266 SECTION HYGROPHORUS 



with a mediostrate of narrow (3-5 /x), parallel hyphae. Cuticle a broad 

 gelatinous zone, the upper portion (200 /a) of clear gelatinous sub- 

 stance, the lower portion a turf, or ixotrichodermial palisade, of slender, 

 erect hyphae, 90-130 X 2-4 fx. No hypodermium differentiated. Pileus 

 trama homogeneous, of loosely interwoven, radial hyphae. Clamp con- 

 nections present on the hyphae of the pileus trama and gill trama. 



Habit, Habitat, and Distbibution — Gregarious under oak and 

 hickory or in brush along roadsides, Iowa, Michigan, Ohio, Tennessee, 

 and Georgia, September-November.

Obsebvations — This species is related to H. pudorinus but has 

 brighter colors; the pileus is salmon-buff to cadmium orange, the lamel- 

 lae are sea-shell pink; the spores are slightly narrower; and the gluti- 

 nous veil is thick and persistent. Finally, the squamules on the stipe 

 apex, when dried, are pale orange, never as reddish dots as in H. pudo- 

 rinus. In H. subsalmonius the cuticle is a striking ixotrichodermial pali- 

 sade.

Pileus 4-7 cm broad, obtuse, at maturity slightly umbonate, some- 

 times plane and with a decurved margin, "tawny" to "cinnamon brown" 

 on the disc, paler tawny toward the whitish margin, glutinous, more 

 or less fibrillose streaked beneath the gluten, margin cottony tomentose 

 and often beaded with drops of moisture. Context white, thick on the 

 disc, firm; taste mild, odor of almonds when cut or bruised. 



Lamellae bluntly adnate but soon short decurrent, pure white, 

 close to subdistant ( 58-70 reach the stipe ) , equal, narrow ( 3-4.5 mm ) . 



Stipe 8-10 cm long (3-5 cm in alpine forms), 10-15 mm thick at 

 the apex, pure white over all or the base discolored slightly, gradually 

 tapered to a long pointed subradicating base, solid, lower portion gluti- 

 nous from the remains of a gelatinous universal veil, appressed fibrillose
