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" [http://www.pbase.com/cvcc/image/58989351&gcmd=add_comment] [http://www.bioimages.org.uk/html/R155469.HTM] [http://nzfungi.landcareresearch.co.nz/html/data_photo.asp?ID=33-WNN-95&name=Lichenomphalia~alpina&NAMEPKey=33386] (including former members of "Omphalina" or "Gerronema") and the clavaroid genus "Multiclavula" [http://www.lichen.com/bigpix/Mcorynoides.html] [http://cs.wikipedia.org/wiki/Tu%C5%BEnatka_slizk%C3%A1] . Several lichenized genera occur in tropical regions, the most common being the foliose "Dictyonema" [http://www.fieldmuseum.org/research_collections/botany/botany_sites/ticolichen/images.html] . Previously basidiolichens had been classified in their own subclass, Basidiolichenes. Molecular based phylogeny does not support classification of the genera together.
