Exsic.: Musc. Amer. St. Merid. 161 (as Jungermannia Sphagni) Musc. 
Alleg. 228 (as Jungermannia Sphagni, var. 1); Hep. Bor.-Amer. 61 (as 
Cdatcchidnn Sphagni); Hep. Amer. 36 (also as O. Sphagni); C. Wright’s 
‘p. Cubenses, without number (as Sphagnoecetis prostrata). 
Very similar in appearance to O. prostratum are sterile speci- 
mens of Jamesoniella autumnalis (DC.) Steph. (=/ungermannia 
Schradert Mart.), and the two species are often confused in her- 
baria, both being referred to O. Sphagni. J. autumnalis com- 
monly grows on decayed logs, but is sometimes found on shaded 
banks or on rocks.. It has succubous undivided leaves and is 
of about the same size as O. Sphagni. It is, however, quite des- 
titute of flagella; its leaves are not distinctly bordered, and its 
leaf-cells are slightly larger, averaging 21 in the middle of the 
leaf and 28y at the base. Of course, fruiting specimens of the 
Jamesoniella are very distinct, the perianth being terminal on a 
leading branch.
