Endogone in Canadian Rodents

Abstract

to him by Dr. William Jellison of the Public Health Service at the Rocky Mountain Laboratory in Montana. It was a preparation of stomach contents of a mouse. The slide contained one or two large, goldenbrown, thick-walled, stalked spheres measuring up to 120 /x. Dr. White identified these bodies as spores of the Phycomycete, Endogone. He fetched from his herbarium yellow biscuit-shaped Endogone sporocarps about 2 cm across, which had been collected from beneath the soil. Presumably the mouse, when it was trapped, had been eating similar microtruffies.
