Summary: trees around

I checked what kind of trees are growing near this observation. The place is certainly in reach of Larix decidua, Picea abies, and Pinus sp. roots (all of them growing in cca 4-5 m (13-16 feet) radius). There grow also a small 3-4 old Malus domesticus and a few young Fraxinus ornus and Ostryra carpinifolia ‘bushes’, none of them taller than 2 m (7 feet) at an approximate distance of 3-4 m (10-13 feet). Seems strange to me.

Summary: There was no oak in the vicinity.

Oak is actually a quite rare tree here around. Most probable candidates would be Fagus sylvatica, Fraxinus ornus or less frequent F. excelsior, Corylus avelana and eventually a small Acer sp. (apart of Picea abies and Pinus sp.) As admitted, I am not attentive enough regarding this.

I checked to me available Slovenian references regarding B. satanas and B. luridus and their edibility. All of them claim B. satanas as poisonous. But one states that the poisoning is although unpleasant not life dangerous. B. luridus is claimed as conditionally edible in all of them. One has to cook them thoroughly. One reference even claims it is a very good mushroom. In spite of this I’ve never heard of anybody in Slovenia who would really eat them. But, many years ago I met some guys from Check Republic, who claimed they eat them.
Regards
Amadej

Summary: There are very tasty red pores.

In America for example I liked Boletus frostii for eating or Boletus subvelutipes.
In Europe I liked Boletus queletii, Boletus erythropus, Boletus rhodopurpureus and Boletus rubrosanguineus back in the time I still ate mushrooms. I don’t eat them anymore cuz I don’t eat my studying material (or sometimes my brothers ;) )
.Boletus luridus is medium quality.

Summary: Simon & Shuster’s Guide to Mushrooms is one example that advises not to eat this fungus.

Simon & Shuster’s Guide to Mushrooms advises: “Eaten in Europe; not recommended in North America because of the difficulty of accurate identification and reports of vomiting and diarrhea from eating this or related red-to orange-pored species.” I agree that no matter how many forms of proof you supply to people they are fearful of anything they have been warned of in the past. Old habits die hard no matter where you are in the world. I am curious as to the taste. Do they have a sweet flavor? Guess this general fear leaves more for the brave at heart to consume :) Kate

Summary: Exactly for that reason.

At least you should cook them more than twenty minutes is another advise and this one is a good one for mushrooms in general are not easily digestable. But there are no deadly poisonous fungi among our Boletes and the really deadly ones DO NOT STAIN BLUE or have orange pores!

Summary: Perhaps that’s because…

…many field guides give as a general guideline “do not eat boletes with orange or red pores that stain blue”. Or even, in some cases, “do not eat boletes with orange or red pores OR that stain blue”.

Summary: Europeans usually do not eat this fungus

it is said to be poisonous in combination with alcohol which I believe is nonsense (have tried without problems). And it loves growing under lime trees altho you can find it under a broad range of hardwoods …
Central Europeans are commonly as afraid as you Americans if fungi are turning black or blue on bruising etc. and you can teach them or prove them one thousand times that they are harmless most of them won’t believe you though :(

Summary: Did you note any Oak trees nearby?

I am under the impression that these mushrooms are generally not consumed in North America. Do Europeans eat these mushrooms? I find your images are very informative the detail is very revealing. Thank you.
