(Continued from page 182.) 



Series II. Htpokhodii, Fr. EiDicr. p. 138. — Spores pinh or approaching 

 salmon-colour or lilac. 



Subgenus 10. Volvaria, Fr. Syst. Myc. vol. i. p. 277 (Plate CI. 

 fig. 10). — Spores regular iu shape, oval or pip-sliaped, 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, 

 ifounded 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 nebularis, Batsch. 



The different species of Volmria are very 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 0. fig. 1). Their peculiar habitat, viz. rotten wood, 

 manured ground, etc., and their liquescent gills show some affinity 

 with Coprinus and Bolbitius, but the species of the latter genera have 

 no true volva, and differ in several other respects. 



The specimen figured is Jgaricus (Folvaria) volvaceiis, Bull. Spores 

 •0002" X -00013". 



Subgenus 11. CHAMiEOTA, subgen. nov. sp. PsalUotcs, Fr. (Plate CI. 

 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 C. fig. 2), and Faalliofa 

 (Plate cm. fig. 26). The species described under the name of ^' A. 

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

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