I ate C. armillatus once or twice…
By: Dave W (Dave W)
2017-10-12 04:08:19 CST (+0800)

and wasn’t impressed by the taste. No idea about the potential presence trace/minute amount of toxin. I would not have thought any of the slimy corts were good to eat. I once tried iodes, and the taste was at best unappealing. Sources list C. trivialis as similar and possibly related to C. collinitus. I have found C. collinitus here in PA.

Thanks Ron

I cooked up a few pieces and it was very good, not slimy at all. All the specimens out here are pretty dry and it has a good texture. I just need to find out for sure if they contain that chemical. Thanks again for the link.

Cortinarius armillatus
By: Zoyd Wheeler (antizoyd)

I am finding a lot of this species in my area (Cape Breton Island, NS). Is it accepted as an edible species? I have read one report where it was found to have a very small percentage of that compound (whose name eludes me) which makes some of the other Corts poisonous.

As I recall (it was a long time ago) those C. Armillatus were nice firm buttons. This does not completey rule out that they could have been sitting around for awhile in that state, if the weather had been dry.

Actually, Arora has a bw photo of C. crocolitus; looks quite a bit like the C. trivialis pictured here. Birch, huh… along with species of Leccinum. Something new to keep in the back of my mind. I should probably see what I can find about these slimy banded stalked Corts possibly occurring here.

Dave, about triumphans
By: Irene Andersson (irenea)

Cortinarius crocolitus is said to be a synonym to triumphans, but I don’t know about the one pictured by Arora. Cortinarius triumphans can probably be found in Canada and the northeastern parts of USA, though I haven’t seen any other pictures of it from places outside Europe.. It grows exclusively with birch and prefers calcareous soil.

cortiphagy…the trick is to eat traganus when it smells like ripe pears rather than old goat!

I personally haven’t tried it at either stage, but the tip to its edibility was given to me by Dr. Michelle Seidl, who was working closely with Ammirati in the PNW on the study of Cortinarius. I just took her word for it. At least they are a distinctive mushroom! One of the few corts that I can readily put a name on, at any rate…

Cortchella esculenta?
By: Dave W (Dave W)
2009-03-01 00:01:50 CST (+0800)

Has (Rozites) ceperata been offically placed into Cortinarius? I certainly like these. Arora mentions trivialis and triumphans in the same paragraph (comments under collinitus). But his use of “triumphans” appears doubtful, as he inserts a “?” onto his own usage. So maybe this is a completely different species now? I’m guessing we don’t get it here in eastern US. I also just noticed that Arora lists C. armillatus as a good edible; which I tried and found to be “dirty bland” if that makes sense. The western version is probably better.

Favorite edibles
By: Irene Andersson (irenea)
2009-02-28 19:23:45 CST (+0800)

Among my personal favorites for the table are actually two species of Cortinarius: caperatus and triumphans.
But eating Cortinarius traganus?? I would never think of it, with that terrible smell.

By: Dave W (Dave W)
2009-02-28 12:18:06 CST (+0800)

Looking through my old manuals now, the only one I can find which actually recommends C. armillatus is McIlvaine (gasp!). So I suppose it may have been upon this recommendation that I once fried up a small panful (1992 as my notes indicate)… well this, and the fact that it’s a fairly easy to ID species and occasionally quite common im my area. They were, to phrase it in the appropriately McIlmaniacal fashion, the very best of the Corts! Translation: I managed to swallow the entire portion. My notes on the other two I have tried, C. ioides and C. alboviovaceus, include words like “dirt” and “detestable.” McIlvaine writes about Gyromitra esculenta, “It is not probable that in our great food giving country anyone will be narrowed to G. esculenta for a meal.” I think the same should hold for Corts.
Sliminess in and of itself is not a deterrent to the mycophogist. I have met people around here who actively hunt Hygrophorus flavodiscus and H. fuligineus for the table. These species are as slimy as it gets.

It is certainly attractive to the eye…

but a pleasure in the pan? I doubt it. I do love your description, tho,
bythenumbers…“slippery as an eel!”

I think it is probably safe to say that folks HAVEN’T tried this one. And potentially deadly, or unknown or simply unpalatable are all good reasons not to eat most corts. I don’t know of a lot of folks in the habit of eating any corts, or experimenting with corts for the table, not even the temptingly slimy capped ones…altho nothing sez dinner like a thick coat of snot!

I am aware of very few corts that are eaten here in North America (the short list includes traganus and the delicious Cortinarius caperatus, formerly Rozites caperata). But a gastronomic history of experimenting with them? Nah. America is still mostly a fungiphobic society, European transplants and born-again mushroom fanatics notwithstanding.
And most folks just can’t ID corts (our stellar Dimi is the exception, not the rule), and our number one rule as mycophagists is, if ya can’t ID it, ya shouldn’t eat it!

But there’s a MacIlvainean borne every minute…so if you must experiment, at least let us know how it turned out. Eating this cort would not be a trivial event.

Probably edible… Not sure about the taste though.

If these were poisonous we’d know by now. These are well
distributed, easy to id, rather prominent, tall, distinctly
girdled Myxaciums in Section Collini, which are one of the first
Corts for people to learn. I’m sure someone ate them already. A
number of Corts are being eaten with no ill effect.

We should concentrate on those that are not edible — these
include the Dermocybe, the Orellanus group and most notably a few
rather rare members of Phlegmacium/Fulvi that have turned out to
be deadly.

Some Myxaciums (vibratilis & Co) are bitter, but they’re in a
separate Section that appears to be far less related than the
stipe gelatinous morphology suggests.

Many Corts have a leafy taste. I’ve tasted several hundred Corts
in the process of identification. Few have a pleasant taste -
like C. praestans, which is regularly eaten in my part of the

Bythenumbers, I’m sure that someone from California could give you a more exact answer, but I would recommend against eating any Corts. Years back, when some manuals listed some Corts as “edible”, I tried a few. Each one tasted horrible, including the slippery, and very pretty, C. ioides. Arora writes that some types within this particular group of Corts are “untested.”

Arora pretty well describes C. collinitus group (C. trivialis)… “ring of hairs near the top of the stalk,”

Checked my Bessette/Bessette/Fischer manual, and here’s a few offerings regarding Hebeloma radicosum, “(cap) viscid when fresh… various shades of yellowish tan… often rimmed with partial veil fibers.” “(Stalk) sheathed from the base up to the ring with pale ocre-brown to pale cinnamon fibers and cottony scales over a whitish to cream ground color…. partial veil whitish, fibrous, leaving a superior ring.” “Spore print rusty brown to cinnamon brown.” As usual, mushrooms of eastern NA and western NA seem to mimic each other in rather unpredictable ways.

So sorry to bother

So sorry to bother, it is said many Cortinarius should not to eat because poisonous. But how about the slippery ones? This one is very lovely and I want to eat it if lucky enough to see it. Can it be good if it is fried?

By: Dave W (Dave W)

Sounds like this is a fairly common Cort of NO CA. Is it typical for this mushroom to have such a well developed ring? That’s a feature which I do not generally associate with Cortinarius. I do now notice the bluish tinge to the gills in these excellent photos. Bluish or purplish tones are certainly colors which I find in many of our local Corts here in the eastern US. I’ll check my Arora manuals when I get back home today.

Most typical C. trivialis
By: Dimitar Bojantchev (dimitar)
2009-02-28 01:56:59 CST (+0800)

As typical as they come in No. Cal. under Live Oak.

These have very large, coarsely verrucose spores.


P.S. Dave W. pay close attention to the bluish gills as this is an important diagnostic characteristic that can often help you navigate the Genera.

Hello “bythenumbers”!
By: Irene Andersson (irenea)
2009-02-28 01:52:43 CST (+0800)

I must agree with you, this Cortinarius has a beautiful cortina with glue from the cap margin.

Is beautiful Cortinarius, sorry!.
By: bythenumbers
2009-02-28 01:36:28 CST (+0800)

Very sorry to make intrusion like this. Very lovely photos! But I know some little things and perhaps can be helpful some more. This one cannot be Hebeloma as proposed Dave for following:

1. Pileus appears to be so viscous like eel or Cortinarius.
2. Lamellae bluish in the youth.
3. Cortina shows bright rust-brown colour (spore) like Cortinarius, not
so much found in Hebeloma.
4. Stipe and Cortina has much sticky matter on it as though viscous.
5. Stipe showing many belts like rungs of slippery eel ladder!

So it look like C. trivialis or similar but I dare not say exactly more because not look at spores. Many people this site have microscope and make such very beautiful photos of spores, cheilocystidia, ixotrichodermium, clamp connections. I like very much. But sorry, I have not enough money for microscope or library. So I must try another way to learn. I look at photos very, very closely, for many minutes. For example, I look at cortina in the photo with big magnifying glass but so sorry, can see only pixels, no spores.

The ring appears to be unusually well developed for a Cort. So I did a quick search of Hebelomas; knowing that there are a few ringed species. H. radicosum may be a European species (not sure). But a few of the pics included in the link look very much like the specimen seen here…. Just checked the link, and it does not go directly to the page with the Hebeloma. Does this specimen have a rooting stalk?
