132 AGARICACEiE Inocybe 



Gills usually sinuate, sometimes adnexed, adnate or decurrent, 

 adhering to the hymenophore, except 602 and 621, at first pale, 

 changing colour, but not to fuscous-ferruginous. Spores often 

 angular; pale dull tan, brownish or brown. (Fig. 34.) 



All the species, except 644, grow on the ground ; they are 

 somewhat small; none are edible, and the majority have a some- 

 what nauseous odour. 



Inocybe as defined by Fries (Hymenomycetes Europai, p. 226) has 

 no genus corresponding wholly with it in structure amongst the 

 white-, pink-, purple- or black-spored groups. Certain of the fibrous- 

 pileated species of Tricholoma, Entoloma and Stropharia might, 

 however, be separated as analogues. Inocybe was formerly included 

 in the next genus, Hebeloma. Species 598 — 646 



Mr. George Massee, in his monograph of the genus (Annals 

 of Botany, XVIII. (1904), p. 459), has rearranged the species in two 

 groups, viz. : I. Spores rough, and II. Spores smooth ; these groups he 

 has again divided into — A. Cystidia present, and B. Cystidia absent, 

 with minor distinctions as to a whitish or coloured stem and brownish 

 or olive-tinted gills. 



a. SquarroscE. Pileus squarrose, somewhat fuscous. Stem scaly, 



smooth above, same colour as pileus, solid except 204. 



598—607 



b. lacerce. Pileus torn into scales or fibres, not split into 



cracks. Stem fibrillose, paler than the pileus. 608 — 619 



c. Rimosce. Pileus longitudinally fibrous, soon cracked, partially 



adpressed-scaly. Stem fibrillose, whitish, slightly tinged 

 with the colour of the pileus. Many become yellow when 

 old. 620—634 



d. Velutince. Pileus not cracked, the cuticle fibrilloso-woven, 



becoming even or adpressedly-scaly. Stem shining, smooth, 

 whitish, mealy above. 635 — 642 



e. Viscidce. Pileus viscid, even. 643 — 646 



a. Squarrosce. 



598. I. hystrix Karst. (from the scaliness ; Ziystrix, a porcupine) 



a b c. 

 P. plane, subgibbous, mouse-colour to brown. St. attenuate 



downwards ; sc. fuscous, brownish or mouse-colour. G. adnate, 



fuscous. 

 Woods, beech. Oct. 3 x 2^ x § in. Resembling a small 578 in appearance. 



599. I. relieina Quel, (from the recurved floccose scales of the 



pileus ; reclinus, curled backwards) a c. 



P. expanded, obtuse, fuliginous or rufescent livid-brown. St. 



slightly attenuate downwards, floccoso-scaly, colour as P. G. 



adnexed, olivaceous. 



Odour almost obsolete. Woods, fir, marshy places, amongst Sphagmim. July- 

 Oct. 2£ x 3i X T 5 B in.
