Lejeunia Gerlach 1961
"LEJEUNIA" Gerlach, 1961, p.169. Emendations: Kjellström, 1972, p.467, Lentin and Williams, 1976, p.68–69 and Bujak in Bujak et al., 1980, p.68, all as Lejeunia — however, see Head (1993, p.30–31). Name illegitimate — senior homonym: Lejeunea Libert, 1820. Substitute name: Lejeunecysta. Originally Lejeunia Gerlach, 1961 (generic name illegitimate), subsequently (and now) Lejeunecysta, thirdly Protoperidinium subgenus Protoperidinium section Lejeunecysta (section name not validly published). Taxonomic senior synonym: Quinquecuspis, by implication in Matsuoka (1987, p.57), who incorrectly considered Lejeunecysta to be the senior name — however, this synonymy has not been generally followed. Type: Gerlach, 1961, pl.26, figs.10–11, as Lejeunia hyalina.
