koma Park, Maryland, Shear; M. lichenicola, from North Elba, 

 New York, Peck; M. duhius, from New York City, Murrill; M. 

 sulphureus, from Palm Beach, Florida, Thaxter; M. tomentosus, 

 from Sidney, British Columbia, Macoun; M. hirtellus, from 

 Sharon, Massachusetts, Piquet; M. Farlozvii, from Chocorua,

 River, Idaho, Weir; M. hyssoideus, from Rio Piedras, Porto 

 Rico, Johnston; and M. atrovirens, from Mt. Mitchell, North 

 Carolina, Atkinson. 



New combinations: Merulius deglithens (Berk. & Curt.) Burt, 

 M. terrestris (Peck) Burt, and M. pinastri (Fries) Burt. 



Doubtful and excluded species : Merulius patellaeformis Berk. 

 & Curt, and Poria incrassata (Berk. & Curt.) Burt, comb. nov. 



Merulius hirsutus was described by Dr. Burt from only a frag- 

 ment of the original collection, owing to a delay in sending him 

 the two large collections made near Jalapa, Mexico, one of which 

 was accompanied by field notes and a colored sketch. In spite of 

 this, the description as published leaves little to be desired. Dr. 

 Murrill's field notes, however, are added below : 



Pileus imbricate, sessile, projecting 1-4 cm., 3-5 cm. broad, about 3 mm. 

 thick; surface cottony-white and densely tomentose, white on the margin; 

 hymenium uneven and somewhat zonate-sulcate, ochraceous to ferruginous, 

 consisting of very obtuse, low folds, which disappear near the margin. 



On fallen dead branches in the forest.
