The Mycologk Flora of the Miami Valley, 0. 1 1 



In woods on trunks and branches, common. Pilei imbricated 

 and confluent sometimes to the extent of several inches, the single 

 pilei 1-3 inches in width and projecting an inch or more. The 

 color is a pale or dark brown, drying to brownish alutaceous ; 

 when fresh it has a pleasant fragrance. I'he spines are longer 

 than the thickness of the pileus and yet scarcely reach an eighth of 

 an inch, they are somewhat compressed and are nearly obsolete 

 around the margin. 



13. H. FLABELLiFORME, Berk. Pilei sessile, spathulate flabilli- 

 form, laterally confluent, coriaceous, tawny, hirsute, concentrically 

 sulcata. Aculei crowded, very long, ochraceous flesh-color. 



In woods on trunks and branches, common. The pilei are 

 attaclied by a narrow base or sometimes substipitate, not effuso- 

 reflexed as in the preceding and the following species ; they are 

 often lateVally confluent above and separate at the base, an inch or 

 thereabouts in length, concentrically sulcate or subzonate and 

 longitudinally crisped and wrinkled. The spines are twice as long 

 as the thickness of the pileus. 



14 H. ocHRACEUs, Pers. Pilei effuso-reflexed, coriaceous, 

 thin, zonate, ochraceous. Aculei very small, ochraceous flesh- 

 color. 



In woods on fallen sticks and branches, common. Usually 

 largely resupinate with a long and narrow reflexed margin not half 

 an inch in width; often it occurs wholly resupinate, it then has a 

 narrow, pale, thick tomentose border. 



V. Resupinati. Pileus none. Fungi absolutely resupinate, 

 the aculei straight or oblique according to the situation. 



e. Subiculum thick, fleshy. 

 15. H. CASEARIUM, Morg. Subiculum fleshy-cheesy, thick, 

 extensivly effused, white. Aculei waxy, crowded very long, sub 

 ulate, terete, whitish then pale alutaceous. 



On the lower side of an old hickory trunk. Effused for sev- 

 eral feet, the subiculum nearly half an inch in thickness, contracl- 

 ing in drying and becoming hard and rimose. The aculei are 2-4 

 lines long, oblique, more or less fused together below. 



f. Subiculum zaaxy or subgelatinous. 

 16 H, XANTHUM, B. and C. Subiculum effused, at first white 

 and tomentose, then waxy. Aculei distant, compressed, some- 

 times divided, lemon-yellow.
