PLATE E.

Plate E ill.u.s.trates 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_.

Fig. 6. Ring narrow, scarcely perceptible above the middle of the stem; remnants of the veil adhering to the margin of the cap as a fugacious web.

Fig. 7. Ring generally wanting--_Tricholoma nudum_. Remnants of the veil seen on the margin of the cap.

Fig. 8. Remnants of the veil appearing on the margin of the cap as a fringe, and particularly on the stem as a mere fibrillose zone of a darker color as in the _Cortinarii_.

Fig. 9. Plant exhibiting the cortina unbroken, the extremities of its delicate arachnoid threads attached to cap and stem, respectively.

Fig. 10. Section of a Russula, in which genus the ring is always wanting; veil none.
