Rich ground and decomposing vegetable matter. Also in graperies and conservatories. Buffalo, _G.W. Clinton_; Albany, _A.F. Chatfield_. _Peck_, 35th Rep. N.Y. State Bot. =Spores= elliptical, 7–8×4µ _Massee_; 8×4µ _W.G.S._; 8–10×5–8µ _Peck_. Haddonfield, N.J., Pennsylvania, _McIlvaine_; New York, _Mrs. E. C. Anthony_; Indiana, _H.I. Miller_. July to October. Whoever has seen the seed-stalks of an onion knows the shape from which this fungus takes its name. The dense clusters are graceful, dainty, and contain many individuals of all ages—from the very young with egg-shaped heads, like pigmy C. comatus, to the fluff-capped eldest, willowy and fair to look upon. The out-door kind soon droops when matured; the young plants of a cluster will remain fresh for several days after taken from their habitat. Stems in these tufts are often quill-shaped, and the striations on the cap margins are shorter than those on their indoor cousins. These grow in hot-houses and stables. One of the two forms has a yellow cap, the other is white and fair. These forms have often come to my table as a pleasant winter surprise. Children in the hot-houses of Haddonfield, N.J., watched for its appearance among the bedded plants, sure of a present when they brought me a meal of it. Both the white and yellow varieties were equally enjoyed. The entire fungus is tender and delicious cooked in any way. =L. farino´sa= Pk.—_farina_, meal. =Pileus= thin, rather tough, flexible, at first globose or ovate, then bell-shaped or convex, covered with a soft, dense, white veil of mealy down, which soon ruptures, forming irregular, easily-detersible scales, more persistent and sometimes brownish on the disk. =Flesh= white, unchangeable. =Gills= close, free, white, minutely downy on the edge. =Stem= equal or slightly tapering upward, somewhat thickened at the base, slightly mealy, often becoming glabrous, hollow or with a cottony pith above, solid at the base, white, pallid or straw-colored, the ring lacerated, somewhat appendiculate on the margin of the pileus, evanescent. =Spores= subovate, 10–13×8µ. =Pileus= 1.5–2.5 in. broad. =Stem= 2–3 in. long, 2–4 lines thick. Mushroom beds in a conservatory, Boston, Mass. March. Communicated by _E.J. Forster_. This species is related to L. cepæstipes, from which it may be distinguished by its pileus, which is not folded on the margin, and by its larger spores. It is edible. It is very distinct from Amanita farinosa. _Peck_, 43d Rep. N.Y. State Bot. Ohio, _Lloyd_, _Prof. William Miller_ (Lloyd Myc. Notes). =L. America´na= Pk. (Plate XII, fig. 1, p. 32. Plate XV_a_.) =Pileus= at first ovate, then convex or expanded, umbonate, scaly, white, the umbo and scales reddish or reddish-brown. =Gills= close, free, white. =Stem= somewhat thickened at or a little above the base, hollow, bearing a ring, white. =Spores= subelliptical, uninucleate, 8–10×5–8µ.
