Investigations on biological control of Heterobasidion annosum in Norway spruce with antagonistic fungi. II. Interaction experiments in wood. Seventeen fungal species were examined for antagonism against H. annosum in wood. After inoculation of stem sections and stumps by conidia and dowels, the distribution patterns of the mycelia within the wood were recorded. In spruce-wood antagonism was shown only by Hypholoma capnoides, Bjcrkandera adusta, Resinicium bicolor and Trichoderma spp. near the site of inoculation. As the distance from this site increased H. annosum became more dominant. Inoculations by dowels yielded more infections than inoculations by spores. The patterns of myeelial distribution within the wood were similar in stem sections and in stumps. Spruce stumps were colonized naturally mainly by Resinicium bicolor, Armillaria mellea s. I. and Nectria fuckeliana. In stem sections of Pinus sylvestris, however, Phlebiopsis gigantea displaced H. annosum effectively.read more

TL;DR: Trichoderma atroviride (T-15603.1) was consistently and highly competitive against most wood decay fungi with the exception of Polyporus squamosus which showed resistance towards antagonism in laboratory tests.

Seasonal patterns of spore deposition of heterobasidion species in four forests of the Western alps.
TL;DR: Although spores were captured from February to October at most sites, inoculum concentration consistently peaked in the late summer or early fall, suggesting different patterns of sporulation among Heterobasidion species.

Effectiveness of some biocontrol and chemical treatments against Heterobasidion annosum on Norway spruce stumps
TL;DR: The biocontrol agents Trichoderma harzianum, Verticillium bulbillosum, Hypholoma fasciculare, Phanerochaete velutina, Vuilleminiia comedens together with the chemical treatments propiconazole and the culture filtrate of V. bulbsum reduced H. annosum infections.

Population structure and responses to disturbance of the basidiomycete Resinicium bicolor.
TL;DR: Resinicium bicolor responded to both enrichment and destructive disturbances by the formation of an extensive cord system which enabled it to colonise discontinuously distributed resources and to overgrow fungi adjacent to it in a single resource unit, including Heterobasidion annosum.

Community of Aphyllophorales and Root Rot in Stumps of Picea abies on Clear-felled Forest Sites in Lithuania
TL;DR: The abundance of nearly all Aphyllophorales correlated positively with the stump diameter, and on larger stumps, fruit-bodies of several different fungi were more common, and the incidence of root rot correlated neither with the age nor with the density of the felled stand, but it correlated negatively with the proportion of deciduous trees within a stand.

Hyperparasitization of vesicular-arbuscular mycorrhizal fungi.

TL;DR: Spores of vesicular-arbuscular mycorrhizal (VAM) fungi often contain hyperparasitized spores even and 56.8 and 91.2% parasitized by H. fuscoatra, respectively, which may explain some erratic results which occur in chytrid described by Schenck and Nicolson (14).
