Trametes ohiensis Berk. 



Dead wood of deciduous trees and specially on chestnut rails. 

 Howland island near Savannah. October. This species is not 

 sharply separated from T. scutellata (Schw.). It is generally 

 larger and more strongly ungulate and not so black when old. The 

 point of attachment is often more prominent. It is considered a 

 form of the same species by some, but the two are easily distin- 

 guished by the eye. 



Hydnum populinum n. sp. 



Resupinate, effused, the subiculum thin, minutely floccose, becom- 

 ing submembranaceous, adnate, white or whitish, the naked margin 

 very thin, white; aculei scattered or crowded, very short, obtuse, at 

 first papilliform, becoming half a line long, terete or compressed by 

 the confluence of two or more, white, sometimes with a faint pinkish 

 tint; spores white, elliptic, .00024 to .0003 of an inch long, .00012 to 

 .00015 broad. 



Dead bark of poplar, Populus tremuloides Mx. Ganse- 

 voort. September. It forms patches 2 to 4 inches long. The aculei 

 are scattered near the margin, crowded in the center. 



Hydnum combinans n. sp. 



Subiculum effused, very thin, floccose farinose, adnate, indeter- 

 minate, whitish; aculei scattered and whitish on the margin of the 

 subiculum, crowded, subfasciculate and tinged with creamy yellow 

 elsewhere, narrowly conical, rather tough, short, subobtuse and 

 ciliate at the apex; spores subglobose, .00012 to .00016 of an inch 

 broad, containing a single shining nucleus. 



Decaying decorticated wood of some 'deciduous tree. Warrens- 

 burg. October. 



This species forms very thin patches several inches in extent. The 

 aculei are often united at their bases as in the genus Irp ex, and 

 this union is sometimes formed in such a way that the aculei stand 

 in circles and simulate the dissepiments of pores as in the genus 

 Poria. Their shortness and blunt ciliated apexes indicate a close 

 relationship to the genus Odontia. This combination of charac- 

 ters belonging to three genera has suggested the specific name here.
