The mushroom was found near Gatun Lake, about 50 meters altitude, tropical climate conditions. Dr. Meike Piepienbring, said maybe is a unknown species of Tylopilus

after consulting a couple of dictionary references, I accept your latest comment about my liberal usage of the word “endemic” throught my comments as valid. Thank you for your correction and making me a better writer. Perhaps, replacement words like “distributed” or “limits of distribution” would be optimal in the given context…

My point was about the word endemic

In a biogeography context, the word ‘endemic’ has a stricter meaning. I realize that the common usage is a bit broader but we are talking about biogeography here…

So when you write:
“…12 known Boletellus species endemic to the continental NA”

I just want to clarify that (in the strict sense) at least one and perhaps others of these 12 species do NOT qualify as endemic.

The main example I am thinking of is that Boletellus ananas occurs in North America but ALSO appears to have a wider tropical distribution into the northern parts of South America, and possibly also Asia.

There you go,

Myxomop,— the poor man’s, or ersatz, version of hot chocolate. Obviously, I cannot afford the real thing. :-)

what I meant to say was that attaching a Boletellus sp. name with a high degree of confidence to a bolete that doesn’t appear to fruit in “our neck of the woods” – and thus unlikely to be recognized by amateur bolete gurus because it doesn’t look like any of less than 12 known Boletellus species endemic to the continental NA and described in popular references, such as the big bolete book – without providing some supporting evidence is unconvincing. In other words, what are the discerning macro- and microscopical features of the pictured bolete that necessarily make it a Boletellus sp. rather than a Tylopilus sp.?

By hot chocolate, I mean a drink prepared from cacao powder that to me looks like pinkish-brown. Unlike yours, my eyes are not a spectrophotometer, so please excuse my skewed color interpretation.

First of all, I agree with you that it looks nothing like Boletellus.


Endemic has a very specific meaning… Assuming that’s the meaning you intended, the sentence here states that because the range of Boletellus is NOT restricted to continental North America, the proposal that it might occur outside continental North America is questionable. That’s a non sequitur.

Also, I’ve never had pink hot chocolate.

Why Boletellus?!

Stamping “recognized by sight” onto a bolete species that apparently is not endemic to the continental North America without providing any rationale for such an assignment is unconvincing, to say the least. Why would a Boletellus sp. have its pore mouths colored like hot chocolate? Would you please care to elaborate?

can you be more specific

than “Western Panama”?

Lovely bolete!

The fake universal veil remnants on the cap almost make it look like an Amanita sp. from above. Roy Halling may know this one ─ he frequently travels to exotic places in search of even more exotic mushrooms. :-)
