Tachyporus pallidus

This one appeared in my garden moth trap. The microsculpture on the elytra was extremely difficult to see - I couldn't make out a clear pattern but there was something there. It had a row of punctures along the suture but although I don't have a specimen of solutus to compare it to (and I can't find any good enough photo online that show this level of detail) I don't think these could possibly be described as strong punctures. I think the size of tarsal and penultimate antennal segments also support the ID as pallidus.

This found resting on a Comfrey leaf beside a river in the late afternoon.

This was swept from low vegetation. It was the first one I felt confident identifying although I didn't find it straightforward. The head width vs. pronotum length ratio was closer than I expected which initially set me on a path to atriceps, but I dissected it and the aedeagus didn't match that species and I realised my error. I don't appear to have taken any photos of the aedeagus unfortunately.

I didn't manage to identify the next two at the time and didn't retain the specimens, but looking at the photos I think they're almost certainly more pallidus - unless anyone disagrees?
