Plectonema murale sp. nov.

Plate 9, figure 89

Filaments much contorted and geniculate, 3.6-4 n diam.,
branching sparse; trichomes 1.5-1.8 m diam., slightly constricted
at the cross-walls, not attenuated at the apices ; cells pale aerugi-
nous, quadrate to 2 times as long as the diameter; apical cell
blunt.

Growing on the wall of a bridge, Juan Martin, Fajardo, no.
732 c, type.

The material appears to have come nearly to the end of a
period of growth as the branching is decidedly sparse, and most
of the old connecting sheaths have disintegrated. The genicu-
late character of the filaments would indicate that branching was
abundant, and more or less perpendicular to the main axis.
