Moved from Eutrichillus canescens.

This is good. I spent an hour or so the other day trying to "see" the characters for E. canescens on a couple of E. pini I have from the Onion Saddle area. This makes sense now. Thanks for the correction.

Sure, sorry to put the wrong determination first, but glad I got Jim Wappes' input.

This is actually E. pini
Upon further evaluation and consultation with Jim Wappes, this is apparently the closely related E. pini. These species are very similar and the characters distinguishing them are not very clear.
