Xylaria longiana is a scrawny species of Xylaria, virtually indistinguishable from the better known Xylaria hypoxylon, except for having smaller spores. It grows on the wood of oaks in eastern North America, and its spores feature a straight germ slit that extends nearly the full length of the spore.


Ecology: Saprobic on decaying wood and bark of oaks; growing alone or gregariously; causing a soft rot; spring through fall; eastern North America (exact range uncertain).

Fruiting Body: 2-8 cm tall; up to 7 mm thick; sometimes with shared bases; cylindric to irregular, with a pointy tip--or with flattened and/or branched tips; whitish becoming black; surface smooth or distinctly roughened and pimply at maturity; flesh white and tough.

Microscopic Features: Spores 9-11 x 4-5 µ; smooth; widely fusiform; with straight germ slits that run nearly the length of the spore.
