22. H. iscHNODES, Berk. Suliiculum membranaceous-fibrillosc, 

 creeping extensively, white. Aculei .scattered, distant, subulate, 

 slender, becoming darker. 



On wood and bark of Juglans. The subiculum is composed 

 of a thin membrane of interwoven threads with thicker branched 

 fibrils beneath. The aculei occur in patches with abundant naked 

 space; in places there are only the thick fibers creeping over the 

 matrix. This is an elegant resupinate species, its color all white 

 when fresh. 



23. H,, FALLAX, Fr. Subiculum irregularly effused, thin, villose- 

 furfuraceous, white. Aculei close, deformed, incised, yellowish 

 or whitish. 



On the underside of old Oak logs. Irregularly effused even 

 for several feet, mostly white but yellowish here and there in spots 

 and patches. The aculei are short minute and quite irregular. 



24. H. MUCiDUM, Fr. Subiculum very broad, membrana- 

 ceous, soft, se|)arable, white, the margin and unders'de villous. 

 Aculei close, long, acicular, slender, flaccid, equal, concolorous. 



Upon very rotton wood. The subiculum, a long and wide 

 membrane, soft and tomentose beneath, and sometimes yellowish. 

 The aculei are 2 4 lines or more in length, terete and tapering to a 

 fine point. 



//. Subiculum crustaceous or farinaceous. 



25. H. Fusco-ATRUM, Fr. Subiculum crustaceous, thin, 

 at first glaucous, flocculose, pruinose ; afterward glabrous, ferru- 

 ginous, fuscous. Aculei short, conic-subulate, acute, cervine, then 

 blackish. 



On rotten wood of Beech. In its younger state, somewhat 

 orbicular \-\ inch broad, the margin often byssine ; afterward be- 

 coming confluent and broadly effused. Aculei rather short and 

 not much crowded. 



26. H. ALUTACEUM, Fr. Subiculum longitudinally effused, 

 crustose, adnate, glabrous, pale ochraceous, the border naked. 

 Aculei minute, close, equal, acute. 



On bark and wood of Beech and Maple. Effused for several 

 inches, and separate from but closely adn ite to the matrix. The 

 aculei are very minute and close, and grow out to the very edge of 

 the subiculum.
