1 nun. thick, brown, naked, base white-mycelioid. Spores somewhat 

 almond-shaped, L4-18x6-7 mier., smooth. GYSTIDIA on edge of 

 gills, fusiform, 50-60x8-10 mm. 



On bark of standing trees (like Mycena corticola). ~Sot found 

 with certainty in the State. The description is adapted from Ricken. 



542. Naucoria triscopoda Fr. 



M igraphia, ls<>:'>. 



Illustrations: Fries, Icones, PL 124, Fig. 3. 

 Cooke, 111., PL 458. 



PILEUS 3-10 mm. broad, small, at first conical, then campanulate 

 with a marked acute umbo, striatulate to the umbo, chestnut-brown 

 to rufous-brown, glabrous. FLESH submembranaceous. GILLS ad- 

 nate, ascending, thickish, ventricose, close, ochraceous-cinnamon 

 then darker, edge white-fimbriate. STEM 2-3 cm. long, 1 mm. thick, 

 slender, reddish-brown, darker below, glabrous, hollow, apex pruin- 

 ose, innately silky. SPORES minute, (i-7 x 3-4 micr., rusty-brown, 

 smooth. CYSTIDIA none. STERILE CELLS on edge of gills, 

 slender, subcylindrical, about .">."> micr. long. 



<>n much decayed wood in mixed forests of beech and hemlock. 

 Bay View, New Richmond. September. Infrequent. 



A dainty little plant, well-marked by its shape and color. The 

 descriptions omit the striations of the pileus, but they are well 

 shown in Fries' excellent figures. Ricken has referred it to the 

 genus Galera but without explanation. This is the plant referred 

 to in the list of the 8th Rep. Mich. Acad. ScL, p. 35, under N. euspi- 

 data Pk. (in ed.) which Peck never published. It is clearly Fries' 

 sj ecies.

 seceding, plane, close to subdistant, narrow, cinnamon-brown, edge
