Tricholoma dulciolens

A few pics of T dulciolens which was my long skinny version of Matsutake for many a year.

Currently there is a question on whether these mushrooms have been exported from one of the Nordic countries to Japan as a Matsutake type produce, as Henrik in his comments below and other sources point out Tricholoma dulciolens is very rare in Scandinavia and probably in Finland as well so still curious on the link I added in comments below which makes the claim of T dulciolens being an imported item in Japan. I guess the good news for us folks here in the Maritimes is our mature spruce in a few different soil types usually in our near wetlands do produce some of these mushrooms, though here as well they seem a mushroom which would not be near common enough for a commercial harvest at least from what I have investigated thus far.

Usually when gathering you will only see the caps and then it is time to gently lift in agreement with the stem’s underground angle, notice a few are left as they are, very unwise to attempt to take all of anything.

In the deep moss there may be some of these and also the Matsutake below the green surface so walk soft, don’t walk directly to the mushroom you see, plan a path of least disturbance, all foods deserve our respect and this group almost seem to demand all your senses be fully awake and in tune.

    Nice pics and info,, could i email you pics of a few ” matsutake ” type mushrooms that i found for you to maybe identify?

  2. Henrik Sundberg October 12, 2015 at 12:09 pm #

    The mushrooms that are exported from the Nordic countries are true matsutake (T. matsutake) and nothing else. T. dulciolens is very rare in these countries and grows in a completely different habitat. I know since I have been involved in the export from the start.

      Thanks Henrik, this recent pdf article which I think you will like ( http://www.nlmushrooms.ca/omphaline/O-V-6.pdf · ) agrees with T matsutake being the correct name for the northern European Matsutake and goes on to state our (NA east coast Matsutake) is not T magnivelare but also T matsutake though the name change has not taken place yet at our most popular eastern NA mycology websites, hope it does soon as I would also prefer to use that name. Tricholoma dulciolens seems a different story and also and important part of the first NLmushroom article, also to note is a (not so new) joint research project by Japan’s Ministry of finance and customs from 2008 which claimed they at that time imported T nauseosum / T matsutake from (Northern Europe) T caligatum from ( Europe ) and T dulciolens from (Nordic), here is the link which should appear first on a google search. Nordic as you know takes in several countries and they do not detail which country or area within they were buying from. http://www.ffpri.affrc.go.jp/labs/matsutake

        Hi again,

        Yes, I have heard from Gro Gulden about the “real” matsutake in Eastern Canada but since it is has a quite different stature and colouration compared to Asian and European matsutake, and since their study was based on a single genetic marker I am not totally convinced of its systematic position. The authors also admit that it might prove to be a discrete species when several markers are taken into consideration. Their comparison of colouration between European and Asian matsutake does not hold good either. Believe me, I have seen many, Japanese, Swedish, Finnish, Chinese, Korean etc. matsutake and they are very variable in colour and therefore indistinguishable, although some Japanese matsutake gurus claim that they can tell a Japanese mushroom apart from others. I doubt it!
        As for the exportation of T. dulciolens from Northern Europe to Japan, I found it so unlikely due to the rarity of the species in Europe that I had to check the source. Fortunately one of the scientists mentioned happen to be a friend of mine, so I asked him. Below I have pasted his answer.

        “Dear Henrik,

        I have asked FFPRI staffs (Dr. Hitosshi Murata, Dr Hitoshi Neda).
        Their reply was that there is no valid data to be imported T. dulciolens to Japan.

        Therefore, I required them to be changed the description on their web site.

        Regards,
        Akiyoshi”

        I’ve edited to acknowledge the info we have this far on this post and I appreciate your help to clarify things. On T dulciolens would you agree if was a common wild mushroom in an area of the boreal forest the potential is there for it to become a popular edible at least for Japanese market were they are familiar with this type of choice product?

        I cannot tell how your American dulciolens taste like, and I have only tried the Swedish once. My impression then was that it were more perfume-ish than matsutake and therfore not so pleasant. But I guess you have tried it in Canada, then what is your impression? The authors of the dulciolens article seemed to like it. My experience of the Japanese market is that they are very picky. I know from our matsutke dealer in Kyoto that magnivelare is considered to have a good scent (according to him even better than the real deal) but an inferior taste. The price, as you are aware of, has fallen substantially for magnivelare but as it is still exported to Japan it is still worth the effort obviously. The only other matsutake I’ve seen for sale in Japan is mexican (Tricholoma sp.). Our man in Kyoto have told us that you sometime could find Turkish matsutake (T. anatolicum) as well. Neither of these two species fetch very high prices and I guess the only reason they are exported is that the pickers are happy with what ever they get paid. So, if the Japanese find dulciolens palatable and are willing to pay you enough money it could be worth trying. But I have to say that it’s not easy to export to Japan even if you have real matsutake. The logistics (at least from Scandinavia) is a major issue and it is also very expensive with express air freight. My conclusion is that it will be very difficult to make some profit on the export of dulciolens to Japan. We have problems even to reach breakeven most years since the matsutake production in Scandinavia fluctuates a lot. The minimum amount to ship usually lies around 50 kg, below that it’s not worth it. Most Japanese companies won’t buy from you if you have less than 500 kg to offer. So my advice is to try to create a market in Canada (and perhaps USA) for dulciolens. If you could get som fancy restaurants interested you might get quite good payment. Low production years here in Sweden (and Finland) we sell to top restaurants in Sweden and Denmark instead of to Japan.

        Best regards,
        Henrik

        Excellent info, very pleased you have shared this here with us, many folks who pop into this blog will gain a better understanding of the workings of the wild food market locally & internationally. I’ve noticed you’ve been involved with some interesting discoveries especially Lyophyllum shimeji, Lyophyllum of any kind are rare in the Maritimes of Canada, though I do find a few of them and Hypsizygus and they always peek my curiosity, I’ll add a few photos at the bottom of the Tricholoma dulciolens post for a few days of one of the Lyophyllum I’ve collected as it may be something interesting or just L decastes? Thanks again and best wishes in discovering more world renown mushrooms in your homeland.

    My pleasure. It’s always fun to discuss matsutake and its allies. Yes, Lyophyllum shimeji got a lot of attention when we found it here. We have not been able to exploit it commercially although it’s very common in the northern parts of Sweden in certain years. We hope that we will be able to sell some to top restaurants in the years to come. Shimeji is less suitable for exportation because it degrades faster when stored and it is also very often totaly ruined by larvae. By the way, I recently heard from Paul Sinclair (Alberta Mycological Society) that shimeji has been encountered in Canada some two years ago. Here in the Nordic countries the best forests for shimeji are the same as for matsutake, very nutrient poor pine moors covered in reindeer lichens. I guess you have these kind of forests somewhere in Canada as well? So if you are foraging for shimeji and “real” matsutake these are the kind of forests I think you should look for.
    It is impossible to tell what kind of decastes-like Lyopyllum you have found. The decastes complex is still poorly investigated and there are probably several similar species to sort out. Also, it is not clear what Elias Fries meant by decastes since there is no type specimen connected to the name. But in his description he mention that it was found growing under an oak tree, which could imply that the true decastes is what we find in parks, grasslands and decidous forests and that the ones growing with spruce (that also differ genetically) should be called something else.
