Book Description
Random sampling on 15 National Forests in the Northern Rocky Mountains revealed that Armillaria spp. were absent from cold-dry and hot-dry habitat types and were nearly always present in the cool-moist to warm moist habitat types.

Book Description
Excerpt from Armillaria in the Northern Rockies: Delineation of Isolates Into Clones Knowledge about distribution and behavior of Armil laria spp. In several regions has appeared in recent years. Two reports published in 1978 outlined the concept of intersterility groups and mapping of the geographic extent of clones. One dealt with the genus in the northeastern portion of North America (ullrich and Anderson 197 8) and the other with Armillaria in Finland (korhonen 197 The above authors outlined necessary technology to map the extent of both vegetative and sexually active clones. Isolates will fail to join together because they belong to different intersterility groups or they are different genotypes within the same group.

Book Description
Excerpt from Occurrence of Armillaria Spp. In Forests of the Northern Rocky Mountains Many studies have reported that in terms of geographic distribution and host range, Armillaria spp. Are ubiqui tous (ehrlich 1939; Hobbs and Partridge 1979; Hubert 1950; Swift The primary objective of such studies has been to determine the degree of its damage rather than the distribution of the fungus. Typical examples are Carey and others Williams and Marsden and James and others wherein sample points were selected by location of symptomatic trees or root disease centers. What do we need to know about Armillaria? How ex tensive is the distribution of various species of Armillaria and to what extent are these species pathogenic or sapro phytic? Useful information could also include host, patho genic or saprophytic condition, and taxonomic affiliation of each fungal sample. Knowing probability of occurrence (such as a proportion of -ha plots) of pathogenic and nonpathogenic entities in relation to other ecological criteria could serve as the basis for classifying forest lands according to risk of specific host species, given various management actions. Control measures could be similarly categorized. In 1983, we began a study of population level genetic and ecological interactions between Armillaria and its conifer and hardwood hosts. The two primary objectives of this research were (1) to predict Armillaria risk by habi tat type, host species, and stand management history; and (2) to develop ways for assessing genetic and physiologic responses between host and fungus populations in North ern Rocky Mountain forests. This paper reports on the oc currence of vegetative parts of Armillaria spp. By climax series. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
