Chaga - Inonotus obliquus, infertile stage?

Post by Steve » Sun May 24, 2015 8:49 pm

Hi,
Yet another one from Longshaw Estate. Sally pointed this out on a Downy Birch. I've had it shown to me before at a good distance away - but I could see nothing fungal in the specimen of the "wart" or "canker" which I took at the time. I told the serious mycologist who named the lump as Inonotus obliquus that "I no notice that one" - and met a stony silence.
This one looked much more like the descriptions as being like like hard clinker. I crushed a bit of the black matrix and got fragments of very polypore-like hyphae. A section gave me some spongy brown matter which looked like mycelium. I only got hyphae up to 3 um wide - it can be up to 7 according to FOS I think. I'll look for the fertile stage next time we visit the site.
Cheers,
Steve

Hi,
I'm continuing to check out some of the more blackish, clinker-like warts on birch. This one was definitely not Chaga - Inonotus obliquus - microscopy shows no hyphae.

Birch Conk or Chaga? No.
