46 Thirty-third Annual Report of the 



and lower part of the stem. In the European plant these scales are 

 said to be imbricating. I have not found this form in our State, but it 

 occurs farther south. In the other, the bulb and lower part of the 

 stem are covered with white mealy or granular particles. This form 

 occurs on Long Island. The annulus also and the upper part of the 

 stem, when young, are covered with floccose or mealy particles. The 

 former is soon lacerated and a part of it frequently adheres to the mar- 

 gin of the pileus and the edge of the lamellae. Sometimes there is 

 very little of it left to form a ring on the stem. This lacerated an- 

 nulus and the peculiar deeply-rooting bulb are marked and distin- 

 guishing features in this species, A. echinocephalus, Vitt., is appar- 

 ently a closely-related species, but is characterized as having a shining 

 pileus with pyramidal acute seceding warts and a distant persistent 

 annulus. The lamellae are also said to become green. A. albellus, 

 Scop,, and Aminata pellita, Seer., are regarded by Fries as synonyms. 



Authors are divided in their estimate of the qualities of this fungus, 

 one saying that it is very poisonous, another, that it is scarcely edible, 

 and another, that its flesh is white and of an excellent flavor. In any 

 case it is too scarce with us to be of much value, 



Agaricus strobiliformis, Vitt. Fir-cone Agaric. Pileus convex or 

 nearly plane, rough with angular super sistent toarts,wh\te or cinereous, 

 sometimes yellow on the disk, the margin even and extending a little 

 beyond the lamellae ; lamellae free, rounded behind, not reaching the 

 stem, equal or slightly tapsring upward, solid, floccose-scaly, white, 

 bulbous, the bulb very large, margined above and furnished with one or 

 two concentric furrows, somewhat pointed below, floccose mealy when 

 young; spores elliptical, .0005 in. to .0006 in. long, ,0003 in, to 

 .0004 in. broad. 



Plant 6 in. to 10 in. high, pileus 6 in. to 10 in. broad, stem 8 lines 

 to 15 lines thick. Autumn. 



This Agaric, which usually attains a very large size, is quite 

 rare with us. It is generally of a white or whitish color, 

 but sometimes yellowish on the disk, and it has the pileus rather 

 thickly studded with firm angular mostly persistent warts which 

 are often flattened at the top in such a way as to resemble some- 

 what the scales of a pine cone, whence the specific name. They 

 are generally whitish though sometimes tinged with brown. In 

 some instances they fall away and leave the pileus nearly smooth. 

 The annulus is large, and as in the preceding species is often torn or 

 lacerated. The bulb at the base of the stem is one of the peculiar 

 and distinguishing features of the species. It is very large, some- 

 times attaining a diameter of two and a half inches, and at the upper 

 part a slight furrow intervenes between its narrow margin and the 

 stem, as if produced by the impressed margin of the young pileus. 

 Sometimes a second furrow surrounds the bulb a little below this, and 

 below the second furrow the thick exterior coat of the bulb is split 

 longitudinally in several places, thus giving it a lobed appearance. 

 The larger part of the bulb often appears above the surface of the 

 ground, but it is somewhat pointed or conical below and thus slightly 

 penetrates the earth, but it has not the long distinct tap root that so 

 strongly characterizes the preceding species. All traces of the volva 

 soon disappear from the bulb. The plant formerly referred to A. 

 muscarius as variety major is to be referred to this species. The solid
