Taxonomy
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.[3]

Description
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.[3]
Species
As of July 2024[update], Species Fungorum (in the Catalogue of Life) accepts four species of Angiactis:[2]
