Vernacular names
Angiactis is a genus of crustose lichens of uncertain familial placement in the order Arthoniales.[1] It has four species.[2]
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, Species Fungorum (in the Catalogue of Life) accepts four species of Angiactis:[2]
Angiactis banksiae (Müll.Arg.) Kantvilas & Stajsic (2020)[4]
Angiactis bermudensis LaGreca (2008) – Bermuda
Angiactis littoralis (Kantvilas) Aptroot & Sparrius (2008) – Australia
Angiactis spinicola Aptroot & Sparrius (2008) – Galápagos
