208 CLAVIS AGAlllCINOUUM. 



The characters of this subgenus agree with tliosc of Folvaria, with 

 the exception of the volva, which is absent in Pluteiis. Fries appears 

 to think it is doubtful whether the pellicle of the pileus, always fibrous, 

 flocculose, or pruinose, should not be considered as an universal con- 

 crete veil, which would give an analogy with Lqnoia, Plate I. fig. 3. 

 He has recently established a new subgenus of purple-spored Agarics 

 (see Plate IV.) under the name of Pilosace, with (excepting the 

 spores) precisely the characters of Pluteus. Plicteiis and this new 

 subgenus Pilomce are undoubtedly allied, but, strangely enough, they 

 have no known representatives amongst either the white- or brown- 

 spored groups. The species of Pluteus appear in spring, early sum- 

 mer, or late in the autumn. They are tasteless, and none edible. 

 The species figured is Agaricus (Pluteus) cervbms, Schfeff. Spores 

 •00023" X -00018". 



Subgenus 13. Entoloma, Fr. Epicr. p. 143 (Plate II. fig. 13).— 

 Spores extremely ii-regular in shape, salmon colour, pink, or more or less 

 approaching bright red.or brown ; veil, as in Tricholoma and Hebeloma, 

 " potential rather than definite ;" pileus, with a margin at first incurved, 

 never at first umbilicate, fleshy or thin according to the species, viscid, 

 smooth, bygrophanous, dry, silky, or flocculose ; stem fleshy-fibrous, 

 sometimes almost waxy, continuous with the hymenophorum, and homo- 

 geneous with it; gills sinuated, as in Tricholoma, etc., almost free, or 

 more or less adnate, sometimes parting from the stem. — Hab. All 

 are terrestrial. 



Allied to Tricholoma, Plate I. fig, 4, but, with few exceptions, the 

 species of Entoloma are much thinner and often brittle. Many possess 

 the odoin- of new flour, but none are edible, and some highly poisonous. 

 They appear in summer after heavy rains. Besides corresponding 

 with Tricholoma, Entoloma agrees in structure with Hebeloma, Plate 

 III. fig. 20, and Ilypholoma, Plate IV. fig. 29. The species figured 

 is Agaricus (Erdoloma) sinuatus, Fr. {A. fertilis of Berkeley's ' Out- 

 lines '). Average size of spores -00035" X -00025". 



Subgenus 14. Clitopilus, Fr. Epicr. p. 148 (Plate II. fig. 14).— 

 Spores salmon colour, in some species very pale, almost white, pip- 

 shaped, somewhat irregular spheres or altogether irregular as in Ento- 

 loma, fig. 13 ; pileus viscid, smooth or pruinose, dull white, cinereous or 

 brownish, generally fleshy ; stem fleshy or fibrous, confluent with the 

 hymenophorum and homogeneous with it ; gills dccurrent, never 

 sinuated. — Hab. All arc terrestrial.
