SCHWEINITZIL Pileus dark brown covered with matted 

 tomentum. Context brown, soft, spongy when fresh, brittle when 

 dry. Stipe usually short and thick, rarely central, usually excentric. 

 sometimes wanting. Pores large at first, meruloid, shallow, becoming 

 longer, irregular and often lacerate when old. Spores white in mass, 

 elliptical 4x6, hyaline, smooth. A frequent plant in both Europe and 

 the United States, but growing usually in pine woods. Sometimes 

 quite large, one to two feet in diameter. 



REPSOLDI. Described from Brazil as growing on trunks and having a 

 "gigantic" stem. Spores 5x7, hyaline. Not found by me at Berlin, but tin- 

 description is close to Schweinitzii except the pores are minute. 



PACHYPUS. Known only from unsatisfactory specimens in tin Herbarium 

 of Montague. It ame from Cuba and seems to me to be closely related to 

 Schweinitzii.
