Fungi in agriculture. 456 FUNGOUS DISEASES OF PLANTS the disappearance of starch, proteids, and cellulose suggests that the fungus produces amylolytic, proteolytic, and cyteolytic ; A direct study of this point was attempted by making extractions from fresh, young fruit bodies, and testing these. While this may not be an absolute criterion for the basis of an opinion as to the enzymes produced in the my- celium, it is nevertheless inter- esting that laccase, tyrosinase, amylase, emulsin, protease, lipase, rennetase, and coagu- lase were seemingly present, "whereas negative results were obtained in the tests for pec- tase, maltase, invertase, treha- lase, and cytase. However, a study of the destruction of wood by the fungus furnishes evidence that the. mycelium produces cy- tase and possibly ; The sporophores arise singly or in clusters of a few brackets, usually during summer and early autumn. It requires but a brief period for these sporophores to attain their growth, brackets measuring 15—25 cm. in width having been observed to com- plete growth within two weeks. The mature sporophore is yel- lowish brown above, and the surface of the cap is thrown into characteristic brown scales. The plants are commonly 15-30 cm. broad, although one speci- men measuring 65 cm. and weighing approximately six and a half pounds has been found (Buller). The margins of the pileus are slightly revolute even on maturity, the lower surface of the pileus yellowish, with pores at first small, later expanding, and Fig. 225.
