222 CLAVis AGAraciNonuM. 



analogous with OmpJialia (Plate C. fig. 9), EcclUa (Plate CI. fig. 18), 

 and Tuharia (Plate CII. fig. 25). Spores -00034" x -0002". 



Series V. Coprinaeii, Fr. Epicr. p. 234. — Sjwres Hack. 



Subgenus 33. Pan.^olus, Fr. Epicr. 234 (Plate CIV. fig. 33).— 

 Veil, when present, interwoven, sometimes wanting ; spores black, 

 oval, plain, lem^on-shaped, or echinulate ; pileus somewhat fleshy, viscid 

 when moist, shining when dry, not becoming purple or brown, 7iever 

 striate, the margin exceeding the variegated gills. — Hab. Almost all 

 grow on dung, often near towns, in summer and autumn. 



This and the following subgenus diifer from all the preceding in 

 their black spores, and occupy an intermediate position between Jga- 

 ricus and Coprinus, agreeing with the latter in the colour of the 

 spores, but joined more properly to the genuine Agarics by the gills not 

 deliquescing. Although the veil may be entirely absent in some species, 

 yet they are so allied that they cannot be well sepai'ated. It is, how- 

 ever, difficult to place this subgenus in proper connection with the 

 foregoing, but I consider its nearest ally to be Hijplioloma, Plate CIII. 

 fig. 29, and the subgenera in corresponding places on the preceding 

 plates, principally on account of the nature of the veil ; and the 

 margin of pileus exceeding the gills as in Agaricus (Tricholoma) 

 acerhus, Bull ; some of the species are, however, allied to Psalliota, 

 Plate CIII. fig. 26, and its congeners on the previous plates, with which it 

 agrees well in several characters, such as the habitat, manured ground, 

 etc. ; this subgenus (like several others) would probably bear subdivision, 

 which is not at present advisable. A. phaleenarum, Fr., is said to be 

 edible. The species figured is Agaricus (Fanceolus) separatus, L. 

 Spores -0006" x -0004". 



Subgenus 34. Psatkyrella, Fr. Epicr. 287 (Plate CIV. fig. 34). 

 —Spores black, oval, plain or echinulate ; veil inconspicuous, not in- 

 terwoven, generally absent ; pileus membranaceous, striate, margin 

 straight, adpressed to the stem, not exceeding the gills ; stem confluent 

 with but heterogeneous from the hymenophorum ; gills adnate or free. 



-The species are all very slender, and the only other subgenus with 

 black spores {Panceolus, fig. 33) is readily distinguished by the charac- 

 ters of the pileus ; it agrees in every point with Psathgra, Plate CIII. 

 fig. 31, except the colour of the gills being never brown or purple, 

 and the spores black. It also agrees, more or less, in structure with
