An unusual spring find for CT (usual in Aug.-Oct.) with Larix sp. for S. grevillei. The pumpkin orange cap is one form we find while the chestnut reddish brown cap is what we use to call variety clintonianus. I yield to the molecular taxonomy experts about the name for this taxon in North America. KOH in cap-drk olive then black, dissolving the flesh.NH4OH on cap- cherry red, then fade to cinnamon. NH4OH on flesh-cherry red, then fade to dull blue/green.

You got to the bottom of this — the origin of the term (unless there is evidence to suggest it predates 1958) and it’s true meaning. Now we know how to apply it correctly.
So the picture on p. 16 of NAB is an accurate depiction of pseudoreticulation, and Scott’s obs 242156 is another good example of it. So, suilllus can be reticulated, too, just like many of its relatives in the big sister family, even though one of the defining and unique features of this genus is a different type of stipe ornamentation — glandular dots.
…verbatium from Dick and Snell “A Glossary of Mycology” (1958). The distinction is one of origins, that is morphogenesis. Where the network originates determines whether it’s real or pseudo….“Pseudoreticulate- falsely reticulate (of the stipe of Boletaceae) having reticulation that results not from the attachment of the tube walls to the stipe in the early stages of the development of the carpophore, but from tearing or stretching of the pellicle or that is caused by the anastomosing of ridges”. Conversely…“reticulation- having a network resulting from the attachment of the tubes to the stipe in the early stages of the development of the carpophore”…By these definitions it seems clear to me that the illustration below in my observation is a true reticulation in the space between the annulus and the pores. For people that speak common language you might as well say that reticulation is the footprint of tube walls found on the stipe. I find it odd that NAB doesn’t mention this rather obvious feature for S. grevillei. It’s interesting (and always informative) what Alex Smith says in TBOM about S. grevillei…“distinctly reticulate above the annulus from extensions of the decurrent tubes…”
I will hear out your arguments at NEMF while holding a peace pipe in one hand and a beer bottle in the other and having my escape route mapped out prior to it. :-) Probably not worthwhile to turn our first vis-a-vis into something it was never meant to be. :-)
Here is another example of pseudoreticulation in suillus: obs 152692. Incidentally, this happens to be my first sequenced bolete ever. Something very close to S. brevipes, and that’s as close as it will be according to T.D. Bruns until we expand our understanding of the genus through other relevant loci.
not arguing with you here, just commenting. I will save my future arguments for when we meet in person at NEMF this summer! ;)
You are a fair and worthy adversary (and friend?), whom I respect. And I do so love arguing taxonomy with the not so faint of heart.
I was going to just use the example of the dual helix discoveries as one of great minds thinking alike independently, but then saw further parallels in the fact that one of the researchers in that story was a woman who, despite her own considerable contributions, was very badly treated when she had the temerity to speak out strongly. Sit down and shut up, Kamala! The more things change, the more they stay the same.
You are well familiar with all of the players in the current myco-psychodrama, Igor, but you are wise to stay well out of it.
This brilliantly red capped suillus (!) is far more interesting.
…but as I say at this point in life it usually doesn’t matter to me if I’ve made a word up or simply dragged it out of the memory banks…as long as I’m being understood or the words work together to convey some kind of coherent idea.
the connection between ‘pseudoreticulation’ and sexism in science, Debbie, but I don’t think I want to know. :-)
Also, I didn’t say you should care about who first coined ‘pseudoreticulation’ in mycology (apparently the word is used outside of this field), just pointed out that it’d been mentioned in classic bolete literature.
just had never heard the term before, so thanks for the introduction.
besides, great minds can hit upon the very same idea independently.
check out this fascinating story about Crick and Watson and the brilliant Rosalind Franklin. Another sad testament to sexism in the sciences. I understand that Rosalind was quite outspoken, too, and rubbed her male colleagues the wrong way (mostly by actually having the nerve to behave just like them!).
And yet, isolated by small minded males and all on her own, she still did great things.
…has already been in existence since at least 2000 — see NAB, p. 16.
…maybe my recollection of where I may have first heard that word before is so dim that I only think I made it up…I so frequently make up words to suit my immediate purpose that I’m often not clear if I just invented a word on the spot or I dragged it out of some deep recess of my brain’s memory files… if it’s sterile tissue then it’s a neologism…pseudo-reticulation…if there are basidia there then it’s just decurrent pores mimicking the morphology of reticulation…
is a new vocab world for me! Thanks, Bill.
