Book Description
Many rust fungi (Uredinales) that infect rhododendrons are difficult to identify because of similar spore size & overall morphology. This study examined herbarium specimens of Asian rhododendron rusts by light microscopy & scanning electron microscopy as part of a morphological study of rusts in the genus Chrysomyxa. The specimens were compared with similar taxa from Europe & North America. Revised & illustrated descriptions are provided for the uredinia & telia of Chrysomyxa dietelii and C. succinea; details of the conspicuous uredinial peridium of both species are described for the first time. A new genus & species is proposed to accommodate a rust fungus with uredinia covered by a peridium of ornamented cells and teliospores enclosed in transparent outer sheaths. Three new anamorphic species with unique urediniospore morphology are also described. A key to Asian rhododendron rusts that form uredinia is also provided.

Book Description
Western Oregon is home to native Rhododendron species and is the center for cultivated Rhododendron production in the United States. These Rhododendron spp. are known to be infected with fungal endophytes. However, the community structure of these endophytes in native and cultivated Rhododendron is poorly understood. Our study targeted the foliar fungal endophyte communities of two native Rhododendron spp. and two non-native commercially cultivated Rhododendron varieties. Parallel culturedependent (fungal isolation and identification based on ITS sequencing) and cultureindependent sequencing approaches (metagenomic sequencing of the ITS region using 454 pyrosequencing) were employed, and results provided evidence of distinctly different community structure in each host species. Additionally, results indicated higher diversity among cultivated and nursery grown Rhododendron. This suggests that the close proximity of the nurseries sampled to the forest environment allows exposure to two distinct sources of endophyte infection. Together, our results show the importance of host identity and environment in structuring the associated endophyte communities.

Book Description
This substantially updated edition now in full colour provides key techniques used when working with fungal and fungal-like plant pathogens. As a practical manual it also deals with disease recognition, detection and identification of fungi, plus methods to characterise and curate fungi and handle them under quarantine and quality assurance systems. Fungal Plant Pathogens: Applied Techniques, 2nd edition provides a valuable guide to investigating fungal plant diseases and interpreting laboratory findings for postgraduate and advanced undergraduate students, extension plant pathologists, consultants and advisers in agriculture, forestry and horticulture, and the food supply chain.

Book Description
Diseases of Trees and Shrubs is a comprehensive pictorial survey of the diseases of, as well as the environmental damage to, forest and shade trees and woody ornamental plants in the United States and Canada. An authoritative reference, it is also a reliable and handy diagnostic tool that will simplify the identification of specific plant diseases by focusing on signs and symptoms that can be seen with the unaided eye or with a hand lens. This long-needed book gives readers complete, up-to-date information in an easily understood and convenient way. Each of the 247 color plates faces a page of explanatory text covering the biology and ecology (including host and geographic ranges) of the disease-causing agents (pathogens), a list of key references (there are more than 2,250), and, in some cases, black-and-white illustrations of pathogens. Selected information about biological and cultural control is provided. Scientific terms other than Latin names of pathogens are used only when necessary, and a glossary of terms and a comprehensive index are included. The color plates contain more than 1,700 illustrations of the diseases and injuries that some 350 biological agents and environmental factors cause to more than 250 species of plants. The book also serves as a guide to hundreds of other diseases related to those shown. The authors have used three levels of organization for this book. At the first level, diseases caused by biological agents are separated from those caused by environmental stimuli. At the second level, most diseases are grouped according to the plant part affected: leaves, twigs, limbs, roots, trunks, or the entire plant. At the third level, diseases are presented according to the taxonomic relationships among the pathogens. For this major project, the authors examined and photographed diseases and environmental damage in the field, visiting more than 50 states and Canadian provinces. Their book reflects the most important developments in fungal biology and taxonomy, plant bacteriology, virology, and environmentally induced stress in plants. It summarizes information about newly discovered diseases and provides up-to-date accounts of olds ones. Diseases of Trees and Shrubs can be profitable reading for anyone whose technical training does not extend beyond general biology, yet will also be informative to advanced students and plant pathologists. It will be welcomed by agricultural and horticultural advisers, plant inspectors, arborists, nursery professionals, landscapers, foresters, and urban planners. Wayne A. Sinclair is a Professor of Plant Pathology, Howard H. Lyon is Biological Photographer (retired), Department of Plant Pathology, and Warren T. Johnson is Professor of Entomology, all at Cornell University.
