Anacystis magnifica sp. nov.

PliATE 4, FIGURE 38

Colonies spherical to subspherical, free, 80-125m (up
175 m) diam.; cells angular, irregular in shape and size, 11-15 p
diam., bright aeruginous, not densely crowded together, coarsely
granular; resting spores 18-22 m (up to 30 m) diam., of the same
shape as the cells, with a thick, hyaline wall closely beset with
hyaline spines about 6 n long, teguments firm, homogeneous
throughout the colony, hyaline, 7-12 n thick outside of the colony
of cells.

Growing in association with other Myxophyceae, on a w^all in
Fort San Cristobal, San Juan, no. 2016 a, type; on a wrater pipe
near a stream at Maricao, no. 1148 c.

Anacystis magnifica is one member of the group of the genus
in wrhicli the resting spores are much larger than the vegetative
fcells from which they arise, and it has more or less highly ornate
spore walls. The white spines remain on as remnants until the
new colony arising from the resting cells has attained almost
half the mature size, but they disappear very gradually. At ma-
turity no trace of them is to be seen on the limiting membrane.
