218 CI.AVIS AGAIIICINOKUM. 



(lleheloma) fa-slidilis, Fr. A very common species, closely allied to J. 

 crustulinoformis, Bull. Spores -0004" x -0003". 



Subp;enus 21, Plammula, Fr. Syst. Mye. vol. i. p. 250 (Plate ClI. 

 fig. 21). — Spores in most species purely ferrugineous, occasionally 

 approaching yellow ochre, always bright in colour ; veil filamentous, 

 often obsolete ; pileus fleshy, and, as the subgenus is at present con- 

 stituted, very variable. It may be, — 1, covered with an inseparable 

 and fibrillose cuticle; 2, covered with a more or less viscid and se- 

 parable cuticle; 3, moist, and with no separable cuticle; 4, neither 

 pelliculose nor viscid, and broken up more or less into scales or fibrils ; 

 stem fleshy, fibrous, confluent, and homogeneous with the hymeno- 

 phorum ; gills adnate, acutely adnate, or decurrent. — Hab. On the 

 ground or on wood. 



Fries says the natural affinity of Flammula is with PhoUota, 

 Plate CII. fig. 19, but I consider all true IlammidcB should correspond 

 with Clitocybe, Plate C. fig. 5, and Clitopilus, Plate CI. fig. 14. I 

 suspect some of the species of Flammula that approach PhoUota 

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

 Flammula 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 Flammula, but attention must be paid to the gills 

 separating from the hymenophorum and other characters in Paxillus. 

 The species figured is Agariciis (Flammula) sajniieus, Fr. Spores 

 •00028" X -0002". 



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

 CII. fig. 22). — Spores dark or yellowish-brown ; veilnoue; 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 known to be edible. Crepidotus 

 corresponds Avith Pleurotus, Plate C. fig. 6, and 'Claudopus, Plate CI. 

 fig. 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 Hyporliodii ; other species having spores so in- 

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

 the Pratellce. The species figured is Jgaricus (Cripidotus) mollis, 

 SchiciV. Spores -00025" X -00022".
