Hone: Minnesota helvelline^e. 315 



M. esculenta occurs in such varied sizes and forms in all of the 

 material which I have examined, I consider that if these are M. 

 conica, that they are only a form or variety of M. esculenta and 

 not a distinct species. Plate I., Jigs, 3-6, show photographs of 

 both forms. 



The specimens agree with Thuemen Fungi Austr. 12, 13, 

 where the spores measure 14—22 mic. x 6-12 mic (12 contains 

 paraphyses measuring 10 mic. at tip and branched) ; Rathay 

 Fl. Exsicc. Austro-Hung. 1572, in which the spores measure 

 20 X 12 mic. ; D. Saccardo Mycoth, Italica, 507, in which the 

 spores measure 14—18 x 10-12 mic.

M. crassipes differs from M. esculenta in its greater size, up 

 to 7.5 in. high, yellowish color and very uneven surface. The 

 ribs also are very acute at the edge and thick at the base while 

 in M. esculenta they are even and very obtuse at the edge.
