Walt makes a good point. These mushrooms were found in an area that flooded less than a month ago. If such a habitat is unusual for P. squarrosa, but common for P. squarrosoides, then these mushrooms are probably the latter species.

Scary looking little guys — looks like they’d whack you if
you reached for them!

you didn’t think this mushroom ID stuff was for sissies, did ya? ;)

it’s a great way to keep humble…those mushrooms will always fool you…eventually. and there’s nothing like a public ID splat for a humility reality check.
but as long as you’re not eating your mistakes, so what? if you are eating them, be very very afraid, or at least, be very very careful.

Walt gave you the key to this ID…you must assess the cap cuticle, not the warts on top. Of course, you will need the mushrooms in front of you to do this.

pretty soon we’ll be collecting everything we photograph, eh? that’s really the only way to be sure of your ID, asssuming that you have the right keys or right expert mycologists at hand, and that the species has actually been described…otherwise, no worries! ;)

When they mature, I’m betting it will be tacky to viscid under those scales.
My experoence with P. squarrosa is that it is a more northern species usually on Populus or conifers. On a flood plain in SE Ohio would be unusual.

squarrosioides has a viscid cap; squarrosa a dry one.

This is the common species in Ohio. My favorite oides name is Cortinarius iodeiodes which when said fast sounds a bit like yodeling!

You tell ’em, Dan!

(I couldn’t agree more. :)

not viscid

I’m not sure how to distinguish between P. squarrosa and P. squarrosoides.

The latter name, BTW, is a really bad name for a taxanomic category. The specific epithet, if descriptive, should tell us something about the named taxon that distinguishes it from other taxa in the generic category. In Philosophia Botanica, Linnaeus explicitly discourages the use of the suffix “-oides”, because it merely conveys that the species is like some other kind of thing, rather than indicating how it is different from other species in the genus.

Sometimes, a name ending in -oides is only mildly problematic. Amanita phalloides, for example, is the species of amanita that resembles a phallus. Other members of the genus also resemble phalluses, so the binomial does not serve to define the species per genus et differentiam, but the same is true for most descriptive binomials. Gymnopilus luteus is not the only yellow Gymnopilus, and Psilocybe cyanescens is not the only psilocybe that becomes blue. The character of being phallus-like is no more or less distinguishing than being yellow or becoming blue.

However, real problems with the suffix are manifest in the present case. We have Pholiota squarrosa, which distinguishes itself from other pholiotas by having a squarrose cap and stem, and then we have another species category, P. squarrosoides, which distinguishes itself from other species of Pholiota, presumably, by being like another species of the same genus, P. squarrosa. This name is ridiculous!

why squarrosoides – viscid, with an aromatic/spicy smell..?
