Josephine E. Tilden. American Algae.

274. Microspora amoena (Kg.) Rabenh. forma thermalis Tilden. Observa-
tions on some West American Thermal Algae. Bot. Gaz. 25: 92, 93.
pi. 8. f. 12. F 1898.

Dark green, stringy; cells cylindrical, 11-14 mic. in diameter, before
division 2-3 times as long as wide, after division equal to or a little
more than the diameter in length; membrane smooth, delicate, firm;
cell contents finely granular, bright green; filaments not constricted at
septations.

a.	Lying in overflow from spring. Temperature 41°C.

b.	In soft masses on bottom of spring. Temperature 38°C. With Pro-
tococcus botryoides forma caldarius.

Frying Pan Basin, Yellowstone National Park.

J. E. T. 7 J1 1896.

It is difficult to decide whether this plant should be classed as a Conferva or
a Microspora, as the structure of the chloroplastids could not be made
out. It is placed here provisionally. Its size is not as great as that of
the species.
