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 genera Lichenomphalia[1][2][3] (including former members of Omphalina or Gerronema) and the clavaroid genus Multiclavula[4][5]. Several lichenized genera occur in tropical regions, the most common being the foliose Dictyonema[6]. Previously basidiolichens had been classified in their own subclass, Basidiolichenes. Molecular based phylogeny does not support classification of the genera together.
