White Spongy Heart Rot
of
living trees of black ash, oak, maple and birch;
does not decay dead trees. Heartwood in
upper portion of trunk is reduced to soft spongy
yellow or white mass. Shelf sporophores, up to
10 inches wide, have dark brown, coarse, velvety
to hairy upper surface and golden brown under-
surface, turning dark brown with age. They are
formed at branch stubs, frost cracks, or trunk
cankers.

upper surface and brilliant yellow underneath,
formed in overlapping clusters. When old they
are hard, brittle, dirty white (see
