Kretzschmaria on birch & grey alder

[DC0725]

Seen today at a clients property. The area around the trees was cleared using a mini-digger a few years ago, which may have resulted in some root damage leading to colonisation. The alder is also in decline from Phytophthora alni.

 

Shows again that the fungi don't always stick to the hosts listed in the text books.

Well spotted, particularly on the birch. Never come across kd on birch before, but I imagine it would make pretty short work of it...

Nasty!

 

Not seen it on either myself, presumably you have advised removal?

Yeh recommended fell. I can't imagine birch has much capacity to compartmentalise against it and there seems to be a general consensus that once fruiting bodies become visible decay is normally fairly advanced.

 

Its the first year its fruited on the alder, as I visited to take a look at that last year and it wasn't visible. Went back to price felling the alder and some ash today and spotted it, then tucked away behind some grass on the birch too. Will be putting 5 day notice in this week
