R. badius is the one that lacks clamps.. sorry.

I just thought I needed to mention tubaeformis as an option. In my northern area badius doesn’t exist, but I have seen tubaeformis a few times, which I recognize by its smallish size, cap rarely more than 5 cm, and its velvety, long and thin stem.

I didn’t see any clamps, but couldn’t say “no clamps” with confidence. Scoping was difficult (I have almost no experience with polypores) and I’m not sure that the hyphae I’m showing are “generative”.

P. badius does not have clamps and that’s what distinguishes it from P. melanopus, P. tubaeformis, P. elegans and P. varius—-according to MatchMaker and Krueger, Peterson & Hughes (http://link.springer.com/article/10.1007%2Fs11557-006-0512-y).

With the incomplete information I was able to give, simply Polyporus is probably the best we can say.

Did you see clamps like badius should have? I looked at the micro shot but I’m not sure if there are any.
