Order Bryopsidales
Family Bryopsidaceae
Bryopsis pusilla Levring 1938: 11-13
Plants green, forming dense turf up to about 1 cm tall; entangled basal system of horizontal rhizoids giving rise to usually unbranched erect siphons 0.4 – 1 cm high and 250-400 µm thick; branching rare, distichous, branchlets up to 1.5 mm long, 90-160 µm thick, all branchlets reaching beyond apex of main siphon to impart brush-like appearance.
Collections, ecology and regional distribution
Recorded from Port Elizabeth to northern KZN (36-58) but may be distributed further westward, as several specimens tentatively identified as B. pusilla have been collected from False Bay and Cape Agulhas (BOL). Found in the lower eulittoral, generally in sand-binding turfs. Levring (1938) records that it occurs in a short Corallina turf.
Worldwide distribution: also found in Mozambique (Silva et al. 1996).
Type locality: Port Elizabeth, Eastern Cape (Silva et al. 1996).
Note: Levring (1938) distinguishes this from other Bryopsis species on the basis of its smallness and growth form with a well-developed and interwoven horizontal system of rhizoids.
