NYCTALIS. 137 



Easily distinguished from C. lobatus by the thinner, reticulated gills ; Canthar- 

 without the rudiment of astern, adfixed to mosses by fibrils at the vertex, ellus. 

 It approaches the Cyphellce in many respects. 



On mosses. Uncommon. May. 



Name rete, a net ; ruga, a wrinkle. From the reticulated gills. Fr.

16. C. lobatus Fr. Pileus scarcely 2.5 cent, (i in.), dark 

 fuscous when in full vigour, becoming pale when dry, sessile, 

 horizontal, membranaceous, somewhat round, at first adfixed, 

 entire, then somewhat lateral and lobed. Gills fold-like, some- 

 what distant, distinct, branched, of the same colour as the pileus. 



On mosses in bogs. Uncommon. Autumn. 



When old often very much lobed and crisped, and then the wrinkles, 

 especially at the base, are reticulated, though towards the margin they con- 

 tinue distinct. M.J.B. Spores ovoid-pruniform, 10 mk. Q. Name lobatus,

GENUS XII. Arrhenia Fr. Summ. Veg. Scand. p. 312. Arrhenia. 



Membranaceous, very tender, hymenium inferior and striate 

 with few, delicate, slightly raised, simple, straight veins, which 

 take the place of gills. Spores pallid. Minute, moderately per- 

 sistent, 'variable in form. S trice not decurrent. Compare Can- 

 thar ellus Brownii. Fr. Hym. Eur. p. 461. 



No British species. 



GENUS XIII. Nyctalis (v6, night. From inhabiting dark Nyctalis. 

 places.) Fr. Syst. Orb. Veg. p. 203. 



Hymenophore continuous with the stem. Gills fleshy, thick, 

 juicy, obtuse at the edge, not decurrent on the stem nor fold-like. 

 Veil (in species which have been fully observed) floccoso-pruinose. 

 Fleshy fungi, not reviving, of uncertain and irregular occurrence, 

 differing in many respects from one another and from the rest of 

 the Agaricini. Fr. Hym. Eur. p. 462.
