Authority: Gardner, Nathaniel L. 1927. New Myxophyceae from Porto Rico. Mem. New York Bot. Gard. 7: 1-144. pl. 1-23.
Family:Schizotrichaceae
Description:Species Description - Filaments associated with other algae, prostrate to somewhat erect, and at times slightly fasciculate, 400-800 µ long, 8-15 µ diam., moderately and alternately branched; apices acuminate, closed; trichomes 1-3, or as many as 6, within a sheath, 3.3-3.6 µ diam., straight or arcuate, with the filaments not congested, slightly constricted at the cross-walls; cells 2-2.5 times as long as broad, homogeneous to finely granular, pale aeruginous to slightly honey-colored; cross-walls thin, but conspicuous; apical cell blunt-conical; sheath homogeneous, hyaline, but soon changing to dense honey-color.

Distribution and Ecology - Growing on red soil by the road to Hacienda Catalina, Palmer, no. 776 a, type, and no. 778 a\ on rocks at Maricao, nos. 1031 a, 1033 a, 1037 c, and 10A3 a; on soil by the road to Monte Montoro, Maricao, nos. 1071 c and 1077 d; on rocks near Maricao, no. 1142; on earth at Hacienda Holm, Mayagiiez, nos. 1177 a and 1179 a.

Discussion:Schizothrix mellea, as proposed here, is very close in the structure of the trichome to Schizothrix (Symplocastrum) Friesii as described by Gomont,13 but it is much smaller (less than one millimeter long) than that species, and lacks the rigid, erect, spine-like habit which that species generally, though not always, assumes.
