Importance and distribution

There are 46 Anisomeridium epithets in Index Fungorum (2022), but several species have been transferred to Megalotremis and Pleurotrema. Anisomeridium comprises 60 species known on semi-aquatic and aquatic rhyolite, on bark, lime plaster, on leaves in rainforest, smooth bark in undisturbed forest, living branch of Andromeda ligustrina (Ericaceae), leaves in lowland rain-forest, lateritic rock in primary rainforest and Musci (Pottiaceae). Species of Anisomeridium are lichenized and able of supporting photosynthesis (Will-wolf et al. 2004). Anisomeridium is reported from Africa (Ivory Coast), Asia (India), Australia (New South Wales), Central America (Costa Rica), Europe (Portugal), North America (The United States) and South America (Brazil).
