Fungi on willow

[jacquemontii]

Just spotted this delightful fungi on a willow. I think it could be Phellinus robustus??

[Andrew Gale]

Phellinus robustus tends to be associated with Oaks a bit more although can be found on a host of broadleaves; I'd be more inclined to go for Pehliinus ignarius, host tree is willow.

Looks like fairly young Phellinus igniarius

Always start with species specifics, as the guys before stated, P. robustus is an Oak fungus, whereas this is on willow, and would be 100% P. igniarius without spore evaluation under a microscope.

 

The host lights the way, the fungal genus can be worked out easily, the genus of host and fungi is the guiding foundation, only overruled by Microscopic evaluation thereafter
