Summary: Phellinus ribis attacks (Osage orange) stemwood exposed in wounds.

http://www.na.fs.fed.us/...
“Maclura pomifera (Raf.) Schneid. Osage-Orange …

Irene — you found the same reference that I did. Does Poria also turn black with KOH? And does it develop layers like this? Also, this quote mentions the other two occur only on dead wood, and P. ribis in wounds (as this was.)
