Todays word is Fungus. Any of a diverse group of eukaryotic single-celled or multinucleate organisms that live by decomposing and absorbing the organic material in which they grow, comprising the mushrooms, molds, mildews, smuts, rusts, and yeasts.
This isn't your usual fungus or mushroom as it's a lovely wooden one in the gardens at Kew. Somwhere nearby there was a huge wooden beatle too!!!!!!
