Hypholoma fasciculare, woody debris and root disease cause by Armillaria ostoyae
Hypholoma fasciculare (Huds. Ex Fr.)
Kummer is confirmed in its ability to overrun Armillaria ostoyae (Romagn.)
Herink in culture. H. fasciculare displaces A. ostoyae from discs
of tree root where A. ostoyae is well established, and prevents A. ostoyaeI
from occupying root segments when both fungi are introduced simultaneously.
A simple method for inoculating H. fasciculare into stumps is described
and data supporting successful field inoculations are presented.
The ability of H. fasciculare to invade freshly killed stumps, even those
occupied by Armillaria, is demonstrated and it is speculated that the ability
of this saprophyte to invade fresh stumps is dependent upon inoculation
potential of the saprophyte. Bole removal from timber harvesting,
as opposed to natural disturbances which return boles to the soil, alters
the populataions and inoculum potential of saprophytes that can compete
with Armillaria ostoyae. Forest management practices that maintain
vigorous saprophyte communities in the forest floor and soil, may have
potential for combating Armillaria root disease.
