Cantharellus confluens

[ Basidiomycota > Cantharellales > Cantharellaceae > Cantharellus . . . ]

by Michael Kuo

If you want to tell me this species is dubiously separated from Cantharellus lateritius, I won't argue with you--much. Virtually the only feature distinguishing the two species is the fact that in Cantharellus confluens, as the name suggests, the mushrooms are often confluent; stems give rise to more than one cap-like structure. In Cantharellus lateritius this does not usually happen. Both species have a smooth to wrinkled undersurface, and microscopic features are virtually identical. To my knowledge no DNA study has been published in which Cantharellus confluens is considered.

Description:

Ecology: Mycorrhizal with hardwoods; growing alone, scattered, or gregariously; summer; southern Appalachians, southeastern United States, and Mexico. The illustrated and described collection is from Ohio.

Fruiting Body: Up to 10 cm high and 8 cm across; usually with two to several cap-like structures arising from one or more individual or conjoined stem structures.

Individual Caps: Flat, becoming centrally depressed but without developing a perforated disc; fleshy; bald or nearly so; dry; orangish yellow; the margin fairly thick, becoming wavy to lobed or irregular.

Undersurface: Running down the stem; smooth or with shallow wrinkles or, near the margin, somewhat veined; colored like the cap or paler; bruising and staining dark yellow.

Stem: Up to 4 cm long and 2.5 cm thick; tapering to the base; dry; colored like the cap or paler; fleshy (not hollow); bruising and staining dark yellow.

Flesh: Whitish; soft; unchanging when sliced.

Odor and Taste: Taste not distinctive; odor fragrant and sweet.

Spore Print: Pale yellow.

Microscopic Features: Spores 7-9 x 4-5 µ; ellipsoid; smooth; inamyloid; ochraceous in KOH; often uniguttulate. Basidia to about 70 x 8 µ; 2-6-sterigmate. Elements from cap surface 5-10 µ wide; hyaline to faintly ochraceous in KOH; clamped; terminal cells subclavate.
