Abstract

The mycoparasite Nematogonum ferrugineum (Gonatorrhodiella highlei) was associated commonly with Nectria galligena cankers on Betula lenta in New Hampshire and Connecticut, and was isolated from N. galligena cankers on Juglans nigra from Virginia. In inoculation trials, parasitized isolates of N. coccinea var. faginata and N. galligena spread more slowly than non-parasitized isolates in bark and cambial tissues; parasitized N. coccinea var. faginata produced fewer perithecia.
