           Index Fungorum number: IF 478577; Facesoffungi number: FoF11847, Fig. 1

Fig. 1 Abrothallus spp. (re-drawn from Fig. 1 in Suija et al. 2018). a Paraphyses of A. parmeliarum. b Mature ascus with mature ascospores. c Ascospore with one septum in A. bertianus. d Ascospore with three septa in A. suecicus. e Ascospores divided into two part-spores in A. secedens. f Surface view of pycnidia of A. bertianus on the thallus of Melanelixia fuliginosa. g Conidiospores of A. bertianus. Scale bars: ae = 5 μm, b, g = 10 μm, f = 100 μm.

Importance and distribution

Species of Abrothallus are lichenicolous and form obligate associations with lichens either as saprotrophs that inhabit dead lichen thalli, or parasites that acquire fixed carbon from living lichen hosts (Hawksworth 1982, Lawrey and Diederich 2003).

 

There are 68 Abrothallus epithets in Index Fungorum (2022), but several species have been transferred to Arthonia, Bachmanniomyces, Clypeococcum, Karschia, Micarea, Punctelia, Sclerococcum, Sphaerellothecium, Taeniolella and Tetramelas. Abrothallus is found on wide range of host such as Fraxinus sp. (Oleaceae), Parmelia sp. (Parmeliaceae), Platismatia glauca (Parmeliaceae), Ramalina calicaris (Ramalinaceae), Sticta sp. (Lobariaceae) and Usnea sp. (Parmeliaceae). Abrothallus is reported from Africa (Seychelles), Asia (Russia (Krasnoyarsk)), Australia (Tasmania), Europe (Canary Island, Germany, Luxembourg, Portugal, United Kingdom), South America (Colombia, Peru) and the United States (Florida, North Carolina). A revision of Abrothallus must be carried out as several species lack molecular data.
