Josphine E. Tilden. American Algae.

272. Conferva major (Kg.) Rabenh.forma ferruginea Tilden. Observations
on some West American Thermal Algse. Bot. Gaz. 25: 91, 92. pi. 8.
f. 6-8. F 1898.

Brownish (ferrugineus, fulvus); encrusted with ferric-oxide (Fe 203),
sometimes in narrow bands,generally forming extensive coatings; cells
13-20 mic. in diameter, twice the diameter in length, after division
equalling the diameter.

In acid waters of overflow. Temperature 734° C.

Echirus Geyser, Yellowstone National Park.

Coll. W. H. Weed, 1897.

The width of the filament in the form is somewhat narrower than those
of the species. The specimen shows well the “letter H” appearance of
UM ~o^Xthe ruptured membrane which De Toni makes a generic character.
