Cantharellus lateritius

[ Basidiomycetes > Cantharellales > Cantharellus . . . ]

by Michael Kuo

Cantharellus lateritius, often called the "smooth chanterelle," is, in theory, easily recognized: it is a medium-sized to large chanterelle with a smooth to merely shallowly wrinkled undersurface and a single, well defined stem. It is a mycorrhizal partner with oaks in eastern North America, and it usually appears in July.

But specimens that seem to intergrade between Cantharellus lateritius and "Cantharellus cibarius" are not infrequently encountered (see the illustration)--and it is not always easy to decide just how "gill-like" the folds on the undersurface need to be before the line has been crossed between the two species (as currently defined).

Further identification difficulties arise when Cantharellus confluens and Craterellus odoratus are considered. The former species is nearly identical but features stems that often give rise to multiple caps; the latter is a thin-fleshed, fragile species that is truly (rather than shallowly) vase-shaped--like a yellow version of Craterellus cornucopioides; it is briefly described and illustrated on Tom Volk's page for Craterellus fallax.

Description:

Ecology: Mycorrhizal with oaks; growing alone, scattered, or gregariously; summer and fall; widely distributed east of the Rocky Mountains.

Cap: 2-10 cm wide; flat, becoming shallowly vase-shaped with a wavy margin; bald; bright orange-yellow to egg-yolk yellow; bruising reddish brown and occasionally blackening in age at the margin.

Undersurface: Smooth or with shallow wrinkles; colored like the cap.

Stem: 2-10 cm long; 0.5-2.5 cm thick; tapering to the base; colored like the cap or paler.

Flesh: Whitish to yellowish; soft.

Odor and Taste: Taste not distinctive; odor usually strong, fragrant and sweet.

Chemical Reactions: Flesh pinkish gray to gray with iron salts; undersurface dark gray with iron salts.

Spore Print: Pale pinkish yellow.

Microscopic Features: Spores 7.5-12.5 x 4.5-6.5 µ; smooth; ellipsoid; inamyloid; hyaline to ochraceous in KOH. Basidia to about 70 x 7.5 µ; 4-sterigmate. Clamp connections present.
