212 CL.WIS AGARICINOUUM. 



with CUtocyhe, Plate T. fig. 5, and Clitopilns, Plate TI. fig-. 14. I 

 suspect some of the species of Flammida that approach Fholiota 

 in structure might with propriety be removed to that subgenus, and 

 Flamtmda proper be restricted to species with more or less decurrent 

 gills. Most of the species are tasteless or bitter, and none edible. They 

 appear in late autumn or early winter. Some species of Paxillus may 

 be mistaken for Flammulrs, but attention must be paid to the gills 

 separating from the hymenophorum and other characters in Paxillus. 

 The species figured is Agaricus (Flammida) sajnneus, Vr. Spores 

 •00028" X -0002". 



Subgenus 22. Crepidotus, Fr. Syst. Myc. vol. i. p. 272 (Plate 

 III. fig. 22). — Spores dark or yellowish-brown ; veil none ; pileus ex- 

 centric, dimidiate, or resupinate ; flesh soft ; stem lateral, or wanting, 

 when present, confluent with and homogeneous with the hymenophorum. 

 — Hab. Most of the species grow on wood, a few on moss. 



The species are very irregular and variable. They mostly appear 

 late in the autumn, and none are kuown to be edible. Crepidotus 

 corresponds with Pleurotus, Plate I. fig. 6, and Claudopus, Plate II. 

 fio-. 15. As at present constituted, the species of this subgenus produce 

 spores very variable in colour ; some, being truly pink, find a fitting 

 place amongst the Ilyporhodii ; other species having spores so in- 

 tensely dark, tliat I suspect they will ultimately have to be removed to 

 the FratellcE. The species figured is Agaricus (Crepidotus) mollis, 

 Schffiff. Spores -00025" X -00022". 



Subgenus 23. Naucouia. Pr. Syst. Myc. vol. i. p. 2G0 (Plate III. 

 fjo-. 23). — Spores various shades of browu, dull or bright; veil absent, 

 or attached to the edge of the pileus in young plants in the form of 

 minute flakes ; pileus convex and at first incurved, smooth, flocculent 

 or squaraulose ; stem cartilaginous, confluent with, but heterogeneous 

 from the hymenophorum. — Hab. Terrestrial or epiphytal. 



No subgenus includes so many dissimilar species as this. In size, 

 structure, the nature of the veil, and the colour of the spores, they 

 diff'er exceedingly. Naucoria corresponds with CoUybia, Plate I. fig. 

 7; Leptonia, Plate II. fig. 16; and Psilocyhe, Plate IV. fig. 30. 

 The species figured is Agaricus (Naucoria) semiorbicularis, Eull. 

 Spores -0005" X -00032". 



Subgenus 24. Galeua, Fr. Syst. Myc. vol. i. p. 264 (Plate III. 

 flo-. 24). — Spores ochraceo-fcrruginous ; veil often wanting, when pre-
