markable for its large spores, which are warty and reach the 
dimensions of Axcalypta, .055—.061 mm., and the leaves end ina 
single cuspidate cell. The plant grew with other large species of 
Orthotrichum on the bark of trees and very little of it was collected. 
Dr. Venturi has generously shared a portion of it with us; 
unfortunately this portion does not include a capsule, but from the 
description and leaves we have been able to determine that it is 
very nearly allied to U. subulata and U. subulifolia CM. & Kindb. 
We have not seen specimens of U. sudulata, but we should not be 
surprised to find that these three species were one. Unfortunately 
Kindberg has no idea of the use of measures in descriptions, and 
never seems to look at the spores, but his description of U. sudbu- 
lata, as far as it goes, agrees with U. megalospora, which has pre- 
cedence by two years.

The description of this species is most unsatisfactory, being 
only a comparative one, as follows: - 
“Differs from U. subulata in the stem being more branched, the 
leaves when dry twisted or subcrisped, sparingly papillose, revo- 
lute at the basal margin at least on one side; the basal cells elon- 
gate, alar indistinct ; capsule very small, short-obovate, costate, 
finally subcylindric; pedicel not very long; calyptra nearly naked.

We have received from Prof. Macoun fine specimens from this 
locality, numbered 127, which we have examined and measured. 
The following are our observations: | 
Plants small, light yellow; stems slender, creeping and tomen- 
tose at base, branches erect, 5—7 mm. high; leaves crisped when 
'Y, Spreading when moist, from an erect, ventricose base, 1-2 
mm. long, narrowly acuminate, carinate with more or less recurved 
margins, vein thick ending below the cuspidate apex; cells bluntly 
Papillose, upper rounded, .005-.008 mm.; lower longer, narrower, 
‘©13-.027 mm., often brown or yellow. : 4 
Autoicous, the antheridia in large, brown buds, with broa 
bracts. Seta long, slender, including the vaginule to tip of lid, 
5-7 mm. Capsule small, 1 mm., when ripe ovoid, becoming elon. — : 
gated when Pte with a long tapering neck, which i 
when dry; lid apiculate, beak long, .216 mm., bordered with yel-
