Fungi that bite ...

Velvet Tooth (Hydnellum spongiosipes)

H. spongiosipes (Thelephorales: Bankeraceae) is an uncommon stipitate hydnoid fungus. These are a group of ‘tooth fungi’ [fungi that release their spores from tooth-like structures], which have a short stalk or 'stipe', hence the name 'stipitate'.

Stipitate hydnoid fungi are ectomycorrhizal; forming close symbiotic relationships with trees and deriving some of their nutrients from the tree's roots. This aids them in obtaining nutrients where soil quality is poor and means they are always found in association with trees. H. spongiosipes is typically associated with oak, sweet chestnut and, less frequently, beech; this provides a useful, but not necessarily accurate way of distinguishing between this species and H. ferrugineum, which occurs mainly under pine.
