Plumularia floridana Nutting, 1900: 59 , pl. 2 figs 4–5.— Calder, 1983: 20, fig. 11.— Migotto, 1996: 55, fig. 10D–F. Plumularia pennycuikae Millard & Bouillon, 1973: 85 , fig. 10N–P.—Millard, 1975: 398, fig. 126A–C.— Calder, 1997: 15, fig. 3.— Ansín Agís et al., 2001: 234, fig. 90.

Material examined. Stn. 6: 28.03.2008 —a dense, fertile colony, ca. 8 mm high, on Thalassia testudinum .

Type locality. Vicinity of Cape Romano, Florida, United States.

Remarks. The present fertile material is easily identifiable due to the peculiar gonothecae, which arise from the axil of cauline internodes and are small, ovoid to nearly spherical, and covered by a filmy perisarc layer. For detailed descriptions of this species, see Migotto (1996) and Calder (1997).

Distribution. Circumglobal. Extensive data on the previous records are available in Ansín Agís et al. (2001). The Caribbean records are summarized by Calder & Kirkendale (2005).
