peridia covered with hispid tufts, and light-coloured peridiola = N. candida, 
and the smaller rugulose peridiola of N. emodensis. Then, too, the peri- 
diola possess the peculiar stout, spiny, coloured fibrils so cote с in the 
ал species, and the spores are roughly the same size; in shape, how- 
they are quite different. Nevertheless the peridal characters are so 
соне that I believe it should be retained under this species.

I am наме to Mr. C. С. Lloyd for the determination of this species. 
He states that it possesses the-same coloured fibrils in the tunica (the only 
character that separated N. emodensis from №. microcarpa Peck), and is 
therefore N. emodensis. These fibrils are thick, rigid, and dark-coloured, 
and possess numerous short spiny эе. Тһеу are known to оссиг 
only in this and the preceding specie 
The caespitose habit, smaller жа peridia, darker peridiola, and 
differently shaped spores separate this species from the preceding.

Peridium cyathiform, composed of a single thick felt-like membrane 
. of closely woven coloured hyphae ; mouth when young covered by a well- 
defined epiphragm, formed from the undifferentiated peridial wall. Peri- 
Tola numerous, each consisting of an outer thick loosely woven tunica, a 
thick horny dark-coloured cortex, and a loosely woven hymenial layer ; 
attached to the peridial wall by a funiculus, which is more simple in 
structure than that of a Spores hyaline, hunka, epispore thin.

The genus is анн by а single species. 16 is separated from 
Cyathus on account of the peridial wall consisting of a single layer, and 
because of the more simple funiculus, and from Nidula on account of the 
presence of funiculi.
