciple (rim), but lack a cortex. Their asci are of the Grumulosa-type, and the ascospores are hyaline, with thick walls. The excipulum is carbonized (blackened) and does not have any reaction with a KOH solution.[2]
