Astrothelium bivelum is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. [1] Found in Brazil, it was formally described as a new species in 2016 by lichenologists André Aptroot and Marcela Cáceres. The type specimen was collected by the authors in the Parque Natural Municipal de Porto Velho ( Porto Velho, Rondônia), in a primary rainforest. The lichen has a smooth and somewhat shiny, ochraceous-green thallus with a 0.4 cm-wide rough and irregular prothallus; the thallus covers areas of up to 3 cm (1.2 in) in diameter. The presence of the lichen does not induce the formation of galls in the host. The ascomata are pear-shaped (pyriform), measure 0.5–0.7 mm in diameter, typically aggregate in groups of two to six, and are usually immersed in the bark tissue. [2] The characteristics that distinguish it from other members of Astrothelium include the diffusely pseudostromatic, erumpent ascomata that are covered by thallus and have an external pink pigment, with each containing a single group of fused ascomata; and the 5- septate ascospores. [3] A. bivelum is one of the few Astrothelium-like species with 5-septate ascospores that does not contain lichexanthone. [2]
