Thelephora penicillata: The Ultimate Mushroom Guide
About The Thelephora penicillata Mushroom
Thelephora penicillata is a species of fungi belonging to the group Basidiomycota. It is a kind of earthfan fungus that forms rosette-like clusters among mosses on the forest floor, most often under spruce trees. These short-lived fruitbodies can be found from late summer through to the end of autumn.
It is fairly common in wet acidic conifer plantations throughout Britain and Ireland; it is sometimes found in mossy areas under broadleaf trees. This woodland fungus occurs throughout northern mainland Europe, and it is recorded in Russia and North America.
First described by Christiaan Hendrik Persoon, and given its simplistic Asian name by Fr. hadton 1821.
Other names: Urchin Earthfan.
