Observation 214184: Boletaceae Chevall.

When: 1980-08-27

Collection location: Battle Creek, Michigan, USA [Click for map]

Who: Scott Pavelle (Scott Pavelle)

No specimen available

This photo was taken in the early 1970’s by Ellis Becker and willed to the Western Pennsylvania Mushroom Club. Note that it was taken on actual film and there’s clearly some color shifting at work. It was supplied to me with the title “Boletus appendiculatus” but I have serious doubts about that ID. In addition to the colors being off, the mushroom doesn’t seem to be stout enough to match the written descriptions. I also have no evidence that Mr. Becker took the photo on the west coast (where appendiculatus is found) rather than in his native Michigan.

Can anyone provide a probable – or even likely – ID based on the photo? And if not, can you confirm that it IS NOT appendulatus?

Thanks in advance!

It’d be a shame if it can’t be used at all.

Color shift aside, it’s a lovely picture. And there’s something romantic about remembering old, accomplished-but-amateur mycologists like Ellis Becker. But if no reliable ID is possible, I guess I’ll have to live with it.

At least Walt had a chance to go back and visit an old friend he probably hasn’t thought about for quite some time.

This old pic is definitely red-shifted, which doesn’t help with the ID. Either way, there is not much info to go on to begin with…

But this does not look at all like B. roxanae.

it has the features for roxannae, Walt …

orange at the apex, yellowish context, streaky but non-reticulate stipe, yellow pores.

not a great photo, but a better match to roxannae than just a generic bolete.

I think IG called it.

Your old photo strongly resembles B. roxanae, which does occur in Michigan as well as many other places east of the Rockies.

B. appendiculatus (now Butyriboletus persolidus) was the old name for our Western Butter Bolete, which this clearly isn’t. The European butter bolete retains the original specific name. Here are many examples of them, so that you can compare to this photo:


Roxanae is a rather unusual find for most, so perhaps the hunter didn’t recognize it?

Fun to go thru those old photo archives and attempt to make sense of photos. Good call on recognizing that this is NOT a butter bolete.

Thanks for the kind words. I corresponded with Ellis and to my knowledge he never hunted much outside of Mich. This photo is probably not enough to make an identification but it is not. B. appendiculatus.


Which one?

First things first. We’ve never corresponded Walt, but I want to say that I love your photos and also the comments I’ve seen from you here on MO. Very nice work.

As to this particular comment, why would a European species be any more likely than a west coast one? Again, all I know is that Mr. Becker lived in Michigan and took the photo. There’s no evidence (yet – I’m in the process of examining his notebook) that it came from outside his region. OTOH, if you actual recognize the thing to species by sight that would be a big clue.

is a European species.
