CLAVIS AGARICINORUM. 207 



Series 11. Htpoehodii, Fr. Epicr. p. 138. — Spores pink or salmon- colour. 



Subgenus 10. VoLV.i.RiA, Fr. Syst. Myc. vol. i. p. 277 (Plate IT. 

 fig. 10). — Spores regular iu shape, oval or pip-shaped, pink or salmon- 

 colour; veil universal, forming a perfect volva (a and c), distinct from the 

 cuticle of pileus ; stem distinct from the hymenophorum ; gills free, 

 rounded behind, at first white, then pink, soft, liquescent. — Hab. Gar- 

 dens and hot-houses, and in woods and on manured ground, growing 

 on rotten wood and damp ground ; one species is parasitic on a white- 

 spored Agaric, Jgaricus nebiilaris, Batsch. 



The different species of Volmria are veiy closely allied ; some appear 

 in spring and early summer, others later in the year ; they are almost all 

 tasteless, and none are known to be edible. Volvaria corresponds with 

 Amanita (Plate I. fig. 1). Their peculiar habitat, viz. rotten wood, 

 manured ground, etc., and their semiliquescent gills show some afii- 

 nity with Coprinns and Bolbitius, but the species of the latter genera 

 have no true volva, and differ in several other respects. 



The specimen figured is Agarkus (Foharia) vohaceus. Bull. Spores 

 •0002" X -00013". 



Subgenus 11. Cham^ota, subgen. nov. sp. Psalliotfe, Fr. (Plate II. 

 fig. 11). — Spores pale rose; stem distinct from the hymenophorum, 

 furnished with a fugitive ring ; gills free. — Hab. On the ground, or 

 on decayed wood. 



Corresponds in structure with Lepiota (Plate I. fig. 2), and PsalUola 

 (Plate IV. fig. 26). The species described under the name of " A. 

 (Pluteus?) xa)ithogrammus, Ces.," in ' Commentario della Societa Crit- 

 togamologica Italiana,' n. 2, September, 1861, appears to exactly 

 fill this place. From my examination of A. (PsalUota) cretaeeus, Fr., 

 and A. fPsalliota) ecliinatiis, Fr., I am disposed to place them also 

 here. The species figured is A. (ChamcEota) xanihogrammiis, Ces. 



Subgenus 12. Pluteus, Fr. Epicr. p. 140 (Plate II. fig. 12).— 

 Spores generally regular in sliape, but in some species approaching the 

 iiTCgdarity of Etdoloma, pink or salmon-colour, more or less bright ; 

 some approaching in colour the spores of Genus 6, Paxillus, others Sub- 

 genus 31, Flammula; veil none; pileus of the same nature with the 

 stem and gills, smooth, silky, or wrinkled ; stem ringless and without 

 a volva, distinct from the hymenophorum ; gills free, at first white, 

 then yellowish, at length pink, very crowded, almost cohering, some- 

 times subliquescent. — Hab. The species almost always grow on, or 

 close to, the trunks of trees.
