Responses regarding the orange-stained white pine query I posted last week.
Thank you to all who responded!
Most of the people who weighed in felt that this could be "red heart," or "red ring rot," caused by early stages of infection by Porodaedalea (Phellinus, Fomes) pini.
A few others suggest that the coloration is not necessarily caused by an infectious agent, but is rather just something peculiar to white pines, or perhaps associated with wet sites, slow growth, or suppression.
I will try to culture out of some of the colored wood, onto media selective for Hymenomycetes (thank you to Nick Brazee for media recipes).
All the responses follow.
~~~~~~~~~~~~~~~~
Hi Bob, how about something simple like red heart caused by Phellinus pini? - Kevin T. Smith, Ph.D., USDA Forest Service
~~~~~~~~~~~~~~~~
Hi Bob: Just saw your FORPATH posting on the white pine problem.
From the looks of it, I think it could be the start of red ring rot caused by Phellinus pini (Fomes pini). The early stage of discoloration varies a bit from reddish to pinkish before the wood is severely decayed (real soft). The fruiting bodies of the fungus come out below old branch stubs....you might also see some pitch flows from branch stubs ...an early symptom of the disease. The fungus attacks many conifer species but in our area older growth white pines are commonly diseased....the cross section of the stem you provided appears to be quite old and slow growing due to no thinning in the
past....also, a stress on the trees and to the advantage of P. pini.
That would be my best guess without seeing the trees and poking around a bit. Hope this helps...let me know what others think. Hope all is well. Have a good day and greet those I know. - Dale R. Bergdahl
~~~~~~~~~~~~~~~~~~
The color, and the pattern in the lower picture, are the same as red ring rot caused by Phellinus pini (or whatever the correct name is at the moment). I don't see any of the white pocket rot you usually get with more advanced infection. Although this fungus is famous for infecting through branch stubs, it is happy to take advantage of wounds, as in the small cookie. - Barbara Burns, Vermont Department of Forests, Parks, & Recreation.
~~~~~~~~~~~~~~~~~~
I have seen the orange wood in a local woodlot, and foresters refer to it as "pumpkin wood". There is no apparent relation to infectious disease or tree health. The coloration just seems to be peculiar to white pine in certain stands and locations. - Bill Livingston
~~~~~~~~~~~~~~~~~~
If this is from a butt disk the most likely explanation is the tree is infected with Tomentosus root disease (TRD) caused by Inonotus tomentosus. This is a very characteristic stain pattern, associated with this root disease, which is expressed, up the stem from the roots, well in advance of any signs of fungal degradation. In the advanced stages of decay this fungus causes a very distinct type of pocket rot (see stump image). This a serious root disease most often associated with Picea spp causing stand opening disease, but also affecting other conifer spp. Pinus, Abies, Larix, Thuja, Tsuga. Where I. tomentosus infects the root system this can easily explain the dieback and decline in the stand. Most infection takes place underground through root grafting between infected and healthy roots. Roots systems of stressed trees are susceptible to infection as they cannot wall off the fungus penetration from an infected adjacent root, often resulting in disease/mortality centres and eventual stand openings. Visible signs (fruiting bodies) of the disease are evident only in the late fall, on the ground sprouting along infected roots and sometimes present at the root collar of severely infect trees (see fruiting body images). Some of these fruiting bodies may still be evident in the stand now, but will deteriorate relatively quickly once the weather warms up as this is an annual leather type fruiting body. - Gary Warren, PhD , Canadian Forest Service
~~~~~~~~~~~~~~~~~~
In Boyce, reads : The heartwood of sugar, western white, and eastern white pines often becomes a pink, light-red or vinousred color on dying. Have you observed the presence of the fungus Porodaedalea pini (Fomes pini) that cause Red ring rot? - Guy Bussières
~~~~~~~~~~~~~~~~~~
I asked a recent PhD grad who did a lot of research on EWP (Dr. Philip Marshall). Here is what he said: "Yes I have seen this a number of times, especially in trees from wetland sites. It seems to be associated with suppression/stagnation/slow growth, and the color is from an accumulation of resins in the wood (so there may be a stress response involved). " - Ann Camp
~~~~~~~~~~~~~~~~~~
It is hard to tell for sure using photos but what caught my eye was the beginnings of a ring pattern just inside the sapwood region and that is quite common....with ref ring rot. Anyway, good to hear about the other comments and that Kevin agrees with me...I guess.... Wasn't aware of the name change again...that makes 3 scientific names during my career. Looking forward to hearing more comments...once you get them all maybe provide a brief summary and send to FORPATH. Hope all is well. - Dale R Bergdahl
~~~~~~~~~~~~~~~~~~
Below is my explanation for "pumpkin pine" sent to Karen Bennett, Extension Forestry Professor and Specialist, University of New Hampshire, Durham, 9 April 2012, in response to her question about its cause.
A whole range of colors occur in columns of wound-initiated discoloration during the early pre-symptomatic stage of decay in white pine. For example, early stages of decay by Phellinus pini is often called "red heart". The color that is caused by oxidation of phenolic extractives of heartwood and can vary with pH. Pioneer bacterial associates of decay fungi can make wood more basic if the oxygen content of wood is low because they feed on proteins and produce ammonia, and more acidic at high oxygen content because they feed on carbohydrates. Pioneer fungi associated with early wood decay can grow as budding spores and may produce pigments of their own depending on pH and trace metal content. Once the oxygen content increases near the open wound as exposed wood dries, the decay fungi begin to actively decompose wood to produce typical symptoms of decay such as the white pocket rot of P. pini and then spread through the discolored wood over time from years to decades. The size and shape of the discoloration stage proceeding symptomatic decay varies with the number and size of woods exposing wood to infection. The loss of branches leaves a stub wound that exposes the central portion of the tree to aeration and infection; the loss of bark yields a scar wound that exposes sapwood and live inner bark to dehydration, aeration and infection. Color variations depend on complex interactions of phenolic compounds produced by the tree, the degree of dehydration and aeration, the types of pioneer bacteria and fungi associated with the decay pathogen which colonizes the exposed live, dying, and dead wood. Some decay pathogens like P. pini attack and kill live outer sapwood and inner bark causing a canker that continues to expose live tissue, other pathogens can attack only sapwood, but not inner bark, and yet other non-pathogenic fungi attack only dead heartwood. The living sapwood and inner bark is protected to varying degrees by compartmentalization, the protective system in tree which varies genetically and with environmental conditions. Trees with poor compartmentalization have larger columns than those with strong compartmentalization. The light brown pine boards with unusual yellowish-golden or reddish brown hues known in the trade as "pumpkin pine" is likely found only in larger, older trees because it takes time for large columns to develop in the heart of trees likely exposed by smaller stub wounds keeping the oxygen content relatively low so decay will not spread quickly through the discolored wood. The same colors can be seen in association with lots of smaller columns in smaller, younger trees, and occur as isolated patches in boards cut from them. It is easy to imagine red heart altered to the colors of pumpkin pine by adjusting the pH and perhaps the trace metal content during the early stage of decay when pioneer bacteria and fungi are active before advanced decay begins. So there is my explanation of pumpkin pine. - Walter Shortle

Hello Forpathers,
The following pictures were taken from recently felled white pines in a small area on water company property experiencing some severe dieback. This is a very dense stand, heavily overcrowded and large, maybe 60-80 years old, having obviously never had a thinning. So they're stressed. But when I had one of the foresters fell a couple of trees so we could look for any signs of disease, we noticed this bright orange staining. I don't have any reason to believe that this orange staining is the cause of the dieback, since it's not common to all the trees that are dying, but it's a curiosity worth inquiring about. The orange color was most strikingly vivid when the trees were first cut.
Thanks,
Bob

Greetings Forpathers-
We are about to embark on a very large project that will entail coring a large number (a couple thousand) tropical rainforest trees to look at fungi decaying the insides of the trees. The trees are part of a long-term study, and there is significant (and reasonable) concern that we do no harm to the trees that might speed their demise. As such, there are very strong opinions about what we should do to the holes after we remove the cores. As the pathologist on the project, it is my responsibility to provide a clear, evidence-based rationale for what we do, and I'm seeking Forpath advice on the latest (preferably with published studies).
I know there is plenty out there about not tarring or painting pruning wounds. I have a rather old publication on wound healing of cores in tropical trees that showed pretty rapid sealing of drill wounds (through a variety of mechanisms) (Gilbert and Guariguata 1996 Biotropica 28: 23-29). But I'm not finding much empirical work out there on what should best be done to handle deep wounds like trunk cores on trees.
Any advice -- your personal observations, citations, rationale for different approaches - would be greatly appreciated.
What would you do to protect trees from infection after coring?
Thanks very much,
Greg

Dear colleagues,
With deep sorrow and regret, we have to announce that Professor Edwin
Donaubauer passed away on March 18, 2012 in his 80th year of life in
Vienna.
The burial took place on March 27 at Mauer Cemetery. A requiem will be
held at parish church St. Erhard, 1230 Vienna, Endresstrasse/Maurer
Hauptplatz, on Saturday, April 14 at 09:00.
Edwin Donaubauer was a pioneer of forest pathology, forest entomology
and forest protection in Austria. For 40 years he was one of the
influential persons of the Federal Forest Research Centre, Vienna (now
Federal Research and Training Centre for Forests, Natural Hazards and
Landscape – BFW, http://bfw.ac.at) and greatly contributed to its rise
to an international recognized institution for forest research, first as
a young scientist and from 1964 to 1994 as head of the Institute of
Forest Protection (http://bfw.ac.at/rz/bfwcms.web?dok=1244). Edwin
Donaubauer was also closely attached to the University of Natural
Resources and Life Sciences, Vienna (BOKU, http://www.boku.ac.at/,
http://www.wabo.boku.ac.at/507.html), where he has been lecturing for 40
years, from 1971 to 2011.
Besides his national commitments in Austria, Edwin Donaubauer was
thinking in international dimensions, was in intensive contact with
numerous colleagues abroad and was strongly engaged in international
forest research activities (e. g. IUFRO and FAO). He was one of the
founders of the European Journal of Forest Pathology (now Forest
Pathology) and has been serving as a member of its editorial board for
38 years.
In a world of specialization Edwin Donaubauer always impressed us
because of his deep and broad knowledge in all sub-disciplines of forest
protection (forest pathology, forest protection, air pollution and
wildlife ecology). He will be remembered for his open and communicative
personality, his positive attitude to life, his good sense of humor and
his readiness to help others.
Edwin Donaubauer was so enthusiastically committed to teaching that he
continued to give lectures and courses into his late 70's, even until
November 2011. Generations of students will remember his enthusiasm for
science, his inspiration as a teacher and his unique way of lecturing
combining well-grounded expert and practical knowledge with humorously
and colorful told anecdotes and case studies.
Attached you will find a photograph of Edwin, how we will remember him
(taken during an excursion to the Alps in 1991).
He was a devoted husband, father, grandfather and mentor to many. He is
survived by his wife Annelies, his daughters Andrea and Beatrix and his
son Christian and their families.
We strongly miss our passionate friend and insightful mentor!
Warm regards,
Erhard Halmschlager & Thomas Kirisits (BOKU), Thomas L. Cech &
Christian Tomiczek (BFW)
