Interestingly it’s only been the monarch since 1967 before that it was Britannia
I’ve been asking the question generally because whenever wildlife gets a mention fungi and plants get left out of the conversation.
New Zealand has the Skyblue Pinkgill Entoloma hochstetteri on one of its notes.
I’ve had various suggestions including Jubilee waxcap Gliophorus reginae ( a royal connection), the Oak polypore ,Buglossoporus quercinus (a flagship conservation species growing on old oaks) , Fly agaric, Amanita muscari (obvious and easily recognised).
Also the Ballerina, and the Stinkhorn.
I recently finished a stint on the BMS FEO committee and I’m still in the UKFD working group so this was just a light hearted way of raising the profile of the fungal kingdom.
Flora,Fauna Funga!

p.s. I think you’re probably right about squirrels and robins.
