A. pantheri´na De C.—spotted like a panther. Doubtful. Pileus commonly olivaceous-umber when young, fleshy, convex then flattened or somewhat depressed, with a sticky pellicle, which is at first thick and olivaceous dingy-brown, then thinned out, almost disappearing and livid, the disk only becoming brownish; margin evidently striate; the fragments of the volva divided into small, equal, white, regularly arranged, moderately persistent warts. Flesh wholly white, never yellow beneath the pellicle. Stem 3–4 in. long, ½ in. thick, at first stuffed then hollow with spider-web fibrils within, equal or attenuated upward, slightly firm and sometimes scaly downward, greaved at the base by the separable volva which has an entire and obtuse margin. Ring more or less distant, adhering obliquely, white, rarely superior. Gills free, reaching the stem, broader in front, 3–4 lines broad, shining white.
It is readily distinguished from A. muscaria, var. umbrina, by the white flesh never becoming yellow beneath the pellicle. Variable in size and color, which, however, is never red or yellow, and in the position of the ring.
In woods and pastures. Stevenson.
