Abstract
The ascospores of Peziza brunneoatra germinate only after being heated to 55[degree] C for 30 min. on 2% agar containing 10 ppm furfural. Less than 1% of the spores germinate following this treatment. Single ascospore cultures grow rapidly on potato-carrot agar at 22[degree] C. Obovate to oblong-elliptical, hyaline conidia are borne on broad denticles on the surface hyphae or at the ends of short, upright branches. The conidial state is not formally assigned to a form-genus. Conidium-derived germlings are very slow growing for 1-2 weeks or longer at 22[degree] C. A physiologic inhibition may have to be overcome before rapid growth by conidium-derived germlings is possible.
