than the rest of the pileus. From Inocybe eutheloides 

 Pk. it may be distinguished by its lamellae and white stem. 



Inocybe rimosa (Bull.) Fr. 



CRACKED INOCYBE 



Sylloge 5:775 



Pileus fleshy, thin, broadly conic or campanulate becoming ex- 

 panded, obtuse or umbonate, silky fibrous, radiately cracking on 

 the surface, yellowish brown ; lamellae subclose, adnexed or nearly 

 free, whitish becoming tan color or subf erruginous ; stem equal, 

 firm, solid, mealy at the top, nearly glabrous, subbulbous, 

 whitish; spores ellipsoid, even, 10-12 x 5-6 ft, cystidia very rare, 

 60-65 x I 5 _I 8 //.. 



Pileus 2.5-5 cm broad ; stem 2-5 cm long, 4-6 mm thick. 



Ground in woods and open places. Albany, Franklin and Ulster 

 counties. August and September. 



This is a very variable species but one which is generally recog- 

 nizable by the radiately cracking of the surface of the pileus. 



Var. parva Pk. Very small ; the pileus rarely more than 2 cm 

 broad, the cuticle obscurely cracking or sometimes continuous. 



Var. cuspidata Pk. Pileus with a very prominent narrow 

 subacute or cusplike umbo. 



Inocybe eutheles (B. & Br.) Sacc. 



MAMMILLATE INOCYBE 



Sylloge 5:776 



Pileus thin, campanulate becoming expanded, distinctly umbonate, 

 silky, shining, subsquamulose, pale fawn color; lamellae rather 

 narrow, adnate, pallid becoming subferruginous, whitish crenulate 

 on the edge; stem slender, solid, equal, fibrous, pallid or 

 whitish; spores ellipsoid, even, 10-15 x 6-8 p., cystidia very rare, 

 60-65 x : 5~ 2 ° '•'■ • 



Pileus 2.5-4 cm broad ; stem 3-6 cm long, 2-3 mm thick.

This species has been found but once and is apparently very rare. 

 The European plant is said to have a farinaceous odor and spores 

 7-10 ,"- long. In our plant the spores are longer and the odor was 

 not noticed, but in other respects the agreement is fairly good.
