    Bulge On Cherrybark Oak

    Sorry, but I'm not sure if I'm focusing on the right bit. The obvious swelling that begins about half-way up the stem is mostly easily explained by girdling. Sure, wire (barbed or otherwise) could do it. Polypropylene clothesline could too, etc.

    2nd opinion - fungus and risk assessment

    Thanks ATH for the update. Yes, this is what I was trying to get to with my posts above. Good they have the ID to genus. We sometimes act as if there was some platonic ideal of taxon characteristics, be they macro- or microscopic or molecular. Then we compare our sample unknown to those ideal...

    2nd opinion - fungus and risk assessment

    Sure looks like Kretzschmaria to me. Perhaps the re-test will show that, maybe not. Widening the scope, it certainly looks like mycelia from the Xylariaceae, a family in the ascomycetes. And jumping to superficially similar fungi like Dendrothele in the Corticiaceae (in a broad sense) is...

    Oak gall ID

    A scan of that 1940 guide by Felt is available for free download through a link into a library in India. Not a great high-quality scan, but still useful. Just search in Google Scholar on the title given by ATH in the post immediately above. I don't see it in

    Oak gall ID

    Sorry JD, I wasn't clear above. When I said that the ref "should be available as PDF" I meant that it "ought to be available but was not". Me bad! There were several hardcopy revisions. I'll see if I can get the most recent one from the national ag library and then put a copy in Treesearch, the...

    Oak gall ID

    That Forest Service guide mentioned by ATH is available in a simple hyperlink format (and a slightly shorter title) at: Yes, that should be available as a PDF. If I had a clean or otherwise paper copy, I'd scan it and get it out there!

    Maple Anthracnose?

    Several distinct species of fungi cause anthracnose on maple, which can account for some slight differences in symptoms and course of infection. The most damaging infections occur at leaf emergence. Consequently, the greatest benefit from chemical control is prior to or at leaf emergence...

    How do you recognize a node?

    Yes, thanks Daniel! I hope somebody finds this stuff useful. It's useful to me to be thinking about it as well! Kevin.

    Increment Bore Diameters

    ATH and Guy are right on the money here. The first thing that an arborist should know about increment boring is that rarely is it necessary! Now, I'm not necessarily agin' it! I've done a fair bit with the dendrochronology community that travel with borers as other people travel with toothbrushes!

    Hen of the woods right?

    Hi all, looks like a past-prime hen-of-the-woods aka maitake, Grifola frondosa. With this one, there aren't too many lookalikes. Famous last words, I know.

    Willow Oak decline and fungal disease?

    Also, that tan jelly-y guy might be Otidea rather than Auricularia. Interestingly, those are both described as "ear-shaped" although they are very different creatures with the former an asco and the latter a basidio-mycete. Makes no difference for treatment, I expect.

    Increment Bore Diameters

    All depends on what information you want to get from the core! The smaller the diameter, the easier to twist in...and maybe to twist out. So if the goal is to measure residual wall thickness, go with the narrow one. If you are fixin' to measure or crossdate tree rings, then I like the wider...

    Willow Oak decline and fungal disease?

    The little white brackets do seem to show some indents along the margin which tells me Schizophyllum, meaning that there is dead sapwood beneath and not just dead bark. The brownish jelly looks like Auricularia to me, also a sapwood-rotter. The little spots look like Tubakia, what I first...

    ISO books and advive

    Welcome to the Buzz! Shigo's material can be divided into two sets: (1) His research journal and feature articles written while a USDA Forest Service researcher, many of which are freely available and linked to Just search on "Shigo". Not all of his research...

    Learn your land

    Excellent mushroom video! My primary quibble is that the presenter considers that hemlock red varnish fungus (Ganoderma tsugae) is the medicinal reishi or ling-zhi mushroom as known in Japan and China, respectively. In the recent past, the North American Ganoderma lucidum (on hardwoods) has...
