or teeth, androecia rarely occurring also at a distance from the 
archegonia either on the same axis or on special branches ; 
antheridia globose, about .27 mm. in diameter, the short stalk of 
a single series of cells: 9 bracts a little larger than the subjacent 
perigonial leaves, otherwise similar; bracteole deeply bifid with 
lanceolate-subulate segments : perianth terminal on a more or less 
elongated latero-ventral branch, longer than the bracts, cylindri- 
cal or somewhat goblet-shaped, 1.3-3.2 mm. x .63-1.3 mm., 3- 
angled toward the mouth and 3-lobed 1-1 its length, the lobes 
subtruncate, rarely acute, repand-dentate: capsule brown, 
1.2 mm. x.75-1 mm.; spores 12-16 м, minutely punctulate ; 
elaters contorted, slightly attenuate at the extremities, 110-210 и 
long, 8-11 p in greatest width. 
On moldering wood (logs, stumps, etc.) in moist сайопз, oc- 
curing rarely оп moist soil in which there is considerable vege- 
table matter. “ Redwood Сайоп” (near Mill Valley) and Olema, 
Marin Co.; Turner's Сайоп (between Cazadero and Fort Ross), 
Sonoma Co.; Big River Boom (near Mendocino, 684), North 
Fork of the Little River (695), and near “ Half-Way House" 
(726), Mendocino Co.; Eureka (919, 950, 952, 1220), Hum- 
boldt Co. ; ; 
No. 695 was found in a rivulet, apparently of only periodic 
duration, in “Тһе Plains,” North Fork of the Little River, the 
substratum being sand mixed with vegetable remains. The plants, 
in this case, are wholly sterile, yet they seem to belong with 
Lophocolea heterophylla, though their habit of growth is more 
densely caespitose and the leaves are often more acutely bidentate 
than is usual. All our other Californian specimens occur upon 
dead wood.

_ Vegetative characters of the genus аз а whole agreeing very 
dosely with those of Lophocolea. Leaves more often entire. 
Archegonia terminal on a very short ventral or latero-ventral branch. 
¥ bracts I or 2 pairs, the outer pair (if present) minute, the inner al- 
Ways considerably smaller than the leaves. Perianth usually cam- 
Panulate or obconica] 3-angled only toward the 3-lobed mouth. 
Calyptra carnose, especially in the lower part, shorter than the 
Perianth or often much exserted. Sporogonium essentially as in 
Lophocolea
