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.

To date, much has been accomplished, but what are the current research
needs?
We need your input through an online survey tool ? these very short
surveys will take just a few minutes of your time.

Dear colleagues,
Many thanks to those who responded to my request regarding
Mycosphaerella dearnessii (Lecanosticta acicola) that I sent at the end
of February. 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(a)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(a)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%2…
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!
With best regards,
Thomas Kirisits

Plan now for the next Western Hazard Tree Workshop, to be held in Medford,
Oregon, during the week of June 14, 2010! 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,

contest will also be featured.
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.
Please check the workshop website for details:

Greetings! 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(a)ncsu.edu
Thanks!

I received this from a colleague and wondered if anyone had an answer to
his question:
Dear Professor Schmitz,
I am writing at the suggestion of Mary Warner, associate dean of the
medical school. Mary and I have been working jointly on a diagnostic
medical case project.
For many years I have owned a farm on the east bank of the Hudson River
just south of the Rip Winkle Bridge. On the steep bank that descends
from the farm house to the New York Central railroad tracks, there is a
small forest of sumac trees, interspersed with other growth. The sumac
trees generally grow straight up, at a rate of 6 to 10 feet per year,
with one exception. The exception comes out of the ground and grows in
circles. See photo 001, attached. If you will look to the left of the
chain saw, you will see a twisted length of copper about three-quarter
inches wide. The copper is embedded in the root system of the crooked
tree, and cannot be removed by vigorous tugging.
When Mary and I looked at these photos last week in her office, we
speculated that the DNA of the crooked tree may have mutated and is
sending atypical signals to the trees cells. We talked briefly about
Wilson's disease in humans, which is due to an excess of copper in the
bloodstream. Needless to say, neither of us knows anything about
crooked sumac trees.
Our current schedule calls for me to return to New Haven at 11 a.m. on
Wednesday March 10th. If you expect to be on campus that day, I could
bring you a length of the crooked tree. I plan to stay over at the
Graduate Club that night, and will therefore be available on March 11th
as well. Alternatively, you might like to visit the farm, which is
about 2 1/2 hours from Harkness Tower. I would love to have your views
on what is causing the crooked tree to grow in circles. Please feel
free to discuss this subject with your students.
If you search Google Earth for 194 Greendale Road, Hudson, NY, 12534,
you will access an aerial view of the farm. The crooked tree is on the
bank to the east of the farmhouse/barn at the north end of the farm. To
the west of the farm house there is a pinot noir vineyard, while the
grapes to the South are largely Chardonnay.
I look forward to hearing from you. With best regards,
Peter Brengel, Class of 1953

NSF/CAFS PhD Assistantship: Endophytes for improved growth and disease
resistance of forest trees.
There have now been many demonstrations of the effects of endophytes on
plants that range from positive (i.e., mutualism) to negative (i.e.,
parasitism). This project addresses research areas of site resource
utilization with select endophytes and growth, yield and quality of
forest plantations.
Of fundamental interest is the opportunity to research endophyte
community assembly rules under ecologically realistic conditions in a
range of host plants including species of Populus and Pinus.
