FUNGI ISOLATED FROM THE FRUITS AND SEEDS OF SOME NORTHERN HARDWOOD TREES

Seed-borne fungi have been reported on or in the fruits and seeds of many horticultural and agronomic plants. There are relatively few reports, however, of fungi borne on the fruits and seeds of forest trees, especially of deciduous trees in North America. Ames (1952) isolated Gleosporium ulmicolum Miles from the fruits of rock elm ( Ulmus thom asi Sarg.) and variegated English elm (U. procem cv. argenteovariegata West.). Shigo and Yelenosky (1963) isolated Coniothyrium sp., Penicillium spp., Aspergillus spp., Alternaria sp. and Trichothecium roseum Link ex Fr. from yellow birch (Betula alleghaniensis Britt.) seeds. In view of these limited reports it was decided to determine further the presence of seed-borne fungi in the fruits and seeds of some northern hardwood trees.
