220 CLAVIS AGAKICINOKUM. 



strictly analogous, both in structure and habit, with Oirii>haUa, Plate C. 

 fig. 9; Eccilia, Plate CI. fig. 18; and Deconica, Plate CTII. fig. 32. 

 Spores -0003" X -00016''. 



Series IV. PEATELLiE, Fr. Epicr. p. 212. — Spores various shades of brownish- 

 purple, dark purine, or intense hrotvn. 



Subgenus 26. Psalliota, Fr. Epicr. p. 212 (Plate CIII. fig. 26). 

 — Spores dark brownish-purple, dark brown, reddisii-purple, or pale 

 slate; veil universal, concrete with the cuticle of the pileus, and 

 fixed to the stem, forming a ring ; pileus fleshy ; stem distinct from 

 the hymenophorum, furnished with a ring ; gills free, and rounded 

 behind, at first white, then pink, afterwards intense purple-brown. — 

 Hab. All are terrestrial, mostly growing in rich pastures and on ma- 

 nured ground. 



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

 their esculent properties. Psalliota corresponds vi'iih. Lepiota, Plate C. 

 fig. 2, and CJiamaota, Plate CI. fig. 11. The species figured is A. 

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



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

 structure with Pliiteus, Plate CI. fig. 12, and has the hymenophorum 

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



Subgenus 28. Sthopharia, Fr. Monog. Hymen, vol. i. p. 409 

 (Plate CIII. 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 {Psalliota^). — Hab. Terrestrial 

 or epiphytal. 



Formerly included under PsalUota, but now separated by Fries on 

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

 and other characters. The species, of which none are edible, have 

 somewhat various habits, but most are epiphytal, as are their analogues. 

 Stroyharia corresponds with Armillaria, Plate C. fig. 3, and Phollota, 

 Plate CII. fig. 19. The species figured is A(jaricHS (Stropharia) 

 ceniglnosus. Curt. Spores -00028" X -0002". 



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

 CIII. fig. 29). — Spores brownish-purple, sometimes intense purple, al- 

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

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