Observation 66300: Inocybe (Fr.) Fr.
When: 2011-04-25
(37.717635° -122.41953° )
Herbarium specimen reported

Notes: It looks like a Cortinarius. A local Cortinarius authority corroborated this as the genus. I don’t know the species though. The conical shape of the cap, the gills being spaced apart, the white cylindrical stipe look like Cortinarius.

Two days later there was a cluster of little Inocybes in the same spot. As far as I could tell, they never matured. I went back a week after that and there was no sign of them.

but apparently our common western var. lilacina is NOT an exact genetic match for the European species that bears the same and original name. Lots of European names were “borrowed” for NA species, but we are now slowly working on giving them back and creating some new and more appropriate ones.

STILL, until we get that better name through publication, may as well use the one with which we and many others are familiar.

is too a species found in the West…

Inocybe geophylla var. lilacina grows like weeds in the pine tree plantation I hunt just across the street.
a search here at MO shows plenty.
As for what this is….idk…sorry to butt in! :)

of course not, Christian,

we all speak for our own selves here.

I was just amused that Noah was so quick to jump upon the Inocybe sp. bandwagon after his recent remarks here about how it makes more sense to use the already known names, prior to an offical, published name change re: Morchella sp.

I do agree that our NA morels are one huge mess, and frankly, since they all eat about the same (except for those pretty tasteless as well as highly distinctive rufobrunnea) I really don’t care what ya call ’em, and plain old Morchella sp. is good enough for me, until we have a real way to tell them apart in the field. Western morels seem to be especially diverse; maybe not so much in the East? Noah?

when we get a published, good name for this locally well know as lilacina Inocybe, well then, I will call it by its new name. Easy peasy to switch names on MO. Anybody who calls up this sighting can also read all about the naming controversy, if they so desire.

Just because

Noah complained about that method, doesn’t mean we all agree…

Personally, when I can point to data that show (or strongly suggest) that two entities are not the same species (ie. all north american vs. european morels), then it makes sense to me to call them Morchella.

You can always name something like this Inocybe sp., and put lilacina in the comment line. That way it will show up in searches, and you don’t have to stick to the old name.

That said, it’s a matter of judgement and personal preference. I certainly won’t knock every old name, for reasons of convenience or where I can’t personally point to a paper or source of data that undermines that name.

plenty of instances where I’d use Inocybe sp.

this just isn’t one of them.

A matter of preference.

It’s Ok. It’s a matter of preference. It is in the lilacina group most likely. If you can put a gr. or aff. that’s perfect. I’m from the school of thought that when unsure about the exact name it is better to be conservative, but have fun either way.

whoah now…

Didn’t I just hear Noah complaining here about how we are all so quick to go to the basic Genus designation on our mushrooms when a name is in flux? This does indeed resemble what we call out here in the West our Inocybe geophylla var. lilacina…it has the umbonate brownish-tipped cap, purple when fresh; gills can be pale or purplish.

Sure, somewhere down the line someone could come up with a “better” name for this…but until then, this takes it out of the murky Inocybe depths and at least gives us a reasonable starting point.

I’m with you, Alan, don’t be so quick to cave! I’m going with lilacina group.

Otherwise they do look alike…

The point here is this – I can’t make a difference between the European I. g. v. lilacina and our local one. But the nrITS of the recent collections from Pt. Reyes showed significant differences and a new name will be issued. Nothing wrong with the lilacina guess though from a morphological standpoint.

I. geophylla var. liliacina

I was shown Inocybe geophylla var. liliacina on a trail in Pt. Reyes in December during “Mushroom Camp.” It must be local to the West. But this seems to be different.

It seems like Inocybe according to Dimitar Bojantchev who did microscopical analysis. New photographs have been added showing the microscope work he did.

Not so fast…

I. lilacina is not a W. American species. Close allies exist. An Inocybe sp.

The color of the lamellae…

Christian, I was considering that possibility too, as it really looks close, but the lilac gills do not look very Inocybe-like. Still, there is something else tickling the back of my mind, but I can’t quite put my finger on it down. A spore analysis will tell us everything.

Wow, weird.

It almost looks like a Cortinarius (intensely purple), but what about a very strongly colored Inocybe geophylla var lilacina (in that group, anyway).
