210 CLAVIS AGARICINOKUM. 



Leptonia and Eccilia), subcampamilate, and papillose, not umbilicate, 

 at first straight and pressed to the stem, not incurved as in Leptonia ; 

 stem cartilaginous, fistulose, sometimes stuffed,confluent with, butlictero 

 geneous from the hymenophorum ; gills not decurrent. — Hab. Generally 

 terrestrial, growing on grassy hills, and in wet places iuwoods. 



The species are thin, slender, inodorous, and brittle (but some very 

 tenacious), growing in summer and autumn. Nolauea corresponds 

 with Mycena, Plate I. fig. 8 ; Galera, Plate III. fig. 24 ; Psathyra, 

 Plate IV. fig. 31; and Psathyrella, Plate V. fig. 34. Fries, in 

 his ' Mouographia,' has not reversed the sequence of Nolanea and 

 Eccilia to make them accord with Omphalia and Mycena amongst the 

 Leucospori. Leptonia, Nolanea, and Eccilia are very nearly allied by 

 many characters. The species figured is Agaricm (Nolanea) pascmis, 

 P. Average size of spores •0003". 



Subgenus 18. Eccilia, Fr. Syst. Myc. vol. i. p. 207 (Plate II. fig. 

 18). — Spores salmon-colour; pileus generally umbilicate, disk homo- 

 geneous, margin at first incurved, as in Leptonia; stem hollow, confluent 

 with, but heterogeneous from the hymenophorum ; gills truly decurrent. 



Corresponds with Omphalia, Plate I. fig. 9 ; Tubaria, Plate III. 

 fig. 25, and Beconica, Plate IV. fig. 32. The species figured is 

 Agaricus (Eccilia) Parkensis, Fr., for specimens of which I am in- 

 debted to Mr. C. E. Broome. Average size of spores •00027". 



Series III. Dermtni, Fr. Epicr. p. 160. — Spores various shades of reddish- 

 broivn, broion, red, or yellotvish-hroivn. 



Subgenus 19. Pholiota, Fr. Syst. Myc. vol. i. p. 240 (Plate III. 

 fig. 19). — Spores sepia-brown, bright yellowish-brown, or light red; 

 stem confluent and homogeneous with the hymenophorum, furnished 

 with a ring, persistent, friable, or fugacious. — Hab. All the British 

 species grow on stumps except five, which grow on the ground prin- 

 cipally in damp, mossy places. 



A few species are said to be edible, but they cannot be recom- 

 mended. Pholiota is analogous to Armillaria, Plate I. fig. 8, and 

 Stropharia, Plate IV. fig. 28. There is some danger of confusing 

 Pholiolce with Cortlnarii, but attention must be paid to the spidery 

 veil and the rust-of-iron tint of the spores in the latter, and the 

 habitat of the former. The species figured is Agaricus (Pholiota) 

 squarrosus, Miill. Spores ^00022" X -0001 7".
