Fungus Flora of ML Hood 139 



pinkish buff" to "drab gray" (R.), umbo "fuscous," at length 

 tinged avellaneous, striate-subphcate, striae subdistant, sub- 

 hygrophanous, scarcely fading, glabrous, margin at first straight; 

 flesh submembranous, equal, concolor. Gills ascending, adnate- 

 seceding, rather narrow, without decurrent tooth, subdistant, 

 distinct, white, at length gray-tinted, edge entire. Stem 4-7 cm. 

 long, 1-2 mm. thick, equal, even, glabrous, naked at the apex, 

 pale "echru-drab" to "wood brown" (R.), terete or twisted, 

 sometimes compressed-sulcate, cartilaginous, tough, strict and 

 elastic, with a watery juice, becoming dark vinaceous when crushed. 

 Odor and taste none. Spores 9-11(12) x 5-6(7) ^x, ellipsoid, 

 acute at apiculate end, hyaline, smooth; cystidia none; sterile 

 cells on edge of gills saccate but indistinct ; surface layer of pileus 

 corticate, composed of 3 to 4 rows of subglobose, vesciculose, 

 rather large cells. 



On decayed wood and needle beds of hemlock. Cespitose to 

 solitary. Mt. Hood, Oregon. October 7 and 16. Collected by 

 C. H. Kauffman. 



It belongs to the section Lactipedes by virtue of the rather 

 copious watery juice of the stem, which stains the crushed flesh 

 wine color. In other respects, it could be referred to the Fi- 

 lopedes. In age the drab and fuscous colors of the cap may fade. 

 In addition to the juicy stem it is distinguishable from its 

 relatives by the lack of odor, the narrow, subdistant gills, the 

 spore characters and the absence of cystidia. When growing on 

 wood, the stems may be dwarfed.

Naucoria sideroides Fr.-Ricken 



Naucoria belluloides, sp. nov. — Pileus 8-20 mm. broad, con- 

 vex, obtuse, dry, glabrous, "chestnut" to "hays russet" (R.), 

 not hygrophanous, margin at first involute, then spreading, even 

 when moist; flesh thin, concolor to ochraceous. Gills adnexed, 

 rounded behind, not broad, 3 mm., crowded, "chamois" to 

 "honey-yeflow" (R.), edge entire. Stem 2-3 cm. long, 2-3 mm. 

 thick, equal or tapering slightly upwards, "cinnamon-rufous" 

 within and without, stuffed axis paler, apex pruinose, glabrous else- 

 where, even. Odor none; taste distinctly bitter. Spores broadly
