Dear forest Pathers, We are presently working on Verticillium albo-atrum phylogenetics here at Penn State and are hoping to include as many isolates as possible from as many hosts as possbile. 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.
