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.

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.

PLATE F.

Plate F illustrates by section or otherwise various forms of these gill-like processes characteristic of species, considered either with regard to marginal outline or position of their posterior extremity:

Fig. 1. Gills distant. Fig. 2. Gills crowded. Fig. 3. Gills flexuose. Fig. 4. Gills unequal. Fig. 5. Bifurcated. Fig. 6. Anastomosing veins. Fig. 6a. Sectional view. Fig. 7. Gills narrow. Fig. 8. Gills broad. Fig. 9. Lanceolate. Fig. 10. Ventricose. Fig. 11. Anteriorly rounded. Fig. 12. Posteriorly rounded. Fig. 13. Emarginate. Fig. 14. Emarginate and denticulate.

AGARICINI.

Subgenus Hypholoma. Hymenophore continuous with the stem, veil woven into a fugacious web, which adheres to the margin of the pileus. Gills adnate or sinuate; spores brownish purple, sometimes intense purple, almost black.--M. C. Cooke.

This subgenus has been divided into the following five groups:
