Anacystis irregularis sp. nov.

Plate 5, figure 45

Colonies very variable in shape and size, up to 75 p diam.,
closely associated into masses of considerable size, the tegu-
ments of the older colonies at times completely fusing; cells
spherical, closely crowded together, 1.8-2.5 n diam., bright aeru-
ginous, homogeneous; resting spores with a very thin, smooth,
hyaline wall; tegument close-fitting, hyaline, homogeneous
throughout the colony.

Growing among other species of Myxophyceae on the trunks
of trees, Coamo Springs, no. 300, type; on “Flytteblok” west of
Humacao, no. 577 a; on rock near Hacienda Catalina, Palmer,
no. 791 a; on lava rock by the road to Monte Montoro, Maricao,
no. 1065 d.

As this species is piled together and at times in part conflu-
ent, it resembles Kuetzing’s illustrations of Polycygtis icMh.yo-

blabe, but there is not the continuous colonial tegument, except
in part where the colonies are old, characteristic of that species.
