Hey. I'm from Madeira Island and I wanted to ask you guys, especially those with knowledge about the mushroom log cultivation, what you think about growing mushrooms on Eucalyptus? From what I gather through my online research, Eucalyptus kinda sucks... but that's basically the most predominant tree available here. Am I limited to Shiitake and Turkey Tail or is there any chance Eucalyptus will work with other fungi species as well? Hope to hear from you guys.
My son and I found an enormous fungus growing at the base of a live eucalyptus near our house back in the spring. Sorry I don't have photos, but it was yellow and I would describe it as clumpy in form, about the size of a football with 4-6 individual caps in a clump. Stalks were about 100mm and caps 150mm across. I'm pretty sure the tree is E nitens...there are a lot of them on the margin of the rugby field next door.
good question Hans, the problem with fungi is that they do take in "noxious" particles of their food and the fruits will hold onto those "noxious" compounds.
I would imagine that if the fungi fruit was found on Eucalypts there would be a fair amount of the oil or compounds from the oil in the "mushroom" and that eating it could cause gastric distress or worse.
Same goes for Yew wood (toxic compounds) however conifers are the usual hosts for chicken of the woods so that part of the statement should be suspect. (chicken of the woods usually isn't found on deciduous trees, lion's mane is)
The reason fungi do so well at remediation of contaminated soil, water and wood is because they do take up the offending molecules the mycelium will then purge itself by putting out fruits that take those compounds away from the mycelium so it can gather more of those compounds.
This is why no one recommends eating any of the fungi fruits from a remediation bed.
I'm not sure about eucalyptus flavor coming through. Individual fungi are quite limited in what molecules they can take up.
I have grown many oyster mushroom in quite fresh camphor laurel logs (which contains cineole, just like eucalyptus - as well as other aromatics).
There was no odd smells or tastes and an abundant harvest for years.
Oysters are not fussy about substrate.
If eucalyptus was expressed in the fungus grown, I would expect it to disappear after a few flushes.
Stamets points out the fungal proclivity for rapidly denaturing aromatics in Mycelium Running.

Eucalyptus is a native Australian tree and Australian mushroom growers have great success growing on it. They recommend it as a growing medium, and as eucalyptus is found everywhere in Australia it’s very convenient to do so. Some taste tests done in Australia found the eucalyptus mushrooms had the best taste! In Australia we even have eucalyptus candy.
