Ascomata scattered or gregarious, each with a short but dis-

the margin upturned, when dry cupulate with the margin inrolled, 
0.3-0.5 mm. in diameter, entirely white, but old specimens often 
becoming brownish, clothed externally with a thick coating of 
white hairs; hairs short, not more than 50 # long, 3-4 4 thick, 
hyaline, rarely septate, more or less irregularly curved or flexuous, 
the tips uncinate, obtuse, smooth or granular; asci clavate, nal 
rowed at the tips which are not blue with iodine, 35-45 x 5-6 i 
spores 8, biseriate, hyaline, continuous, smooth, clavate-cylindri- 
cal, 8-10 x 2 4; paraphyses abundant, scarcely exceeding the ascl, 
lanceolate-acute at the tips, 3 2 wide at the broadest part, hyaline, 
septa not seen. : 
On decaying stems and rootstocks of Eguisetum hyemale, lying 
on the ground in wet places, Ithaca, N. Y., April, May and Nov.

This is distinguished among the white species of the genus 2 
the character of the external hairs. These are sometimes 5° ar

lected in the spring they are quite prominent. Their Rte 
flexuous character and curved tips are peculiar. Not beto 
reported from America.
