TABLE OF THE SUBGENERA OF HYPORHODII. 

 A. Stipe central, lamellce free. 



10. VoLVARiA. — Veil universal, discrete, membranaceous, persistent. 



11. Pluteus. — Veil none, margin of the pileus straight. 



B. Stipe central, lamellce attached, 

 a. Stipe fleshy or fibrous. 



12. Entoloma. — Lamellse sinuate. 



13. CuTOPiLDS. — Lamellse decurrent. 



h. Stipe cartilaginous. 



14. Leptonia. — Pileus convexo-plane, the margin at first inflexed. 



15. NoLANEA. — Pileus campanulate, the margin straight. {No 

 species yet.) 



Subgenus X. — Volvaria, Fr. 



Spores roSe-color. Veil universal, free persistent, discrete from the 

 epidermis of the pileus (volva). Lamellse rotund ate -free, ventricose 



81. A. BOMBYCiNUs, SchssfF. — White. Pileus fleshy, soft, campanu- 

 late then expanded, somewhat umbonate, silky-fibrillose. Stipe solid, 

 tapering upward, glabrous; the volva very ample. Lamelke free, Uesh- 

 color. Spores regular, .007X.005 mm. 



Upon trunks of trees in woods; sometimes growing out of knot-holes 

 of standi7i(j trees, or even out of the augur holes in Sugar Maple. 

 Pileus 3-5 in. broad, the stipe about 3 in. long. The pileus is at first 

 inclosed in the large slimy tough volva, but is soon protruded leaving 

 the volva persistent at the base of the stipe; it usually remains broadly 

 campanulate, and is covered over with white or yellowish-while silky 

 fibrils. This is one of the most showy Agarics, and is not uncommon 

 in the Miami Valley. 



Subgenus XI. — Plcteus, Fr. 



Spores rosy. Destitute of volva and annulus. Laraellai rotundate 

 behind, free.
