Genus Xylaria Hill ex Schrank

[dead man's fingers and a handful of relatives]

Identification of species is best done with the aid of a hand lens or dissecting scope for viewing surface morphology and a microscope for measuring spores and germ slits.

Taxon Details and Links

  • Xylaria Hill ex Schrank, Baierische Flora 1: 200 (1789). Type: Xylaria hypoxylon (L.) Grev., Flora Edinensis: 355 (1824).
The west coast form of Xylaria hypoxylon could be considered a variety or a separate species from the European species. NOTE: the papers earlier than 2009 have the wrong concept for Xylaria hypoxylon. See Persoh et al. (2009) for corrected concept of Xylaria hypoxylon, and see Fournier et al. (2011) for X. vasconica in eastern USA.
