Trametes merisma n. sp. 



Pileus coriaceous, fibrous, tough, commonly deeply divided into 

 several pileoli, uneven, tuberculose, colliculose or diminutively pro- 

 liferous, subpubescent, white or whitish, flesh pure white, the margin 

 obtuse, sterile beneath; pores minute, 2-3 in a millimeter, develop- 

 ing from the center toward the margin, white, the edge of the 

 dissepiments at first obtuse; stem like base short or none; spores 

 not seen. 



Pileus 2.5-7 cm broad. 



Decaying prostrate trunks of beech trees, Fagus grandi- 

 folia Ehrh. Fine. August. 



This singular fungus sometimes develops from the lower surface 

 of the trunk, in which case a tubercle first appears and the pendent 

 pileus develops from it and is centrally attached to it by the apex. 

 The context of the pileus is similar to that of species of Polystictus, 

 but the character of the pores indicates a closer connection with 

 Trametes. 



Pileus coriaceous, fibrosus, lentus, vulgo in pileolos paucos pro- 

 funde divisus, asper tuberculosus colliculosus vel leviter proliferus, 

 subpubescens, albus albidusve, carne Candida, margine obtuso, infra 

 sterile; pori minuti, .3-5 mm lati, a centro ad marginem patescentes, 

 albi, dissepimentis obtusis, stipes brevis vel nullus. 



Trichosporium variabile n. sp. 



Widely effused, forming thin indefinite blackish patches; hyphae 

 prostrate or suberect, simple or branched, continuous or rarely 

 septate, 4-5 t* in diameter, brown by transmitted light or partly 

 hyaline; spores varying from globose to oblong, colored, 6-10 u in 

 diameter or 8-12 x 6-8 <k 



On building paper kept in rolls under shelter. Lyndonville. 

 September and November. C. E. Fairman. 



The species is remarkable for the variability in the size and 

 shape of the spores. They are intermingled, but the oblong spores 

 are more numerous than the globose. It differs from Tricho- 

 sporium chartaceum (Pers.) Sacc. in its much larger 

 spores. 



Late effusum, stratum tenue indeterminatum nigrescens formans ; 

 hyphae repentes suberectaeve, simplices ramosaeve, continuae vel 

 leviter septatae, 4-5 f* crassae, fuscae seu partim hyalinae; sporae 

 fuscae, globosae, 6-10 /1 latae, vel oblongae, 8-12 x 6-8 <«.
