214 CLAVIS AG4HICIN0UUM. 



fill this place. From my examination of A. (Psalliota) cretacem, Fr., 

 and A. (PsalUota) ecldnalas, Fr., 1 am disposed to place tliem also 

 here. The species figured is A. (Chamaota) .ranthogramvius, Ces. 



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

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

 irregularity of Entoloma, pink or salmon-colour, more or less bright ; 

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

 subgenus 3 1, Flammida ; veil none ; piieus 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. 



The characters of this subgenus agree with those of Volvaria, Avith 

 the exception of the volva, wliich is absent in Pluteus. Fries appears 

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

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

 crete veil, which would give an analogy with Lepioia, Plate C. fig. 2. 

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

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

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

 subgenus Pilosace 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, Schseff. Spores 

 •00023" X -00018". 



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

 Spores extremely irregular in shape, salmon colour, pink, or more or less 

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

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

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

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

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

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

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

 are terrestrial. 



* Since this was in print a probable representative has been found amongst 

 the Leuvospori (see page 141).
