Phlebopus marginatus – Salmon gum bolete

Phlebopus marginatus has the largest fruiting body of any mushroom in Australia.  It is a truly spectacular mushroom.  I am including it here as it is recorded as being edible, but the sheer joy of the whole growth event may surpass any pleasure from eating it.

In Western Australia it is known as the Salmon gum bolete, and  Roger Hilton has recorded it as being edible.  The pictures below, however, are from Victoria  (thanks lizza)

It grows in rings.  These might be described as circles of giants.

The actual size of an individual mushroom can be up to a metre in diameter.  This picture shows one in comparison with a block splitter that is 800 mm in length.

    Can you call me Re these Boletes I am very interested in getting some specimens,
    happy to pay for time and postage.

    The intent is to try and propogate it and get a good australian product going.

    Hi, We would love to contact you as we are beginning to find lots in our preschool. we have been taking photos and recording where we find them with children, and have even been on walking excursions to seek out unusual fungi! We are located on the mid north coast, 20 mins south of port macquarie.
    Regards,

    Please, could you send me the original description of the species because in Guatemala we have found a very similar one but as huge as yours! however the fruitbodies come out in the same amount! it’s fabulous to see that!
    Thanks a lot!

      Hi Roberto,

      I am fascinated to hear that you have a similar one in Guatemala. I am sorry but I don’t have an original description of the species. How much information to you require? I see that you have one giant mushroom there, Macrocybe titans, but that is a gilled fungus. Phlebopus is a bolete, so it has pores, not gills.

    Yesterday I found a field with large salmon gum bolete . I took some photos and picked a couple. I cleaned and prepared one, removed the stem and spores. I cut the cap into 5 ml slices and fried them in butter. They crisped nicely and retained an interesting soft texture. The flavour was subtle and delicious ! Today I might try them with some sage and a little Pinot Gris! Anyway, I had no ill side effects and I’m still here! Kris Fun Guy.

    Hi Kris or Andrew,
    Would you mind emailing me so that we can organise to get some to me so I can try and propogate it? Happy to pay postage and a bit of time to be fair.

    My phone number is same as above.

      Hello Richard,

      I thought that I had replied to you before, but I see that I didn’t. My apologies.

      Because it is a bolete, cultivation of this fungus would require innoculation of a host tree. You cannot simply clone it and grow in on a substrate like you would with some other fungi.

      Cultivation of boletes like this is at best difficult and is generally considered to not be a commercial possibility.

      Cheers,

      Morrie

    I have bought some oak trees, I guess its whether someone is willing to try at the picking end. Even just send me a print, leave some paper out during the day but a mushroom would be better or the pores scraped off from underneath.

    I am about to buy some Pines to try and innoculate as well.

      I am afraid that oaks are unlikely to be suitable host trees, Richard, nor pines. As the name suggests, these mushrooms are associated with Salmon Gums. They are likely to be associated with other Eucalypts too as they occur all over Australia. But not in northern hemisphere deciduous woodlands.

      The simplest strategy would probably be to plant suitable host tree seedlings in the area where they grow.

      If bolete cultivation was simple and economical, we might expect to see more plantings of trees to grow Boletus edulis, but I am not aware of any such plantations.

      Perhaps someone can supply you with a spore print, but I don’t have access to these fungi and they are fleeting, like all fungi.

        It would be worth having a go at inoculating Eucalypts with the spores.

        Don’t be put off by what people or books etc say about not being able to grow mycorrhizal fungi.

        It’s only by trying that you’ll really find out.
        …won’t be reliable enough to try as a business proposition for growing them which is one of the reasons why you dont see big forests planted just for mushrooms.

        But I’ve seen and heard of examples of where they have been grown successfully.
        Truffles are a good example of a more widely ‘cultivated’ mycorrhizal fungi.

        The financial rewards for a ‘success’ there are a big enough carrot for people to have put in the research and effort to get the results that they now achieve.

        So…..plant a forest of pines , oaks , birches inoculated with
        Boletus edulis, B.aestivalis, B.aereus , Amanita caesaera, chanterelles, milk caps, Leccinum spp. etc.

        …and look forward to going mushroom hunting with your kids, or maybe your grandkids.

        It’ll be worth the wait, and what a sense of satisfaction when you get your first harvest.

        Sure. Neale Bougher describes innoculating Eucalypts with mycorrhizal fungi somewhere on the net.

        This fungus is not exclusively Australian however. It grows in surrounding countries.

        It sure creates a lot of interest!

        Seems that I am wrong about this. Phlebopus is not necessarily associated with a host plant and it can be cultivated as a saprobe. This is done in Southern China.

    Very impressive pics.

    My brother found one of these many years ago growing in
    the Victorian Mallee, while out on the motorbike.

    At first he thought it was a horse saddle that someone had lost.

    On closer inspection it turned out to be a giant bolete that had grown and pushed up a thin tree root which distorted it into into the shape of a saddle.

    With the same colour and texture of leather, what else could it have been?

    We call the Slippery Jacks here in Victoria, and they are very edible. Great aroma after dried out and stored away, ready for that next mushroom risotto.

      morrie2 said,

      If you called them Slippery Jacks, then you would be quite mistaken. For someone in the food business, I find such a mistake rather startling to be honest. You can read about Slippery Jacks here.

        MrSpikie said,

        Yes, thank you, I do stand corrected, and also later found the further post of Slippery Jack and realized my error. We do not sell mushrooms, nor do we cook products past the humble supermarket buttons, nor do we intend to. I am a novice to wild mushroom pickings and can only strengthen my knowledge from more wiser persons such as yourself, thank you.

    I have a large quantity of these mushrooms currently growing in Illawarra Subtropical Rainforest under a variety of different tree species and also in grassland. They don’t only grow under Salmon Gums. They appear to prefer dark conditions and grow after heavy rain.

      Hi Erika,

      Thanks for your comments. It is very interesting to hear that you have a lot of them growing. They are certainly not restricted to Salmon Gums; that is just an observation that has been made in Western Australia. The ones illustrated are from Victoria. Is there any chance that you could take a spore print of one?

      Cheers

    Phelbopus are coming up on the East Coast, I tried some while young and firm, they have a nutty flavour and good texture. The mature caps I tried just cooked to mush and the flavour was lost.
