 Ricken, Blatterpilze, Fl. 57, Fig. 1. 



I' ILEUS 6-12 cm. broad, tough, broadly convex, then expanded, 

 obtuse or depressed, tawny-orange or fulvous on disk, yellowish on 

 margin, sometimes paler, with a separable, viscid pellicle, loosely 

 scaly-dotted, glabrescent, even. FLESH whitish, moist, rather 

 thick, tinged yellow under pellicle. GILLS adnate, then emargi- 

 nate or seceding, sometimes subdecurrent or uncinate, medium 

 broad, close to crowded, sulphur-yellow to greenish-yellow, then 

 dingtf-ochre to olive-brown, edge minutely fimbriate. STEM 1-6 cm. 

 long, 8-15 mm. thick, equal or slightly tapering downwards, curved 

 or straight, subbulbous at base, spongy-solid or hollowed by grubs,, 

 at first whitish within and without, tinged yellowish or at base 

 rusty-brown in age, fibrillose. SPOKES minute, elliptical, 5-6 x 

 .'!-:;. 5 micr., smooth, pale rusty-brown in mass. CYSTIDIA very 

 abundant on sides and edge of gills, ventricose, obtuse, 45 x 12-15 

 micr., rarely longer. ODOR and TASTE mild or very slightly of 

 radish. 



Gregarious or subcaespitose. On decaying logs in mixed or 

 frondose, low woods. Bay View, New Richmond. September. In- 

 frequent or local. 



Our plant departs slightly from the accepted characters for the 

 species. It is known by its large size, viscid or glutinous, scaly- 

 dotted, yellow-tawny cap and whitish stem when fresh. The colors 

 of the pileus are shown in the figures of Fries, although a form, 

 such as is shown in Ricken's figure, has been found in the same 

 locality with the Friesian plant. The flesh of both forms is white 

 in the fresh plant. The color of the spore-mass indicates the next 

 section; but it must not be confused with E. spumosa which is a 

 smaller plant, whose cap is not dotted with scales, and whose 

 flesh is greenish-yellow. F. lubrica appears to be limited to the 

 coniferous regions of the State.
