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 deilexed, or both ; situated high up on 

 the stem, as in Armillaria niellea. 



Eig. 2. Ring situated about midway of the stem, deflexed and pendu- 

 lous as in Amanita muscaria. 



Fig. 3. Ring about half midway of the stem, split, and radiating out- 

 wards, 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, Lfinota 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, iu 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. 8. Gills broad. 



Fig. 2. Gills crowded. Fig. 9. Lanceolate. 



Fig. 3. Gills flexuose. Fig. 10. Ventricose. 



Fig. 4. Gills unequal. Fig. 11. Anteriorly rounded. 



Fig. 5. Bifurcated. Fig. 12. Posteriorly rounded. 



Fig. 6. Anastomosing veins. Fig. 13. Emarginate. 



Fig. 6a. Sectional view. Fig. 14. Emarginate and denticulate. 



Fig. 7. Gills narrow.
