Yes. I documented the fruiting body a few days ago. The fruit body is extremely easy to overlook unless you’re searching for it. http://mushroomobserver.org/286020?q=8Ran

Thanks for the explanation. It’s all clear now. Have you ever seen f. obliquus?

I. obliquus f. sterilis refers to the Chaga itself. The fruiting body which forms separately is called Inonotus obliquus f. obliquus. I’ve provided some more information on the name page of the former. Inonotus glomeratus and a few other species are also known to produce sterile conks on occasion. I. obliquus f. sterilis (chaga) forms on living hosts as a result of the host trying to seal off the point of infection. Once the host dies; I. obliquus fruits, spreading its spores to another wounded host, starting the cycle over again.

Thanks, Herbert

Why f. sterilis as opposed to the garden-variety chaga?
