On hard wood in damp places. Effused for an inch or two. 

 The aculei are often cleft, the tips when fully developed are white 

 and tomentose 



17. H. UDUM, Fr. Subiculum effused, thin, somewhat gela- 

 tinous, agglutinate, glabrous, flesh-color then watery-yellowish. 

 Aculei close, unequal, forked and fimbriate, concolorous. 



On rotten wood of Elm. Very extensively effused sometimes for 

 many feet. The aculei very unequal and more or less fused together 

 and the waxy, uneven subiculum remind one of Radulum. Different 

 patches of flesh-color and yellowish are usually to be seen at the 

 same time in the same specimen. The dried specimens take on a 

 brownish hue. 



.i,''. Siihiculuin byssine or membranaceous. 



18. H. Ohiense, Berk. Subiculum effused, membranaceous, 

 separable, pale yellow. Aculei somewhat fasciculate, long, very 

 acute, of a watery pale brown. 



On rotten trunks and branches. Effused for several irches, 

 membranaceous and partially separable from the matrix. The acu- 

 lei are 1-2 lines long and very slender at the apex. 



19. H. BYssiNUM, Schw. Subiculum byssine, very thin, i)ulveru- 

 lent, somewhat evanescent, ochraceous then bay; the border fibril- 

 lose. Aculei long, distant, subflexuous, very acute, concolorous. 



On rotten wood. It is not circumscribed by a regular border, 

 but fibrils radiate irregularly from the edge of the subiculum. The 

 aculei from a thick base elongate to a very sharp point. 



20. H. ALBoviRiDE, Morg. Subiculum membranaceous fibril- 

 lose, creeping extensively, white. Aculei crowded, very long, sub- 

 ulate, terete, entire, olivaceous. 



On the underside of old logs. The white filmy subiculum 

 runs over the wood and bark and over the leaves and sticks be- 

 neath; here and there are olive colored cushions of spines an inch 

 or more in extent, leaving large white naked spaces. The aculei 

 are 2-3 lines long and taper gradually to a fine point; they are 

 darker after drying. 



21. H. PiTHYOPHiLUM, B. and C. Subiculum effused, byssoid, 

 very thin, farinaceous. Aculei compressed, ochraceous, denticu- 

 late or divided at the apex. 



On dead wood. Effused in small patches. The teeth are 

 rather crowded on the thin subiculum ; on the surface of them are 

 minute granules.
