Published in Serial Form--=No. 3=--Price, 50c. per number. WASHINGTON, D. C.: A. R. Taylor, Publisher, 238 Mass. Ave. N.E. 1897. [Illustration: Plate E. THE NORRIS PETERS CO., PHOTO-LITHO., WASHINGTON, D. C.] PLATE E. Plate E illustrates various forms and positions of the annulus or ring characteristic of certain species of mushrooms, together with the cortina or veil of which the ring, if present, is the remnant, in some species, either as it appears entire or as a fringe on the margin of the cap, contrasting these forms with a sectional view of a species in which the veil or ring is always wanting. Fig. 1. Ring broad, reflexed or deflexed, or both; situated high up on the stem, as in _Armillaria mellea_. Fig. 2. Ring situated about midway of the stem, deflexed and pendulous as in _Amanita muscaria_. Fig. 3. Ring about half midway of the stem, split, and radiating outwards, as in _Agaricus arvensis_. Fig. 4. Ring drooping. Fig. 5. Ring persistent, movable, wholly detached, in age, from the tall and slender stem, upon which it easily slips up and down. A species of great beauty, _Lepiota procera_.
