MYCENA. • 105 



Hdbk., p 351 ; Cke., lUustr., pi. 112Sb (as Marasmius- 

 cohacrens). 



On trunks or on tlie ground among leaves. 



Amongst pine leaves in great perfection. It has much 

 affinity with A. halaiimius, B. ; but that has the margin of 

 the gills purple. They have, however, the same fulvous 

 bristles on the surface. (B. & Br.) 



In woods among leaves, also on wood. I have found it 

 growing in tufts on fir trunks. ^Vith the habit of Maras- 

 miu.% but allied to M. galericulata in the gills. 



Mycena excisa. Lasch. 



Pileus convex, somewhat umbonate, rugulose, brownish ; 

 gills somewhat cut out behind and almost free, ventricose,. 

 thick, hoary ; stem even almost glabrous, base rooting. 



Agaricus excisus, Lasch; Linnea, vol. iv. (1829), p. 534,. 

 (No. 538.) 



Most nearly allied to Agaricus polygrammiis. Pileus; 

 campanulate then convex, very obtuse or umbonate, about 

 1 in. across ; disc slightly fleshy, pallid-fuscous or grejdsh- 

 fuscous. Gills in series of four, somewhat distant, connected 

 by veins, paler in colour than the j)ileus, very broad and 

 ventricose in front, very much narrow^ed behind, scarcely 

 adnexed. Stem 1-^ in. long, 1^-2 lines thick, grey. Tough;, 

 almost tai^teless. 



Gregaiious. On trunks, especially pine. Sept., Nov. 



The wdiole of the above is a translation of Lasch's origii>al 

 description in Linnea, I.e. 



Fries' description of what he considers to be M. excisa 

 differs in some respects from the above, as admitted by him 

 (Icon., p. 88), and he there also says that his fungus may be- 

 distinct from that of Lasch. 



Scotch specimens in the Berkeley herbarium are the only 

 ones collected in Britain so far as I know, and these pre- 

 sumably agreed with the Friesian idea of the species; hence,, 

 whether the two are identical, or if not. which species these- 

 specimens represent is at present uncertain. 



Mycena psammicola. B. & Br. 

 Smell strong, but not nitrous. Pileus about \ in. across,, 

 flesh tliin, almost hemis2)lierical, hygrophanous, brown^
