G. retispora Cain, distinguished by means of the large angular pits in the ascospore wall was isolated in culture from seeds of Swiss chard from Holland and from apple twigs in Quebec. G. tetrasperma Dowding has been found in moist chambers on dung from Ontario, Quebec, Venezuela, and Germany and isolated from seeds from Quebec.
