GoMPHiDius GLUTINOSUS Fr. (Plate 12). — There are good 

 specimens from Bresadola at the New York Botanical Garden, 

 and typical plants from Sweden in the Atkinson Herbarium. 

 The principal point to be brought out here is that the cystidia 

 are not abundant. In fact in some mounts it is difficult to 

 locate them. In overmature and dried plants they are frequently 

 shriveled, so that observations must be carefully checked. The 

 cystidia of this species also appear to be less cylindrical than in 

 many of the others. The caps are usually quite large, and the 

 stems stout and long. It may be said to be the largest species. 



GoMPHiDius GRACILIS Berk. — I have a few collections from 

 the mountains of Washington which are referable to this species. 

 There are, however, slight differences and further notes are 

 needed. I have seen no European specimens. Our western 

 plants have longer and stouter although rather more slender stems 

 than described for the European species. The spores of the 

 western plants measure 15-18 x 5-6 /x, and the cystidia are 

 abundant. 



GOMPHIDIUS MACULATUS Fr. — I have found no facts which 

 make it necessary to change my account of this (8, p. 170). 

 The comments given with that description on other species (I.e.) 

 are, however, revised in this paper. 



GOMPHIDIUS NIGRICANS Pcck. — This is an eastern species, 

 seldom collected. (See remarks on p. 114.) 



GOMPHIDIUS ROSEUS (Fr.) Quel. — (See remarks under G. 

 stibroseus.) 



GOMPHIDIUS TOMENTOSUS MurriU (Plate 14). — (See remarks 

 under G. oregonensis.) The following descriptive data may be 

 added to Murrill's account (Mycologia 4: 307. 1912). Pileus 

 3-7 cm. broad, obtuse, sometimes actuely subumbonate, the thick 

 pellicle separable and slightly viscid in wet weather, "ochraceous- 

 buff" (Ridg.), darker when wet and then "vinaceous- tawny" 

 to "wood-brown" (Ridg.), deeper ochraceous when dry; flesh 

 thick on disk, abruptly thin on margin, whitish to ochraceous, 

 shot through with "pinkish-buff" hues. Gills close to sub- 

 distant, 6-8 mm. broad in the middle, "ochraceous-buff" to 

 "ochraceous-salmon" (Ridg.), at length sooty-brown. Stem 

 6-12 cm. long, 8-15 (20) mm. thick, rather firm and rigid, con-
