single, subglobose, .25-.3 mm. in diameter, the very short stalk 
of a single row of cells: 9 branches 2-10 mm. long (archegonia 
sometimes apparently terminal on the main stem), leaves increas- 
ing in size upward, becoming more erect and crowded and, like the 
Ф bracts, externally canaliculate-concave; 9 bracts bifid и-и 
their length, otherwise usually entire, bracteole similar, almost 
equally large: perianth longer than the bracts, triangular-pris- 
matic, 2-3.5 mm. x .8-1.3 mm., 3-lobed 4-34 its length, the 
lobes usually bifid and often sparingly dentate: capsule dark- 
brown, 1-1.2 mm. x .65—72 mm.; spores 16-24 и, minutely 
punctulate ; elaters contorted, somewhat attenuate at the extrem- 
ities, 160-220 и long, 0-12 и in maximum width. 
On decaying sticks, logs, and stumps, in moist woods, rarely 
on moss-covered trunks of living trees. Not uncommon in the 
Coast Range Mountains from Marin County northward. Often 
with perianths, yet rarely with capsules. Olema (27), Marin Cos

the above species.
