Isolates of Gibberella baccata (= Fusarium lateritium) were mated and produced perithecia on carrot agar at 22 C under mixed cool-white and black fluorescent lights on a 12-hr alternating light/dark schedule. Of the cross-fertile isolates, most were hermaphrodites, although three were males and one was tentatively identified as a female. Data from test crosses indicated that the two compatibility groups were allelomorphs not linked to the gene(s) controlling sexual expression. Isolates proved interfertile irrespective of origin and host.
