Live-and dead-spore inoculum of Endogone gigantea showed that endotrophic mycorrhizal infection rather than contaminants stimulates the growth of hardwood seedlings. Seedlings inoculated with live spores became infected and generally grew much faster than those inoculated with spores killed mechanically. Cross inoculation with small amounts of surface-sterilized roots demonstrates that yellow-poplar, white ash, box elder, and sugar maple, like many other plants, can be nonselectively infected.
