Steccherinum ochraceum

Steccherinum ochraceum

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Polyporales (insertae sedis)

Family: Meruliaceae

A wood-rotting crust fungus of deciduous hardwoods, this attractive fungus produces its spores on spines. It is uncommon in the UK but much more abundant in southern Europe.

Fallen oak trunks and large branches are particularly good places to try to find this pale ochre or pinkish crust-cum-bracket species, which has been 'parked' in its present position in the taxonomy of fungi - hence the term 'insertae sedis' mentioned in the taxonomic classification above.

The specimen shown here is young and pale; with age the central part of the fruitbody usually turns more intensely ochre.
