I'm pretty sure this is R. cyanoxantha. The gills were rubbery and flexible, not easily broken the way most russulas are.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Charcoal Burner

Looks right for the Charcoal Burner, however its very difficult to separate from other look-alike Russula's. You need to get hold of an Iron Salt crystal, this will help with this species as it will have a negative (starch) reaction a dull green/grey. Other similar species will turn a pinkish colour. You may be able to pick up or order a crystal from your nearst fungi group.

Thanks, Andy, That's really

Thanks, Andy,
That's really helpful. I'm at the point now with fungi where I need to decide whether I am committed enough to go down the route of microscopy to confirm IDs. An Iron Salt crystal sounds a whole lot more affordable than a microscope and all the books that I'd have to buy as well. Thanks again.

Iron Crystals

Bear in mind that the crystals only really apply to Russula's especially to help differentiate between the Charcoal Burner and close look-alike species. They can also be helpful with other Russula species such as R. vesca and R. heterophylla which have a strong, almost orange raction.
It can be an expensive hobby, as most hobbies are, but I feel worth the investment if it brings enjoyment and I feel you enjoy the fungi.
