Ascomycetes of New Zealand 8.Xylaria

Abstract
A floristic monograph of the genus Xylaria (Fungi, Ascomycetes) in New Zealand is presented. Nineteen taxa are recorded including one new species, X. wellingtonensis; two new varieties, X. luteostromata var. macrospora and X. theissenii var. macrospora; and two unnamed taxa related to X. filiformis. Cultural characteristics and anamorphs are described for most of the taxa. Most species of New Zealand Xylaria differ, often subtly, from the same species found elsewhere. These differences are recorded or discussed in the notes following formal descriptions of taxa.
