Mycologia 
According to Clinton^ the sorl of this fungus surround pedun- 
cles, pedicels, bases of rachises, and sometimes stems. On Cy- 
perus, however, the sori are mostly found surrounding portions 
of the stems and sometimes running up on the leaf sheaths. They 
measure i to 4 cm. in length and when young are covered with a 
white fungal membrane which flakes away at maturity and reveals 
a dark agglutinated spore mass. The spores are dark-brown and 
verruculose, and have the form of spheres which have been com- 
pressed or concaved on one side ; they thus appear to be spherical, 
subspherical, reniform, or irregular, depending on the side from 
which they are seen. Their larger diameter measures 16 to 20 
microns and the compressed diameter 8 to 12 microns. These 
characters agree with those given by Clinton for Cintractia 
leucoderma.
