This beautiful liverwort reported, so far as the writer knows, 
by Underwood from New Jersey only (Gray’s Manual, 6th lid.), 
occurs in numberless specimens, often associated with Dicranella 
heteromalla Schimp., on a claye}' field southwest of Prookside 
Park in Brookljm Township, Cuyahoga County, Ohio. 
Although very small in size it is easily identified by its peculiar 
thallus and more or less dark purple rhizoids. The description 
of it in Gray’s Botany should, however, be corrected since the 
pedicel of the capsule when ripe surpasses the thallus consideraby 
and the elaters contain one or two ( mostly two ) spirals. 
One specimen was examined more closely as to its dimensions, 
and was found to be as follows: 
1. Length of longest rhizoid, 1.36111111. 
2. Length of “rooting” part tbroken off at end), 1.36 mm. 
3. Height of plant from uppermost rhizoid on the horizontal 
stem to the top of the split capsule, about 5.1 111111. 
4. Height of plant from uppermost rhizoid to top of thallus, 
2.64 mm. 
5. Length of pedicel (about 0.25 mm. thick) above the thallus, 
1.36 mm.; or of entire pedicel from its origin, 3.4 mm. 
6. Capsule (split and by depre.ssion expanded), height and 
width, about 1.1 to 1.2 mm. Capsules of other specimens 
(not split but ripe and globular in shape), diameter about 
0.34 to 0.90 mm. 
7. About a dozen spores were measured. Their diameter was 
between 0.044 0.048 mm.
