Abstract From an analysis of Link's accounts of Antennaria and its type species, A. ericophila, it is concluded that the current usage of Antennularia (= Antennaria Link non Gaertner) for such species as Venturia straussii Sacc. and Roum. is untenable. The history of Antennaria and its nomenclatural variants indicates that these names have been applied to Sphaeropsidales, to Dematiaceae, Stil-baceae, and Mycelia sterilia amongst the Hyphomycetales, and also to different genera of Pyrenomycetes. Because of this background of uncertainty and the impossibility of typifying the name of the species, for the type collection is missing and no spore form was defined in the accounts by Link, it is considered best to regard Antennaria as a nomen amhiguiim and A. ericophila as a nomen dttbium.Antennaria pinophila Noes is lectotypified by one of two specimens named by Nees. This second species of Antennaria, from central Europe, is emended so that the name refers to the phragmoconidial state. Two other components of the lectotype collection, as well as the diagnosis, are referred respectively to Capnobotrys neesii n. gen. and n. sp., and to Tripospermum.Antennatula Fr. ex Strauss, type sp. Antennaria pinophila, is an earlier name for Hormisciella Bat., type sp. H. atra Bat. from Brazil. Hyphosoma Syd., type sp. H. hypoxyloides Syd., from New Zealand is considered to be a nomen confusum.
