. Bulletin : report of Agricultural Experiment Station, Agricultural and Mechanical College, Auburn, Ala. Agriculture -- Alabama. 340 pileus (pi) resting on a central stalk ; underneath the cap appears a series of thin radiating plates whicli are known as the lameUce or gills; part way down the stem appears a shreddy membranous ring called the annulus ; this ring {an) is orignally in the form of a veil which extends from the stem to the margin of the pileus so as to completely cover up the gills; as the pileus grows larger the veil breaks away trom the edge of the pileus and remains in the form of a more or less complete ring about the stem. These parts are shown in Figure 1 which illustrates this Fig. 1 Agaricus campestris; Edible; showing mycelium {my) constituting the underground growing portion of the plant; the annulus (an); and the pileus or cap (pi) being turned toward us does not show the gills or lamellae beneath. The line a a repre- sents the surface of the ground. Color of pileus white or grayish. About % natural size of ordinary specimens, though the size varies grea ly ; the stem also is often very short. The common field agaric has a normally white pileus though this may be more or less varied with grayish flecks or spots. It can be readily distinguished by the four fol- lowing marks, all of which should be present to be certain of the species, though the first two will separate it from. all the deleterious forms that might be confused with it:.
