Lepiota cyanozonata Longyear. Described in .3d annual report of Michigan 

 Academy of Science, 1901, as follows: Pileus 1-1.8 cm., broad, thin except at the 

 disc, conico-convex becoming expanded and broadly umbonate, minutely fibrillose 

 when young, soon glabrous, margin slightly uneven, creamy or pinkish white with 

 a narrow zone of light blue near the margin, brownish tan when dry; gills free, 

 ])ut close to the stem, scarcely crowded, thin, soft, whitish, becoming dingy 

 l)rown on drying. 



Stem 2-:3 cm. long 2 mm., thick, equal, apex smooth, minutely silky, scaly below 

 narrowly fitulose, whitish, attached by strigose fibers; spores white, globose 6-8 

 microns. 



Growing on decaying sticks on ground in woods. Leslie, July 23, 1900. 



Considerable doubt is felt as to the true generic position of this little fungus as 

 it seems somewhat intermediate between Collybia and Lepiota. One small unex- 

 pandad specim.en possessed a delicate fibrous veil similar to that found in the 

 ■•^eniTs Cortinarius, but only the merest remains of it could be found in 

 mature specimens. The flesh of pileus and stem, however, appears to be distinct, 

 and becomes brownish where bruised. Its striking feature is the delicate blue 

 marginal zone which is suggestive of the specific name.

leptonia asprella Fr. This species was found in some abundance in the cedar 

 swamps growing in the moss. Beardslee. 



Jjeptoi-'ia formosa Fr. Growing in cedar swamps, frequent. Beardslee. 



I.eptcmia rosea Longyear. Described in 3d annual report of Michigan Academy 

 ■of Science, 1901, as follows: Pileus 3-3. .5 cm. broad, flesh thin, convex, obtuse 

 and depressed at the disc, not striate, roughened with brownish fibrils on a roseate 

 ground color disc darker; gills adnate with a slight tooth, fi mm. broad, whitish 

 thin flesh-color, not crowded; stem 7-8 cm. long, slender, slightly thickened at apex 

 and base, roseate, base whitened with mycelium, cartilaginous, smooth, sufEed; 

 spores flesh color, angular. 7-8x10-12 microns. 



Burnt soil on a sandy hillside, Kent county, July 14, 1900. 



The slender, erect form and pleasing color make this an attractive looking 

 fungus. The specific name was suggested by the prevailing rose-color of the 

 pileus and stem, this color being modified in places by brownish tints. Only two 

 specimens were found. 



leptonia serrulata Pers. In cedar swamps. Common. Beardslee. 



Marasmius cjimpanulatus Pk. Woods. M. A. C. Summer. 



Marasmius opiphyllus Fr. Decaying leaves in woods.
