Kantvilas, G. 2010. Acanthothecis virgulicola, a new Tasmanian lichen. — Herzogia 23: 9–13.
Acanthothecis virgulicola from the cool temperate rainforests of Tasmania is described. The new species is characterised by the presence of stictic acid and by its almost exclusively transversely septate ascospores. It is compared briefly to other species in the genus, especially A. gyridia (Stirt.) A.W.Archer, which also occurs in Tasmania.
