NOTES

Daldinia childiae is probably the most frequently encountered species in the genus. Most collections of this fungus have been identified as D. concentrica. It differs from the latter in having isabelline, hazel, honey, amber, or cinnamon KOH pigments, in lacking fine network of cracks on the stromatal surface, and in having broader conidia produced from a Nodulisporium state with conidiogenous cells that usually proliferate sympodially. Conidial dimensions given in Table 1 of Ju et al. (1997) represent those of several species, including both D. concentrica and D. childiae. Stromata of D. concentrica are usually larger and become black and varnished in age.

Hypoxylon simile C. G. Lloyd was listed in synonymy with D. concentrica by Ju et al. (1997). Its type specimen at BPI is from New Zealand and is in very poor condition. We thus hesitate in using this name to represent such a widely distributed species.
