Heterobasidion occidentale is a tree root-rotting pathogenic fungus in the family is endemic in western North America west of the Rocky Mountains from Alaska to southern Mexico. While a natural agent of forest turnover, H. occidentale has become of increased concern due to forest management processes such as pre-commercial thinning, altered site density and species Family: Bondarzewiaceae. Based on experiences on experimental exotic plantations, the introduction of such exotic species such as cedar (Cedrus atlantica), Douglas fir (Pseudotsuga menziesii) and white pine (Pinus strobus) could provide the most success under the Hungarian ecological conditions. Cedar and white pine are considered as alternative tree species for stands and plantations occupied by Pinus sylvestris and Author: J. Gergácz. The Polyporaceae of North America.-IIl. The Genus Fomes BY WILLIANM ALPHONSO MURRILL The generic name Fones is usually accredited to Fries, but this author never employed it to designate a genus. In Novae SyII1-bolae, 46, I85I, the genus Polyporus is subdivided into Eupoly-porus and Fomiies, the latter division being described as follows. The fungus, Fomes annosus, usually enters by infecting freshly cut stump surfaces. That makes annosus root rot a problem in thinned pine plantations. The fungus produces conks that form at the root collar on roots of living or dead trees and on stumps or on slash.

Annosus Root and Butt Rot. Annosus Root and Butt Rot is a disease spread by the fungus, Fomes annosus. It is primarily spread when tree stands are thinned. The fungus enters through the cut tree stumps and then spreads underground to healthy living tree roots nearby. Conks found at the base of the tree characterize this : Charlotte Gerber.

Fomes annosus is reported on white fir in Colorado for the first time. The pathogen is common in many stands in the southern portion of the State where white fir is a major component of the forest type. Infection centers often contain older dead trees which serve as inoculum sources for root infection of younger recently killed trees.

Fomes annosus was located within white fir stands on three southern Colorado national forests (Fig. 1 and Table 1). The fungus was most prevalent in southern portions of these forests where white fir was common.

Fomes annosus was often associated with trees with green foliage and little cambial necrosis. In such cases the only evidence of.

The increase of wood decay due to the fungal pathogen Heterobasidion annosum is expected to increase the vulnerability of tree stands to wind damage due to the decrease in tree anchorage (by wood decay in roots) and stem strength (by wood decay in stem wood).
