Trichaptum spp. in NA

I spent most of the day yesterday researching Trichaptum and trying to distill them down to salient characteristics. Here is what I have so far: Trichaptum "Key" Now I need to try to use it! I just copied down what one of the good European people said on someone's iNat post (in Europe) just to see if it holds up over there. It's at the bottom of this document.

For us in North America, I don't think it will be very easy to do anything but "field" ID the Trichaptum without micro or exact tree ID. Maybe, we can figure out abietinum, fuscoviolaceum, and laricinum on conifers. T. secor and trichomallum seem fairly easy down south, though there are two other names being used down Texas way (Jared McRae, and Aidan Campos) that I have not included. I'm am interested in the couple Alan has from Mexico too as he's listed Ricardo Valenzuela (no, not Richie Valens) as having confirmed them, but I didn't include them either. Danny Newman has a cool one from S. A. So far I haven't seen any pics of T. trichomallum. Micro seems so close for so many of them. A good thing to start doing for collections on Maple would be to check for a gel layer between the context and the pores (would require microscopy, I think), that way we could separate any T. abietinum that may be on them. That's also supposed to blacken with age (pore surface?).

The link at the bottom gives a 404 error.

Looks like I need to edit my IDs and comments for Trichaptum. The fact that biforme grows on conifer escaped me. I sent specimens to Dabao that I thought were T. abietinum for a project in Norway. Who knows what I really sent! Aren't T. subchartaceum and T. larcinum boreal? We wouldn't be likely to see them except maybe in the Adirondacks. At least the spore size on T. subchartaceum is different. I'll be taking a closer look this year!

We have lots of T. subchartaceum here. I think it is one of the easier ones, though microscopy is still necessary. I sometimes feel sure due to its habit of getting a very dark brown pore surface and obtaining large, but not dentate states. Much of the quaking aspen or whatever it is here is infected, and I believe I have it seen it on big tooth as well. I have been identifying the few gilled ones that I have seen as T. laricinum in the past, but I'm not sure now looking at what they call T. fuscoviolaceum in Europe. It is quite strongly gilled. Here, what people call T. fuscoviolaceum is really quite a stretch sometimes. I'm definitely not at the point where I can recognize anything yet. I tried to highlight where things might be telling or not. I just hope I have broken my bad habits of identifying everything as either T. biforme or T. abietinum though. I'll edit that link out, thanks, but what I meant to have said was that at the bottom of the key I added the easy info the "European" guy had written regarding this. Somehow, I don't think it will be quite that easy here.

Well, you've definately broken me of the habit! Thanks.

Good stuff. Exciting to figure out what I've found on white pine with gill-like underside.
