H ab. On the culms of living Grasses; Summer, very frequent.
Plant half an inch to two inches in length, surrounding the culms of living
grasses, of a bright orange-yellow colour. In its young state it is white,
and of a soft fleshy consistence. In a few days, it acquires a yellow co-
our, and Æe receptacle becomes dotted on the surface, which, however
still reniams smooth and even. In maturity, and as it grows old, the
receptacle shrinks, while, in the place of the dots above mentioned, the
oiifices of the enlarged perithecia become prominent, and render the
surface granulated. Perithecia horizontal, ovate, contiguous, yellow,
o a carnose substance, their summits much rounded; filled with a gelatinous
mass, containing frie fructification. Thecoe numerous, s L -
del, very attenuated and acute at each extremity, nearly as long as the
perithecia themselves, containing 3-5 oblong yellow sporidia. When
mature, the thecæ escape spontaneously from the perithecia.
