The genus Cookeina was established by O. Kuntze to take the 
place of Trichoscypha of Saccardo, the latter name being unten- 
able. A month later the genus Pilocratera was proposed by 
P. Hennings for the same reason, apparently without knowledge 
of Kuntze’s work. The name Pilocratera was adopted by Lindau 
in Engler & Prantl’s Natiirlichen Pflanzenfamilien, but incorrectly 
so since the name proposed by Kuntze had priority. The genus 
is most closely allied to Sarcoscypha of Saccardo, but the species 
which are essentially tropical are probably distinct enough to be 
retained in a separate genus. 
As the name implies, the plants are usually hairy and the hairs 
w'hen present are composed of a fascicle of mycelial threads the 
whole tapering into a bristle-like apex. In one species, C. Colen- 
soi, which is here included with the genus, the hairs are absent 
and the outside of the cup is clothed with granules consisting of 
loosely arranged cells. While well-developed hairs are wanting 
in this species other characters indicate a close relationship with 
the other members of the genus to which it undoubtedly belongs. 
Another character of the genus which deserves especial men- 
tion is the peculiar markings of the spores. Three of the four 
species examined have striate spores. In one species, C. insititia, 
no striations were observed. However, as only one collection of 
this species has been seen it is possible that a further study of 
the species will reveal this character. The striations are not in
