Phellinus tuberculosus

[David Humphries]

David,

Nice documentation . Do you know whether the brackets close to the cut were there before or appeared after the tree was felled ? Both ways, it seems like an example of panic fruiting with as much fb's as possible.

 

 

No idea Gerrit, just glimpsed on driving past it in a very rural hamlet in Suffolk.

 

Never been there before, or likely to go back

Looks and acts a lot like Phellinus spiculosis, which has its way with some Carya spp. here.

Gorgeous images thank you!

To make sure.. is Phellinus tuberculosus the same as pomaceus?

 

How and why are these cankers formed from Phellinus Gerrit?

What research has proven your claimed similarities between the living and dead wood invading and degrading strategy of the non-European Phellinus spiculosis fruiting from Carya and that of the European P. tuberculosis exclusively fruiting from Prunus ?

1. is Phellinus tuberculosus the same as pomaceus?

2. How and why are these cankers formed from Phellinus ?

 

Nick,

1. Yes.

2. How : by invading the living tissues with hyphae secreting mycotoxins. Why : with fungi, the answer to a why question almost always is to get to the energy sources.

by mycotoxins I presume this is produe by the fungi in order to supres growth of competing mycos? as I understand it oudemansiella mucida has similar properties, that have been copied to produce a anti fungal crop spray/dusting?

No, mycotoxins are produced to alter (canker) and/or kill living tissues of plants or trees and for killing nematodes, self produced fungicides are used to suppress the growth of competing fungi.

So a mycotoxin is a toxic substance produced by a fungi? And a fungicide obviously is a substance toxic to fungi, so some fungi eg O. mucida, produce 'fungicidal mycotoxins'?

Just observations: not for publishing, beyond a forum post! I did read a very nice dissertation on spiculosis though; cited. Do I get points for that?

They are both biotrophic and parasitic, slowly killing their (yes, different) hosts. Appearance of heart rot and basal branch decay looks similar from here. P. spiculosis smelled like hay--how about P tuberculosis?

 

Ascribing a "why" to plant or other non-human behavior almost seems like teleology.
