28 Classification of Mushrooms 28 1)Corticolous: Growing on bark of tree as bracket or conk, causes decay and rot of tree. Only few species are edible. E.g. Ganoderma lucidum, Fistulina hepatica 2) Coprophillus: Dung loving saprophytic fungi. It is adoptive to low lignin containing substrates, E.g. Bird nest fungi, Coprinopsis narcotica, Psilocye cubensis. 3) Lignicolous: Prefer substrates with high lignin content. it attacks tree trunks and other high lignin containing substrates and causes their decay.
