Hassalia hsterogenea sp. nov.

Plate 19, figure 42

Filaments very short, much contorted. with smooth, . ‘Title
curves, moderately branched, about equally single and gc mate
branching, soon recurving, 13-16n cliam.; trichomes 9.5-13 }i
diam., not constricted at the dissepiments,'or only moderately so
in part; cells quadrate in the older parts, ono-half to one-fourth
as long as the diameter at the apices, pale aeruginous, homo-
geneous; heterocysts of the same shape and size as the contigu-
ous cells; not abundant; sheath close-fitting, thin, homogeneous,
dark brown.

Growing on rocks at Hacienda Holm, Mayagiiez, no, 1191,
type; on lava rock at Coamo Springs, nos. 1023 a and 1921.

1 The above-described species might be almost equally well
placed in either Scytonema or Hassalia. On account of its di-
minutive size and short branches I have placed it in the latter
genus.
