Observation 139595: Strobilomyces Berk.

When: 2013-07-11

Collection location: Rockingham Co, North Carolina, USA [Click for map]

Who: pete (petepann)

No specimen available

Growing from a dead Pine. Also, Why will the site not accept Strobilomyces floccopus? Has that nomenclature been flushed along with so many others? Why am I missing the memos?


Cap 74 mm. across. white color cap in contrast to numerous black, triangular shaped “spikes” or warts covering cap. Warts firm in

texture when fresh turning to a feltish texture with aging. Flesh grayish purple quickly turning black with exposure. (within 15 min

or so) 6.35 mm between top of stem and cap. Jet black pores 12.7 mm at longest point. Free from stem.
Stem 102mm in length 13mm at widest point (top). Tapers slightly narrower at base. Brown in color with black “scales” covering.

Flesh instantly a “mahogany wood stain” color when cut, quickly darkening to almost ( but not quite) black. Spore print: dark purple.
Pleasant “mushroom scent” when cut. Growing from a rotten pine stump. And I believe that about wraps up my observation on this

specimen. Regardless of the nomenclature outcome, he will for ever be “The Old Man of The Woods” to me.

All I have to do now is start saving money for a stamp! I know,well I assume, microscopes can range on up into thousands of dollars. But about how much would one cost, that would suffice for spore peeping?

Make a voucher!

If you can still collect it, then dry it and save it. If you want you can send me a bit of the dried pores (or the spore print) and I should be able to tell you what it is pretty quickly.

Oh. Wait a minute….

I just read the part where a microscope is needed. If thats the case, then I guess we WILL NOT be getting to the bottom of it after all. Aint that a kick in the …,.?

Thank You Nathan,,

for that extremely useful information. Somehow, contrary to all the documentation I have scanned through, I missed this news. I went back to the site this morning and collected the specimen. It is printing as we speak. Spore prints and detailed ID Info should be posted by this evening. I was under the impression that this was a common and easily identified species. I pass them up all the time on my hikes, only stopping for the more photogenic ones. It seems no fungi will be immune to a future name change. Amanitas, P. subbs to P. cints, And now they pickin on the “Old Man”. I starting to accept it as a “Mycology” thing.

S. strobilaceus is a European name

whether it occurs in the US is a matter of debate. There is also a question of whether the alternative European name S. floccopus is a distinct species or a synonym and if a synonym then which takes priority. However, since in this case both MycoBank and IndexFungorum agree, the MO community has accepted S. strobilaceus.

However, in North America, we also have to consider S. confusus (a North American name published by Singer) which is only reliably distinguished by not having fully reticulate spores (S. confusus spores: image 263823; S. strobilaceus spores: image 119269). So my rule of thumb is, if you don’t have spore information, just call it Strobilomyces sp.. I don’t know whether the distinction between S. strobilaceus and S. confusus are supported by molecular evidence.

How could this NOT be S. strobilaceus???

This is a BEAUTIFUL, picture perfect specimen. What about this is in question? I honestly need and would VERY much like to know.
