Observation 208428: Xylaria Hill ex Schrank
When: 2015-05-29
(45.2295° -121.6999° 1200m)

Notes: Xylaria… with a sclerotium?

Note how groups of fruiting bodies arising from the same tuber show distinctly different stages of development. Those that appeared to be mature, and thus good candidates for observing spores, turned out to be overmature and without spores, suggesting multiple flushes of fruiting bodies at different times from the same overwintering structure.

In some FBs (particularly the largest) the demarcation of carbonaceous Xylaria tissue and potato-like tuber is clear. In others, the transition is more gradual. Also note both the grenish-blue cast on the sterile, lower portion of some of the stromata, as well as the apparent insect damage (termites?), both shown in image three.

An all around awesome Xylaria, and quite possibly an undescribed species. Roo will have the final say.
