Brief Description: [See More | Edit]

Pileus 1-3 cm broad, obtuse with a decurved margin, expanding to
plane with a slightly depressed disc or merely convex, sometimes with
a low obtuse umbo, dark purple drab when moist, fading to cinereous
on margin and a tinge of cinnamon buff on disc, surface glabrous,
viscid, hygrophanous. Context with a strong odor of freshly husked
green corn, taste mild.

Lamellae decurrent, pale purplish drab young, becoming dingy
buff in age or on drying, close to sub distant, narrow.
Stipe 3-4 cm long, 3-5 mm thick, equal or nearly so, surface dry,
dull white over all and unchanging when bruised, when dried pale
tan, solid.

Spores 5-6.5 ( 7) X (3..5 )4-5.5 IL, broadly ellipsoid to subglobose,
rarely globose, thin-walled, hyaline in KOH, yellowish-hyaline in
Melzer’s reagent. Basidia 4-spored 38-55 X 6-8 IL (occasionally
2-spored). Pleurocystidia and cheilocystidia none. Gill trama intricately
interwoven, hyphae 4-7 IL broad, hyaline to dingy in KOH,
yellowish-hyaline in Melzer’s reagent (no dark granules present).
Cuticle a zone of gelatinous hyphae 1.5-2.5 IL broad, the zone
60-100 IL thick, originating as a trichodermium but the hyphae greatly
elongating and becoming appressed, hyaline in KOH and Melzer’s
reagent. Pileus trama of subparallel, radially disposed hyphae, 4-10 f1
broad. Clamp connections present, usually small.

HABIT, HABITAT, AND DISTRIBUTION-Scattered in mixed conifer hardwood
forests, Washington and Michigan, September to October.
MATERIAL STUDIED-WASHINGTON: Bigelow 16 (Smith 47958, type,
from Lower Tahoma Creek, Mt. Rainier National Park, Sept. 27,1955),
Stuntz (Smith 31393). MICHIGAN: Smith .50850.

OBSERVATIONS-This species can be easily distinguished in the
field by the odor of fresh green corn. H. pallidus and H. subviolaceus, the most closely related species, have no odor and the taste of their
flesh is mild or bitter finally. The white stipe showed no yellow tints
even after handling, a character of H. lacmus Fr. However, this is the
nearest to H. lacmus of any North American species we have studied.
In the dried specimens the cap has retained the purplish-fuscous tone
over the marginal area, but the disc, the gills, and the stipe show
varying tones of cinnamon buff to darker tan.
