Strange host jumps..

Very strange if it isn’t known from other hosts in Wisconsin and Michigan..?
In Canada (and here in Scandinavia) it’s a parasite on almost every kind of broadleaved trees. It seems most common on birch here, but the reason is simple – birch is the most common tree. Maple and poplars are easy victims too.


Interesting host jumps

Interesting that in northern Wisconsin and Michigan this species (or at least what we’re calling this species) grows exclusively on yellow birch (Betula alleghaniensis).

Thanks for catching that!

I had misread Arora and thought that C. purpureum was associated only with conifers. Now that I see that it’s on hardwood, this ID seems right to me.
