172 CHARACTERS OF SOME GNAPHALIOID COMPOSITÆ. 
There are two or three varieties; one approaching very near to 
L. gyriforme, and another very obtuse, and closely resembling 
L. calatum. 
* L. pyriforme, Schæff. Hook. fil., No. 126, cum ic. 
Has. On dead wood. Sikkim, 8,000 feet. October. 
The specimens vary in length of the stem, bnt none are so strongly 
stipitate as the common form. 
350. L. microspermum, n. s.; peridio toto flaccido persistente, ore 
rotundo dehiscente, cortice squamulis acutis demum exasperato ; strato 
sterili parvo, capillitio uniformi; sporis globosis minimis. Hook. fil., 
No. 13. 
Has. On the ground. Darjeeling. June. 
From 1—1 inch across, subglobose, obtuse, sending out one or more 
strong roots, from which proceed some white fibres ; at first reddish- 
brown, obscurely rimose, rough with minute brown raised scales, at 
length paler, smooth below, opening by a small round aperture. Barren 
stratum small, scarcely distinguishable, except on accurate inspection, 
from the capillitium, which is uniform, without any columella. Spores 
very minute, globose, olive-green, quite smooth, rarely pedicellate. 
This little species has all the characters of L. pusillum, but the 
diameter of the spores is not above half as large.
