A parasitic fungus that produces clumps of honey-coloured toadstools at the base of trees. The black hyphae invade a tree, causing decay or death and spreading out to other trees.
Armillaria mellea, family Tricholomataceae, class Hymenomycetes‘These are highly esteemed, including the ink caps and honey fungus.’
