178 CLAVIS AGAUICINORUM. 



cartilaginous than fleshy, diftercnt in texture from the flesh of the 

 pileus (hence it is easily removed, leaving a cup or socket at its point 

 of juncture with the pileus e), furnished with an annulus, which is at 

 first continuous with the cuticle of the pileus, often moveable, some- 

 times evanescent ; volva none ; gills free, hence not sinuate or decur- 

 rent. — Hab. On the ground, mostly in rich grassy places, and more 

 often in fields than woods. 



Lepiota corresponds in structure with Chamaota, Plate CI. fig. 11, and 

 Psalliota, Plate CIII. fig. 26 ; the sections of both subgenera change 

 colour, and they have a common habitat. Goprinus is allied to this sub- 

 genus. Several species o^ Lepiota, as A. clypeolar'ms. Bull, A. cepcesiipes, 

 Sow., and A. cristatus, Fr., appear in hothouses all the year round. 

 Lepiota is readily recognized by its free gills, annulated stem without a 

 volva, and generally scaly pileus. Nearly all are autumnal and edible. 

 The species figured is Agaricus (Lepiota) procerus, Scop. Spores 

 •0006 "X -00035." 



Subgenus 3. Armtllaria, Pr. Syst. Myc. vol. i. p. 26 (Plate C. 

 fig. 3). — Veil partial, in infancy attaching the edge of pileus to the 

 upper part of stem, and often forming flocci on the pileus (g); pileus gene- 

 rally fleshy ; stem homogeneous and confluent with the hymenophorum, 

 furnished with a ring (sometimes absent in abnormal specimens), below 

 the ring the veil is concrete with the stem, often forming scales upon 

 it similar to the scurfy scales on the pileus ; gills broadly touching or 

 running down the stem. — Hab. On the ground or on stumps of trees. 



This subgenus corresponds with PJioliota, Plate CII. fig. 19, and 

 Stropharia, Plate CIII. fig. 28 ; it is also allied to Tricholoma, Glltocyhe, 

 and Collyhia, amongst the white- spored Agarics. Fries subdivides 

 Armillaria into groups, depending on their relations to one or other of 

 these subgenera. The species figured is Agaricus (Armillaria) melleus, 

 Vahl. Spores -00035" x '00023". 



Subgenus 4. Tricholoma, Fr. Syst. Myc. vol. i. p. 36 (Plate C. 

 fig. 4). — Veil absent, or if present, floccose and adhering to the mar- 

 gin of pileus ; in A. acerbus, Bull., the margin of pileus extends beyond 



Affaricus (Lepiota) granulosa, Batsch, where the gills are adnate (or even having 

 a decui'rent tooth), and the other in an Amanita which I have described under 

 the name of Agaricus adnatus, where the same condition obtains. The pre- 

 sence of the annulus, too, is not without exception ; it is often fugitive, and 

 must then be sought for in young specimens ; and it is absent from the first 

 sometimes in Agaricus (ArmillariaJ melleus, Vahl.
