(Berkeley and Curtis, in Berkeley, Introduction to Cryptogamic Botany, London, 1857, 313 (illustration but no description); Berkelej^ (description). Notes on North American Fungi, Grevillea, 3, 1874, 64.) cro.ca'tus. L. adj. crocatus saffron-yellow. Vegetative cells: Cylindrical rods with blunt, rounded ends, 1.3 to 1.7 by 3.0 to 11.0 microns. Fruiting body: The cysts are at first spin- dle-shaped, widening at the base to become almost conical in the mature state. Ini- tially straw-colored, they finally turn golden yellow. When mature, they are attached to the stalk by the remains of pedicels. Cysts are borne in spherical groups at the tips of stalks which are almost always branched. The stalks are 600 microns or more in height, covered with longitudinal striations and sometimes spirally twisted. Originally orange in color, they eventuallj^ turn brown. Mature cysts are 9 to 16 by 15 to 37 microns; the resting cells within them are 1.0 to 1.2 by 2.4 to 3.8 microns. Source: Isolated from a decayed gourd from South Carolina. Also found by Thaxter (Bot. Gaz., 17, 1892) on melon rind from south Carolina and on old straw from Cey- lon and Cambridge, Mass. Quehl (Cent. f. Bakt., II Abt., 16, 1906) foimd it on dung from Java and on deer dung from Berlin. Habitat: Found on decaying organic matter in soil and in the dung of various animals.

Fruiting bodies: Cysts ellipsoidal or spherical, 16 to 40 by 30 to 60 microns. Origi- nally flesh-colored, they become a vivid orange -red during maturation; may turn chestnut-brown when kept for long periods in moist air. The stalk, 135 to 400 microns high, is usually nearly colorless, sometimes a light yellow-brown, and in most cases is unbranched. Resting cells in cysts are 0.8 to 1.0 by 2.5 to 3.5 microns.
