Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
It helps when trying to identify the different Punctelia's to check the under surface of the lobes and the C reaction of the medulla (inner layer)
The under surfaces of P. subrudecta lobes are lightish-brown or whitish, darker-brown at the centre.
Medulla and soredia: KC+ red, C+ carmine-red
Your input is greatly appreciated. I'll remember to check the undersides next time I visit this area. I haven't progressed to chemical testing yet, but no doubt my enthusiasm will soon demand it!
