Recently I was contacted by Dr. Chuck Hodges, retired US Forest Service Pathologist, regarding his revision of the Forest Diseases Nursery Diseases in the United States chapter on Cercospora Blight of Junipers. Dr. Hodges is looking for updates on distribution and hosts of Passalora sequoiae (formerly Cercospora sequoiae). The original chapter lists distribution as "most of the southern United States and as far north as Pennsylvania". If you have any reports of this pathogen outside this general area, please forward to Dr. Hodges at: charles_hodges at ncsu.edu Thanks! /s/ Borys Tkacz <><><><><><><><><><><><><><><><><><><><><><><> Borys M.

The meeting site will be at the USDA Forest Service's J. Herbert Stone Nursery in Central Point. Lodging is available in a variety of hotels in Medford. As with the previous five workshops, the intended audience includes pest specialists, arboriculturists and other professionals who have responsibilities for providing training and guidance in hazard tree management, particularly in forested settings. There will be one and a half days of indoor discussions and presentations and one and a half days in the field. Indoor topics include: Roadside Danger Tree Policies and Assessment; Biology and Taxonomy of Wood Decay Fungi; Oak Defects, Decays and Failures; Options For Not Removing Hazard Trees; Effects of Pruning on Douglas-fir; Illusions and Consequences in Tree-Risk Assessment- When Law and Arboriculture Collide; Powerlines, Wildfires and Tree Failures: School Fire Case Study; and Decay From Phellinus pini: Case Studies and Lessons Learned.

The field portion of the workshop will include visits to sites in the southern Oregon Cascades on the Rogue River-Siskiyou and Winema National Forests, with one stop in the Rogue Valley at the J. Herbert Stone Nursery. We'll see and discuss a number of hazard tree situations and topics including: decline and failure in native oaks, indicators used in the USDA Forest Service Region 6 roadside danger tree program, the danger of laminated root rot in a recreation site, concerns with decline in specimen legacy trees, and hazard potential in heavily-used developed sites in older true fir stands.

Marion Kessler and Josef Janusek will contact you soon and provide you with detailled sampling instructions. I thought I send out our request again (see below). Maybe other colleagues are willing to assist in collecting samples? Thanks you very much for your efforts! With best regards, Thomas Kirisits ___________________________ Dear colleagues, On behalf of two Ph.D. students I would like to ask you for assistance of their Ph.D. projects! For molecular / population studies on Mycosphaerella dearnessii (anamorph Lecanosticta acicola), the causal agent of brown spot needle blight of pine species (Pinus spp.), we would be interested to obtain isolates / populations of isolates of this fungus and/or pine needles infected by M. dearnessii (preferably with conidiomata and/or ascomata pesent). In the latter case the isolations would be done by the Ph.D. candidates themselves. The work will be done as part of the Ph.D. theses of Marion Kessler (marion.kessler at bfw.gv.at ) at the Institute of Forest Entomology, Forest Pathology and Forest Protection (IFFF), University of Natural Resources and Applied Life Sciences, Vienna (BOKU), Austria (advisors: Erhard Halmschlager, Thomas Cech & Christian Stauffer) and Josef Janousek (janousek.jose at gmail.com) at the Faculty of Forestry and Wood Technology, Mendel University in Brno, Czech Republic (advisors: Libor Jankovsky & Christian Stauffer). Isolates and samples from all parts of the world would be very welcome! Of particular high interest are isolates from North, Central and South America. This is because the fungus is suspected to be native there and for comparisons of putative native versus introduced fungal populations American isolates would be essential. Brown spot is a common and important disease of Pinus palustris and other Pinus spp. in the south-east and central USA, so we hope that US colleagues will be willing to help in providing isolates/samples. But isolates/samples from other parts of the world, especially also from Asia, would be also very valuable. So far Marion and Josef have a good collection of isolates from several parts of Europe, but additional European material would also be good and can only strengthen the planned work. The EPPO diagnostic protocol for Mycosphaerella dearnessii contains a lot of useful information on diagnosing the disease and it also includes a number of excellent photographs of the symptoms: http://www.eppo.org/QUARANTINE/fungi/Mycosphaerella_dearnessii/pm7-46%281%29%20SCIRAC%20web.pdf In addition, Josef Janusek prepared a page with a few photos of symptoms of brown spot needle blight: http://picasaweb.google.cz/pepino96/BrownSpotNeedleBlightOfPines# If you are able and willing to help, please contact me. Marion Kessler and Josef Janusek will then provide you with further information (details for sampling, sending, import permit, etc.). Please do not hesitate to contact me in the case you have any further questions. Thank you very much in advance for your help! Your assistance will be invaluable and very much appreciated!

We have purchased many isolates from type culture collections but as I'm sure you are well aware, these collections are not only prohibitively expensive but also limited in host diversity and geographic location. We are hoping that some of you may have Verticillium albo-atrum within your own collections. We would appreciate it if you could send us subcultures as well as any pertinent information regarding host, location, year of isolation, etc.We presently have all necessary APHIS permits to receive isolates from within the U.S. as well as from all other continents. Please contact me directly for a pdf copy of the permit if you are interested in contributing to this project. I look forward to your responses. Regards, Matt Kasson p.s. If you know of anyone else that might possibly be interested in contributing isolates for this project please forward this email on. Matthew T.
