Teeth on underside

Add a sighting Subscribe View significant View unverified

The fruitbody of a fungus in this sub-group has teeth or spines on the underside. The teeth or spines are of uniform size and shape. If you see teeth of varied shapes check the pored/maze-like species of the previous sub-group.

The fruitbodies of Pseudohydnum, grey on top and with white teeth below, have a jelly-like consistency.

Warning

In dry conditions Pseudohydnum fruitbodies may lose their jelly-like nature and feel quite firm.

Sometimes you may need to use a magnifying glass or handlens to check whether you have a fruitbody with densely-packed teeth or one with tiny pores.

Not sure about the type of wood. Possibly BlackButt.

Greenish tints are from algal growth.
The upper surface appears to have been densely hairy prior to algal invasion.
Are they really 'teeth' or is it just the hymenophore breaking down with age?
Did you note the type of wood it was growing on?
