798 THE AGARICACEAE OF MICHIGAN 



stained in moist weather, the tendency for the white gills to assume 

 a flesh tint and the size of the spores. The stains on cap and 

 gills and base of stem are dingy yellow, purplish-brown or dark 

 ferruginous. At other times, especially in dry places, the pilei 

 become silvery-shining and scarcely stained. In mounting a sec- 

 tion of the gills the large 'mature spores with homogeneous con- 

 tents sink to the bottom of the water on the slide. The immature 

 spores are subspherical and contain a large globule which is more 

 prominent than the wall of the spore and accounts for the fact 

 that to some observers the spores look spherical. Patouillard re- 

 ports that a common variety has 2-spored basidia; I have not found 

 it. M. liaematopa, which becomes stained in the old stage must 

 not be confused with this species. Occasionally the stem is striate 

 but this form differs from M. polygramma var. albida in the lack 

 of cystidia. and in our territory by the different colors. 



Var. calopus Fr.

Like M. galericulata, except That the gills are adnexed, the stem 

 striatulate and coherent or proliferous at base, joined together 

 and covered by rusty or brown strigose hairs, elsewhere rufous- 

 bay color and shining. Spores as in M. galericulata. No cystidia. 

 The appearance of the stem reminds one of that of Marasmius co- 

 in t ere ns, but the pileus, etc., are very different.
