Basidiolichen

Basidiolichens are lichenized members of the division Basidiomycota within the subkingdom Dikarya of the kingdom Fungi. They form a diverse yet much smaller group of lichens than the far more common ascolichens of the division Ascomycota.^[1] Owing to how few described species there are, basidiolichens are generally considered to be poorly researched, and few studies that characterize their natural products exist. Biogeographically, basidiolichen species may be distributed in a cosmopolitan manner or more regionally, ranging from arctic and montane habitats to more temperate and tropical environments. Morphologically, basidiocarp (fruiting body) and thallus (vegetative tissue) structures may vary widely within and between basidiolichen genera.^[2]
