122 Mycologia 



Dr. Lane of Portland, who sent the specimens from which Dr. 

 Peck drew his description, wrote Dr. Peck that this species 

 "grows there by the wagon load." Murrill (I.e.) says he "found 

 it common both in Washington and Oregon." Zeller (15) also 

 reports it as "one of the very common Agarics" around Corvallis, 

 Oregon. My experience differs for the localities I visited in 

 Washington and Oregon. At the base of Mt. Hood, G. tomentosus 

 was very abundant, and rarely one could pick up also a few speci- 

 mens of G. ochraceiis and G. suhroseus. In the Cascade range 

 east of Seattle, only G. tomentosus was found. In northern Idaho 

 the latter species also occurred. In the Olympic Mountains, 

 however, in addition to the frequent G. tomentosus, I obtained 

 two solitary-growing specimens of G. oregonensis. The questions 

 then arise, is it G. tomentosus, instead of G. oregonensis, which is so 

 common in these regions, or is each common only in certain 

 localities? The simple process of determining the spore-size will 

 doubtless be sufficient in the future to decide these points. 



GoMPHiDius visciDUS Fr. Columbiana form. nov. 



Pileus 2-6 cm. broad, at first subconic-campanulate then ex- 

 panded-umbonate, subviscid, or viscid in wet weather, color 

 when fresh "auburn," "bay" or "Hay's russet" (Ridg.), some- 

 times with purplish tints, very glabrous, even, shining when dry; 

 margin at first incurved, and cortinate with an evanescent, "apri- 

 cot-buff"" cortina; flesh thick on disk, abruptly thin on margin, 

 tinged pinkish. Gills decurrent, broad in middle, narrowed 

 towards ends, close to subdistant, distinct, none or very few 

 forked, thick, soon "ochraceous-tawny " to "tawny," at length 

 "sepia" or "Prout's brown" (Ridg.). Stem 3-7 (8) cm. long, 

 4-12 (15) mm. thick, subequal or ventricose downwards, or some- 

 what pointed at base, solid, varying when young from "capucine- 

 buff , " or " flesh-ochre " to " apricot-orange, ' 'at length sordid brown , 

 concolorous within, when fresh covered with delicate, appressed 

 fibrillose shreds, glabrescent except at the obsolete cortinate 

 zone at apex, which is colored by the spores. Spores 16-21 (23) 

 X 6-7 (7.5) M, subfusiform, smooth, tinged smoky. Cystidia very 

 abundant, cylindrical, with slender pedicel, hyaline, 120-150 x 

 15-18 IX. Odor and taste none.
