CLASSIFICATION OF AGARICS 71 



7 l - t-iii. Long, slender, equal, hollow, clothed with <i densi tj 

 velvety tomentum throughout." 



Peck's description, given above, differs from Berkley's in 8 

 cardo, in thai the cap does qo1 have.an umbilicus, and in the much 

 longer and slender stem. No spore-measurements are published. 



Among fallen leaves in woods, on the ground. Ann Arbor. 



Our specimens were verified by Peck. The spines measure 6-7x4 

 in ifi-.. <p\ ;il to ova te, smooth. 



41. Marasmius resinosus (Pk.) Sacc.

I'll.Kl's r» li' iniii. broad, convex, then expanded and depressed, 

 pliant, • tough, dull white, rarely grayish or tawny, sometimes 

 umbilicate or subinfundibuliform, even or subrugulose, glandular- 

 pubescent. FLESH thin, submembranaceus. GILLS arcuate- 

 decurrent, close to subdistant, narrow, white or whitish, often veined 

 or forked, edge llocculose. STEM 2-5 em. long, 0.5-1 mm. thick, 

 slender, equal, tough, cartilaginous, glandular-pruinose, tubular, 

 not striate, while then pallid, attached by floccose base, rarely con- 

 fluent. SPORES oval-lanceolate, 6-7x3-4 micr., smooth, white. 

 STERILE CELLS on edge of gills numerous narrowly clavate, ob- 

 tuse. 30x6-7 micr. ODOB and TASTE mild. 



Gregarious or subcaespitose, attached to grass, sticks, leaves, etc., 



in t'rondose w l<. Ann Arbor. July-September. Frequent locally 



after heavy rains. 



The pubescence of cap and stem is due to minute, Bhorl hairs 

 which arc often glandular-tipped as seen under the microscope 

 When rubbed between the fingers the fresh plant feels resinous. The 

 decurrenl .^ills suggesl an Omphalia, bu1 the reviving and tough 

 substance of the plant are characteristics which place it here. I' 

 was tirst named I/, decurrens by Peck, who happened on specim< 



Which were not ,it nil typical as to the color of the cap. B rdo 



changed the specific name to resinosus, because decurrens wt 

 occupied. Later, Peck named the common form var. niveus, which 

 still later he changed to var. candidisimus. All these names should 

 he dropped, since ih" plant is practically always white.
