 Remarks:Our material is not in very good condition, and portions of the stromata are either too young or too old (red and grey-brownish examples – Fig. 9B). The first of these contain only immature perithecia, whereas the latter display only scanty ascospores. The stromata are somewhat similar to those in Hypoxylon crocopeplum Berk. & M.A. Curtis, which is also initiated as brightly colored patches, often covered by conigiogenous structures, but in H. crocopeplum the young stromata are lemon-yellow (sometimes with an orange tinge). Both species are characterized by the same range in ascospore size, have similar colors of KOH-extractable pigments and possess stromatal granules with similar tinges of color, but typical stromata of H. crocopeplum (Fig. 9A) have a rather characteristic granular appearance because of the prominent perithecia. The same kind of stromata can be seen in the photograph of H. crocopeplum from the Great Smoky Mountains National Park (Vasilyeva et al. 2007, Fig. 5, photo by A.N. Miller).
Hypoxylon crocopeplum has been reported from Thailand (Whalley et al. 1995; Okane et al. 2008; Phosri et al. 2008) and is supposed to be widely distributed in the tropics and subtropics. However, the "typical form" of H. crocopeplum with its fairly conspicuous perithecial mounds is observed mostly in eastern North America (Ju & Rogers 1996). Many other forms that have been collected seem to be atypical and might well belong to different species or varieties.
