Thanks TTF for the shoutout. As I recall, that session was over two days, one at Brooklyn Botanic Garden and one at Green-Wood Cemetery. I've done a few things for BBG, and I confuse easily.
For those curious, this education program offered as part of the BBG academic-credit horticulture...
I don't know of any research on the effects of an anti-gibberillin on tree wound response. I know I haven't done anything with that. I'll poke around a bit in the research/practitioner space.
Thanks Daniel for the question. To me, the quick answer is "Yes, to be sure".
The more scholarly answer requires some examination of science history and philosophy. The root word for "intelligence" conveys the sense of being capable of learning new stuff. Historically, human intelligence has...
Respectfully, I'm not sure what TreeVB means with respect to "completely trust CODIT". CODIT is a model for the concerted set of processes within the wood of living trees to resist the spread of the effects of injury and infection. Yep, some tree species invest a lot in compartmentalization...
Excellent question, Tom_Otto! I realize this is an ancient thread to which I may have already responded but perhaps for newcomers:
The case for removal of attached, dead branches is more inferred than directly proven by research. (1) A dead, attached branch precludes wound closure, leaving open...
Lovely! Old and fresh sulfur shelf. I learned it first as Laetiporous sulfureus. That name is based on European collections which is likely a different fungus. So that genus is in the process of revision which has resulted (or will soon result) in a new name for the North American sulfur shelf...
I try not to be too thin-skinned at pranksters, but I have been presented to ID local fungi....while the sample was freshly brought from Belize or South Africa. Same with tropical wood folks present as coming from the Carolinas or something. By nature, I'm pretty trusting and gullible...as a...
Thanks OOM, I think I see a small patch of gills beneath the cap. If I'm fooling myself and there no gills, I'm leaning much more towards Leotia *if* the cap and even the stipe were viscid (slightly slimy or "jelly-like". ID often involves much more than a single snapshot with few diagnostic...
I'd start with the ringless Armillaria, what I learned as Clitocybe tabescens. I cant' see how the gills are attached to the stipe. Is the cap waxy in feel, in which case I'd go with a Hygrophorous.
Or is it a trick question?
Thanks Reach for the plug. Mark, the critical key ID feature here in the presence or absence of little, downward spines (rather than pores) on the vaguely horizontal lower surface. If spines, I'd start with Irpex lacteus or the "milky-tooth". So who cares? Independent of a precise ID, you...
I know that when I was interviewing job candidates, I always requested a co-dependent enabler. If they laughed in my face, they had a chance. If they carefully noted and wrote that down...well, they'll probably have trouble although not with me.
In the spirit of following the flow of discovery, the reader may be interested in the Shigo and Larsen 1969 color photoguide here which was quite radical for its day and available for free here. Keep in mind it is a very large file and really needs to be downloaded rather than simply viewing in...
Stinky indeed! Yes, it is the common stinkhorn. Linnaeus had it right, we still use his original name of Phallus impudicus. The stink (chemicals including putrescine and cadaverine) attracts flies which help spread spores / mycelial fragments. @Serf Life did you take this picture and was it in...
The two books are quite distinct from each other, but follow the same arc.
I'd say, go with the order in which he wrote them. Modern Arboriculture won't be nearly as powerful if the reader hasn't gone through A New Tree Biology. Both books enrich my life daily through a greater understanding of...
All sorts of decay fungi could present themselves as in the photos, but when I see the images I think Stereum gausapatum or Stereum hirsutum, depending on whether the thallus "bleeds" when scratched (the former) or is hairy (the latter). In the good news / bad news department, whether it is one...
Sorry to be late to the party here. With the usual disclaimer that most folks who are paid to identify fungi do not do so from photographs, I'd go with Inonotus dryadeus, the weeping (or warted) polypore.Why? Several prominent and unrelated wood decay fungi start out from a nubbin (my term) or...
I'd start with Amanita thiersii or Chlorophyllum molybdites. These are quite different gilled mushrooms. The shaggy Amanita will have a swollen, saccate base and white gills and Chlorophyllum will have a tapered base ands gills will be greenish/yellowish...definitely not white. More to the point...
