Appendicula´ti. Pileus hygrophanous, smooth.
H. incer´tum Pk. (Plate [XCVII]a.) Pileus fragile, convex or subcampanulate, then expanded, hygrophanous, often radiately wrinkled, whitish with the disk yellowish, the thin margin sometimes purplish-tinted, often wavy, adorned by fragments of the white flocculent fugacious veil. Lamellæ close, narrow, whitish then rosy-brown, the edge often uneven. Stem equal, straight, hollow, easily splitting, whitish with a frosty bloom or slightly scurfy at the top. Spores elliptical, purplish-brown, 8×5µ.
Plant gregarious or subcespitose, 2–3 in. high. Pileus 1–2 in. broad. Stem 1–2 lines thick.
Ground among bushes. Green Island and Sandlake. June and July.
The veil is sometimes so strongly developed as to form an imperfect ring. The color is nearly white from the first. Peck, 29th Rep. N.Y. State Bot.
As the name indicates, I was uncertain whether this was a form of H. Candolleanum, to which it is very closely related, but as Fries says of that “Gills at first violaceous,” and as our plant has them at first white or whitish, I concluded to risk the uncertainty on a new species.
I have seen Central Park, New York, well covered with it in May. It is also common in the vicinity of Boston. Of very agreeable flavor and delicate substance. The profusion of its growth compensates for its small size. Macadam.

Tender. One of the best.
