596. Oscillatoria min nesotensis n. sp.
Stratum thin, dark aeruginous; trichomes more or less curved, especially
,	constricted at joints, 2.5 mic. in diameter, with straight or slightly bent
apex, neither attenuate nor capitate; pseudocysts in general quadrate, 2-4
mic. long; protoplasm homogeneous; dissepiments pellucid; apical pseud-
ocyst rotund; no calyptra.
On sides of stone quarry under dripping water.
Near University campus, Minneapolis, Minn.
Coll. Miss Gene Lilley 27 F 1902.
The plant differs from O. geminata in the length of the pseudocysts, in tht
absence of granules, and! in its habitat. Like that species also, it resembles a
Phormidiiim, but the trichomes when examined were oscillating rapidly thus
\
. showing conclusively that it was an Oscillatoria.
