1-5-3 cm. long, 2 mm. thick, fibrillose, paler in colour than the 

 pile.us.

Berkeley was mistaken in considering the present species as 

 belonging to his genus Laccaria, as I have examined his tvpe 

 specimen, also Colenso's New Zealand specimens, both of 

 which have elliptical spores, as described above. Cooke 

 evidentl}' did not examine Berkeley's specimens, but copied 

 his mistake, and printed it in Austr. Fung, p. 17.

 no. 869. 



Pileus convex, then expanded, obtuse or at length obtusely 

 umbonate or gibbous, pale i3esh-colour when moist, whitish 

 when dry, margin at first incurved, then expanded and slightly 

 striate, 5-8 cm. across; flesh thin, rather flexible; gills ad- 

 nexed at first, soon free, very closely crowded, narrow, plane, 

 tinged flesh-colour, then whitish ; spores elliptical, 7-8 x 3-5^; 

 stem 5-10 cm. long, 2-4 mm. thick, rigid, fragile, hollow, 

 slightly thinner upwards, rarely flattened, very glabrous ex- 

 cept at the base, even, rufous or brown, wall of cavity of stem 

 glabrous.

Care must be taken not to confound the present species 

 with Marasmius erythropus. (See note under the last-named 

 fungus.) 



26. Mycena, Fries. 



Pileus thin, regular, campanulate, then expanded, usually 

 striate, margin at first straight and embracing the stem ;
