Calocera cornea

[ Basidiomycetes > Dacrymycetales > Dacrymycetaceae > Calocera ... ]

by Michael Kuo

Look for Calocera cornea after heavy rains on the barkless, dead wood of oaks and other hardwoods, where it appears as clusters of slick, cylindric fruiting bodies with rounded-off or somewhat sharpened tips. In fact it looks more like a tiny club fungus than a jelly fungus, but microscopic examination reveals the distinctive Y-shaped basidia that characterize members of the Dacrymycetales--a large group within the jelly fungi.

Description:

Ecology: Saprobic; growing scattered to gregariously on the barkless wood of hardwoods (especially oaks); summer and fall; widely distributed in North America.

Fruiting Body: Cylindric, with rounded to sharpened tips; occasionally shallowly forked near the tip; to about 2 cm high and 3 mm thick; smooth and slick; firm but gelatinous; orangish yellow.

Spore Print: White to yellowish.

Microscopic Features: Spores 7-11 x 3-4.5 µ; curved-cylindric; smooth; aseptate or frequently faintly 1-septate by maturity. Basidia Y-shaped; up to 25 x 3 µ.

The similar Calocera furcata grows on conifer wood; its spores are 3-septate. Calocera viscosa is a more robust species (up to 8 cm tall) that is usually branched two or three times
