Victoria Beach
bracket fungus
F P Ralston

Several species of Steccherinum are listed in the Manitoba & Saskatchewan list from Bisby et al. Any good resources to distinguish (i.e. available keys)?

Two more sticks are included that seem to be covered with something else (posted as separate observation, but see pic).

The above-mentioned extra two sticks pic never showed up with the original observation post. They are apparently something else anyway. See:

Teeth versus pores

Steccherinum is a toothed fungus. The teeth are all separate and rounded. A hand lens helps to see this. There are several polypores like Irpex and Trichaptum where the pores grow out jagged and look toothy. But if you look carefully straight into that lower surface you’ll see that the “teeth” are flat and joined together at the base into a pore or irregular pore pattern.

For future reference, how can I distinguish Irpex lacteus from Steccherinum?

Irpex lacteus is a common polypore with toothy jagged pores.
