Nemania was erected for a heterogeneous assemblage of taxa by Gray (1821). Subsequently, Nemania was emended and reinstated by Pouzar (1985) to accommodate the Hypoxylon selpenscomplex of Hypoxylon subsection Prinocinerea of Miller (1961). As emended by Pouzar (1985) Nemania species develop superficial stromata, lacking both a subiculum and bright pigments that 160 are soluble in KOH, and also possess a J+ or J-, rectangular apical apparatus that is higher than it is broad. The apical ring is more similar to those of Kretzschmaria and Xylaria than those of Hypoxylon (Pouzar 1985, Smith & Hyde 2001)
Type species: Nemania maritima Y.M. Ju & J.D. Rogers, Nova Hedwigia 74(1-2): 102 (2002).
Other accepted species: Species Fungorum – search Nemania.
