CLASSIFICATION OF AC.AKK S 



somewhat close, rather broad, broadesl behind, narrow in front, 

 white then pale ochraceous-brown, edge entire. STEM distinct, 2 i 

 nun. long, eccentric to nearly lateral, L-l.o mm. thick, equal, white, 

 pruinose, villose a1 base, somewhal prolonged to the gills. SPORES 



spherical, 5-6 micr. diam., si th, pale ochraceous-brown. ODOB 



and TASTE ao1 noticeable. 



Gregarious, on very rut ten wood. Low swampy woods. Ann 

 Arbor. September. Pound bu1 once. 



The texture is rather firm; the stipitate character separates it 



from C. malachius, ami the globose spores from C. sepiarius. The 

 pileus is marginate behind ami with a minute, floccose tuft on the 



side of the stem. ('. tiliophUa Pk. ami C. hattStellaris Ft. are 



also sa'nl to have a short stem, hut the pilei of these are brown or 

 alutaceous ami their spores art.' elliptical.

PILEUS L-3 cm. broad, reniform to flabelliform, convex, slightly 

 lobed, narrowed into a stem-like base, delicately hairy or glabrous 

 in front, basal halt covered with a <i< 3nse cottony white tomentum, 

 watery-ochraceous when moist. i>< c<>inin<i pale chrome when drying, 

 e\.n on margin. GILLS rather broad, close, thicklsh, converging 

 at the very base, ochraceous-buff, becoming rusty-ochraceous from 

 the spores. SPOKKS spherical. 4.5-5.5 micr.. with a depression or 

 cavity on one side, ochraceous under the microscope. 



Scattered on decaying beech log. Bay View. September. Rare. 



Originally collected at Waynesville, Ohio, in 1844 by Thomas <;. 

 Lea. and named by Berkeley, along with a lisl of other fungi senl 

 to him by the same collector. (See ("inn. Sue. of Nat. Hist.. Vol. 

 5, 1882, p. !!•!». i 



Our plant was at lirst referred to C. ralfsii B. & Br., hut it is 



much more like Lea's plant. The ground color of the pileus ami 

 gills is yellow to ochraceous. ami the peculiar spares add a definite 

 distinguishing character. It is ch.se to c. dorsalis.
