Basidiolichen
Basidiolichens are lichenized members of the Basidiomycota, a much smaller group of lichens than the far more common ascolichens in the Ascomycota. In arctic, alpine, and temperate forests, the most common basidiolichens are in the agaric genus Lichenomphalia and the clavarioid genus Multiclavula. Several lichenized genera occur in tropical regions, the most common being the foliose Dictyonema. Previously basidiolichens had been classified in their own subclass, Basidiolichenes. Molecular based phylogeny does not support classification of the genera together.
