' Htdnum FEABELiiFOiiME : imbricatum, coriaceum ; pileis spathulato-fla- 

 belliformibus, zonatis, hirsutis; hymenio ochraceo ; aculeis loiigiusculis acutis 



carneis, siccis ochraceis. Berk. in Hook. Land. Journ. Bot., vol. iv. p. 306. 



Pilei imbricated, laterally confluent, half an inch broad, three-quarters of an 

 inch long, spathulato-flabelliform, fixed by a narrow base, which is mostly 

 more or less distinct, coriaceous, clothed with white or slightly tawny short 

 wooly hairs ; hymenium bordered; aculei acute, soinetimes slightly compressed 

 above, flesh colored, ochraceous when dry. Allied to H. ochraceum. 



^ Htdnum stratosum : pileis resupinatis, margine libero, demum stratosis, 

 e processibus rigidis ramosis extus stuppeis formatis; aculeis longis, rigidis, 

 acuminatis, spadiceis, hie illic cinereis. Berk, in Hook. Land. Journ., vol. iv. 



p. 307. Pilei resupinate, with a narrow lobed border, spreading for three 



or four inches over the matrix, consisting of repeatedly branched, rigid, brown 

 processes resembling some Cornicularia, which are clothed above with gray, 

 or ferruginous tow-like fibres. Aculei rather long, rigid, sharply acuminate, 

 brown varying to cinereous, at length stratose. This is one of the most re- 

 markable species with which I am acquainted. It resembles in many respects 

 H. parasiticum, but has not, like that, a coriaceous pileus. The whole sub- 

 stance, indeed, consists merely of rigid branched processes, which are partially 

 covered above with coarse pubescence, so that the pileus might perhaps be 

 described as repeatedly branched. These processes, however, are combined 

 into a lobed stratum. I do not know any other species with which it can be 

 compared, except perhaps, as Dr. Montagne suggests, his H. pteruloides, but 

 that he is now inclined to consider as merely a state of Trametes hydroides, 

 whereas the present is a perfect fungus. 



" Htdxum Ohiense: resupinatum, membranaceum, amatrice hicillic sece- 

 nibile, pallide flavum ; aculeis longis, acutissimis, aquoso pallido-fiiscis, sub- 



fasciculatis. Berk, in Hook. Lond. Journ., vol. iv. p. 307. Spreading for 



several inches, entirely resupinate, membranaceous, partially separable from 

 the matrix ; aculei somewhat fasciculate, one to two lines long, of a watery- 

 pale brown, very slender at the apex. Resembling Hydnum Fernandesiumf 



Mont., from which it differs in its shorter, less crowded aculei. The margin.
