214 CLAVIS AGARICINORUM. 



Most of tlie species appear in the autumn, and several are valued for 

 their esculent properties. Psalliola corresponds with Lcpiota, Plate I. 

 fig. 2, and ChamcBota, Plate II. fig. 11. The species figured is A. 

 (PsalUota) campestris, L. Spores -00032" X -0002". 



Subgenus 27. Pilosace, Fr. (Plate IV. fig. 27).— Agrees in 

 structure with Pluteus, Plate II. fig. 12, and has the hymenophorum 

 distinct from the ringless stem ; thei'e are no British representatives. 



Subgenus 28. Stuopharia, Pr. Monog. Hymen, vol. i. p. 409 

 (Plate IV. p. 28). — Spores intense bright purple-brown, brown or slate- 

 colour; veil, if present, universal, superficial, scaly, or viscid ; stem con- 

 fluent and homogeneous with the hymenophorum; gills adnate, not 

 free and rounded behind, as in the last {PsalUota). — Hab. Terrestrial 

 or epiphytal. 



Formerly included under PsalUota, but now separated by Fries on 

 account of the different habit, different attachment of the gills, and 

 other characters. Tlie species, of which none are edible, have various 

 habits, but most are epiphytal, as are their analogues. Slroykaria cor- 

 responds with Armillaria, Plate I. fig. 3, and PhoUota, Plate III. 

 fig. 19. The species figured is Agaricus (Slropharia) cerugi7iosus, 

 Curt. Spores -00028" x -0002". 



Subgenus 29. Hypholoma, Fr. Syst. Mycol. vol. i. p. 287 (Plate 

 IV. fig. 29). — Spores brownish-purple, sometimes intense purple, almost 

 black ; veil woven into a spidery fugacious web which adheres to the 

 margin of the pileus, b. (not properly ring-shaped round the stem); 

 pileus with an inseparable pellicle; stem confluent and homogeneous 

 with the hymenophorum. — Hab. Generally stumps. 



Most of the species are gregarious and not edible. Hi/pholoma cor- 

 responds with Tricholoma, Plate I. fig. 4 ; JEntoloma, Plate II. fig. 

 13 ; Ileheloma, Plate III. fig. 20 ; and Panceolus, Plate V. fig. 33. 

 The species figured is Agaricm (HijpJiolomaJ lacrymahundus, Fr. 

 Spores -0003" X -0002". 



Subgenus 30. Psilocybe, Fr. Syst. Mycol. vol. i. p. 289 

 (Plate IV. fig. 30). — Spores purple, purple-brown, or slate-colour; 

 veil obsolete (or in a few species fugacious, when present not forming a 

 distinct ring) ; pileus glabrous, at first incurved ; stem cartilaginous, 

 ringless, confluent with but heterogeneous from the hymenophorum. 

 — Hab. All grow on the ground. 



The species are almost all gregarious, ca^spitosc, inodorous, with
