What is "typhula"

Typhula is a genus of clavarioid fungi in the order Agaricales. Species of Typhula are saprotrophic, mostly decomposing leaves, twigs, and herbaceous material. Basidiocarps (fruit bodies) are club-shaped or narrowly cylindrical and are simple (not branched), often arising from sclerotia. The anamorphic genus Sclerotium is (in its modern sense) a synonym of Typhula. A few species are facultative plant pathogens, causing a number of commercially important crop and turfgrass diseases.
