Brown Rat

Coprinopsis pseudofriesii is a small, inky cap mushroom related to the shaggy ink cap, with a pale grey cap that liquefies at maturity. It grows on richly organic soils, old compost, and near buried woody debris in temperate forests. This saprotrophic fungus decomposes organic matter and woody material in its forest soil habitat.
