U.S.A.: South Carolina, Santee Canal, 5.1854, Ravenel, H.W. 1846, wood of Alnus, as Hypoxylon xanthocreas (FH, ISOTYPE of Hypocrea viridirufa).

A penzigioid Xylaria. Hypoxylon peckianum Sacc. and H. xanthocreas Berk. & M. A. Curtis are synonyms. The conidiophores arranged in palisades on the stromatal surface are typical of Xylaria. Saccardo (1882a) mentioned that this fungus has conidiophores covering the stromata in the description of H. peckianum Sacc. Xylaria badia Pat. [= X. timorensis C. G. Lloyd], frequently associated with monocots, is an Asian counterpart of this fungus. Both have a yellowish stromatal interior, a discoid to cuneate ascal apical ring, and nearly equilateral ascospores with a less than spore-length germ slit.
