On Juniperus scopulorum in southern Utah, USA, R.G. Krebill found a black stroma (sclerotium) extending from in the soil to well up into the branches and small twigs giving the bark a fire-charred appearance. It is several centimeters long and up to 2 cm thick (mostly less). It’s composed of much-branched chains of cells, each cell about 10 mm long, 8 mm wide near the tips of chains but gradually increasing to 12 mm wide (measured cross-chain) back from the tips. The terminal cell is up to 16 mm long, presumably just before dividing. The brown (by transmitted light) cytoplasm shows no clear contents, the walls are darker brown.
This seems to fit Helicobasidium/Rhizoctonia in general but I don’t find reference to big, black sclerotia like this on conifers. Helicobasidium/Rhizoctonia is blamed for rot in pines, I think basal on the trunk (& root?). R. crocorum, which goes under several names, is possible, but the sclerotium doesn’t seem right.
I can mail a specimen if someone knowledgeable would look at it.

Biosecurity in a Global Context
The IUFRO International Biosecurity Conference 2009 will showcase advances
in forest biosecurity research from around the world. Speakers will cover
the range of issues associated with the exclusion, eradication or effective
management of pests to protect the diverse benefits offered by forests.
Invited speakers from around the world include:
· Dr Mike Wingfield – FABI, South Africa
· Dr Mark Lonsdale – CSIRO, Australia
· Dr Hugh Evans – Forest Research, UK
· Mr Peter Thomson – Ministry of Agriculture and Forestry, NZ
· Dr Alain Roques – INRA, France
· Dr Eckehard Brockerhoff – Scion, NZ
· Dr Andrew Liebhold – USDA Forest Service, USA
· Dr Enrico Bonello – Ohio State University, USA
This Conference provides a forum for forest entomologists, pathologists and
vegetation management scientists, forest managers and policy makers to
share knowledge, create networks and promote international actions.
Join us in exploring key questions such as:
· How do we model the impacts of weeds, insects and diseases on forest
productivity?
· How do we define pests of the future and model the likelihood of
their establishment?
· How do we stop pests moving around the world?
· Can we manage vegetation without herbicides?
· Can we manage quarantine pests without fumigants like methyl bromide?
· Are diverse forests more resistant to pest impacts?
· What are the best techniques for eradicating pests?
The conference incorporates:
· 6th International Forest Vegetation Management Conference.
· Workshop on managing the biosecurity threats to forests in a changing
global environment.
· Working parties of IUFRO division 1 (silviculture), division 7
(forest health) and division 8 (environment).
Post conference tour:
Delegates who wish to make the most of their trip have the option of
attending a week's tour of New Zealand's beautiful South Island.

Dear colleagues,
I am sending this note regarding the
California Forest Pest Council (CFPC), to
1) update contact and interest information of current members,
2) give an opportunity to anyone wanting to be on its mailing list
3) to see if others would like to become members of the Council and its
Committees.
The CFPC is an organization whose aim is to foster education
concerning forest pests and forest health, and advise the
California Board of Forestry and Fire Protection
on forest health protection. See http://caforestpestcouncil.org/
The major Forest Health protection issues covered
include established and emerging
insects, pathogens, abiotic factors,
invasive weeds, and animal problems.
The CFPC publishes an annual
California Forest Pest Conditions Report,
which is a great outlet for noting changes
in severity and occurrences of forest health problems.
CFPC has annual meetings every fall (this year, Nov. 18-19)
open to anyone interested in forest health, including
CFPC members, forest managers, forest pest specialists,
policy makers and analysts, and government agencies.
It also has summer field tours showcasing
California forest problems caused by
1) weeds, and 2) insects and diseases.
All are welcome to receive alerts of upcoming events,
or to join the council and its committees
and membership is free!
Please use the attached EXCEL form to update
contact info or show interest in being a member of
CFPC and / or one or more committees.
