Xerula radicata - Rooting Shank

Xerula radicata, Rooting Shank

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Agaricales

Family: Physalacriaceae

One of the early-fruiting wood rotters, Xerula radicata (synonym Oudemansiella radicata) is a tall and very graceful mushroom. The stem has 'hidden depths': this woodland beauty usually has as much of its stem below the forest floor as above.

The majority of wood-rotting fungi show a marked preference for either hardwoods or softwoods, but I have found Rooting Shanks under conifers and almost as frequently under deciduous broadleaf trees.

Xerula is a very small genus with just four species recorded in Britain, and of these Xerula radicata is by far the most common.
