Jim Ginns’ comments of August 24, 2013:
Here is my key to Porodaedalea species in BC:
1a Context up to 4 mm thick, setae mostly 7-10 µm diameter, skeletal hyphae
2-4 µm diameter P. chrysoloma
1b Context up to 3 cm thick, setae mostly 10-14 µm diameter, skeletal hyphae
3.5-7.5 µm diameter P. pini
Your photos show clustered, imbricate conks that habit is more typical of P. chrysoloma. The setae up to 65 µm is typical of P. chrysoloma. Setae in P. pini up to 50 µm. The setae as narrow as 7 µm is typical of P. chrysoloma. Setae in P. pini as narrow as 10 µm.
The narrow hyphae, 2-3.5 µm diameter is typical of P. chrysoloma. Hyphae in P. pini 3.5 – 7.5 µm diameter.
I’d say you have P. chrysoloma.
Cheers, Jim

We will ask Jim Ginns
