NOTES
Pouzar (1985b) resurrected Nitschke's Hypoxylon aeneum and discussed it in detail. Nemania aenea var. aenea can be separated from its two varieties, var. aureolutea and var. macrospora, by having conspicuous ascospore germ slits. In addition, cultures of N. aenea have hyaline, inflated chlamydospore-like cells and grow faster (Petrini & Rogers 1986). Var. aureolutea differs from var. macrospora in having shorter ascal stipes, slow-growing, orange colonies, and smaller perithecia 0.3-0.4 mm diam. Nemania subaenea differs in having the ascospore germ slit on the dorsal side.The "Barron isolate" of Hypoxylon serpens in Petrini & Rogers (1986) is known only from an isolate obtained from soil in Canada. It produces fertile perithecial stromata in agar culture. It has an ascospore morphology resembling that of N. aenea. However, it has larger perithecia and a darkened area surrounding the ascospore germ slit (and see "Taxa of Nemania that produce the teleomorph in agar culture" ).
