Brief Description: [See More | Edit]

Original description:

Hygrophorus conicus (Fr.) Fr. var. atrosanguineus Grund & K.A. Harrison var. nov.

Pileus 1.7-7.0 cm broad, obtusely conic when young, subumbonate becoming subconic with broadly arched and rounded margins; surface dry, appressed fibrillose-silky, subglabrous, slightly viscid when wet; margins at first entire, becoming incised, lobed and rimose; color dark blood-red (10-D-8) to (10-E-8), becoming black when handled or bruised, soon blackening after picking; context thin, fragile, concolorous with pileal surface, becoming black when cut or bruised; taste none; odor strongly aromatic, pleasant.

Lamellae adnexed; color “Wax Yellow” to “Salmon Color,” rarely “Ochraceous Salmon” in young specimens, becoming “Olive Ochre” at maturity, blackening upon bruising.

Stipe 4.5- 10 cm long, 3-10 mm thick, equal, strict, fragile, splitting longitudinally, slightly twisted, becoming hollow; surface subglabrous to minutely fibrillose, dry to moist, not viscid; color “Bittersweet Orange” to “Wax Yellow,” then pallid at base, blackening where handled; context fibrous, yellow or concolorous with surface, bruising black.

Spores 8-10 X 5-6.5 microns (um), smooth, subellipsoid. Basidia 35-40 X 8-12(13) um, fourspored. Pleurocystidia and cheilocystidia lacking. Lamellar trama parallel, hyphae 7-15 um broad, lactifers present. Pileal surface an epicutis, not reviving in 3%, KOH from dried material, clamps present on hyphae of pileal cuticle, context and lamellae.

Singly in needle duff, in hemlock woods.

This rare new variety is striking because of the deep blood-red color of the pileus. It also differs from H. conicus var. conicus in that it has a strong aromatic odor whereas the typical variety is reported to have no distinctive odor (2, p. 110).
