Clavulinopsis corniculata

[ Basidiomycetes > Agaricales > Clavariaceae > Clavulinopsis . . . ]

by Michael Kuo

Clavulinopsis corniculata, with its yellow colors and delicate branching, is fairly distinctive among corals and clubs. Most collections have a mealy odor and taste, and a drop of iron salts on one of the branches produces an olive green color change. Under the microscope, Clavulinopsis corniculata features clamp connections and smooth, nearly round spores with a prominent apiculus.

As an English teacher I am tempted to digress on the rolling dactyls and anapests in "Clavulinopsis corniculata," with scansion identical to Whitman's "Out of the cradle, endlessly rocking," but I'm pretty sure no one cares.
