Identifying the Injury. - The fungus develops primarily in the roots and butt and seldom extends more than 15 or 20 feet up into the stem. The initial stage of decay appears as a light yellow stain. In the advanced stage, the heartwood becomes brittle and breaks into large yellow-brown to reddish-brown cubes. Biology.

    Armillaria root disease and butt rot, caused by several species in the fungal genus Armillaria, is common on stressed and weakened known as shoestring root rot, the pathogen colonizes roots and the root collar of aspen, especially stressed or over-mature trees resulting in butt decay, losses in wood volume and quality, and tree mortality. Infected trees often have branch dieback and fewer than normal leaves that are yellowed. Although the root rot begins well out on the root system, the fungus eventually reaches the butt of the tree where it forms large, tough, irregularly shaped, light- to dark-brown shelves at or just above the soil line.

Many fungi are capable of causing root rots and some cause considerable decay of the butts of trees as well. Root rots are more common on older trees or trees which have sustained root or basal injury.

Root rots thrive on poor soil conditions. The fungal pathogen Kretzschmaria deusta is sometimes known as the burnt crust fungus or brittle cinder fungus. Hosts. Root and butt rot from Kretzschmaria is most common on European beech (Fagus sylvatica) in landscape settings in the fungus can also be found on American beech (F.

They involve the roots and in many cases the butt also. A tree's "butt" is above the roots but separated from the trunk which continues upward toward the terminal bud A tree's butt is often referred to by loggers as the bottom log of a felled tree. The first cut nearly always starts at the butt or base of the tree for the initial cut.

The aim of our Working Party is to promote international co-operation between forest pathologists working primarily with root and stem rots of forest trees. Meetings of the Working Party are organised at intervals of 3 to 5 years. The numbers of participants in these meetings range from 40 – Root and butt rots are often implicated as causal factors influencing windfall and mortality of residual trees following partial cutting.

Measurements of decay at stump level (i.e., the upward extension of root rot) were made on cross-sectional discs taken from windfallen and standing dead to year-old black spruce (Picea mariana (Mill.)BSP) near Nipigon in northwestern by: Root and butt rots, instead, are exclusively caused by fungi belonging to the homo- basidiomycetes.

The three genera Armillaria, Hetero- basidion,andPhellinus have broad worldwide distribution and probably are responsible for the majority of root diseases in temperate forests.

Armillaria root rots. Armillaria causes root disease of woody plants (including forest trees, amenity trees, orchard trees and vines). This chapter summarizes the knowledge of the fungus in forestry and emphasizes interesting facts for the forest manager.
