Fig. specimens: Hjallese, solitary on the petiole of dead leaves 

 of Quercus (rarely on Salix capræa), Sept. 1898. Not rare, but 

 always solitary. 



This little tiny plant is easily overlooked or mistaken for a 

 small Mycena (from which it is most easily recognized by the 

 bay-brown stem). It appears to be very nearly related to M. 

 saccharinus Batsch, from which it differs by broader gills, sul- 

 cate cap without papilla and darker stem. My plant deviates 

 from the description of Quélet by having the lower portion of 

 the stem sparsely clad with long, woolly, minute hairs (not 

 tomentum) and by larger spores (Quélet says 6 — 7 u). By these 

 two characters it approaches M. saccharinus which seems to be 

 intermediate between M. recubans and M. epiphyllus. 



20. M. epiphyllus Fr. (M. squamula Batsch). 



Spores 10 x 4 J / 2 M or 10—12 x 3 x / 2 — 4 u, pipshaped-lanceolate. 

 Cvstidia awlshaped (free portion about 30 u long). Hairs on 

 stem 250—600 u. 



Fig. specimens: Hjallese on petioles and dead shoots of 

 Populus canadensis, Oct. 1896. Rather common, often numerous, 

 especially on leaves and petioles of Fraxinus, on boggy ground. 



For figures of spores, cystidia etc. vide the plate.
