David,
 

1) I forgot to comment on Fomitopsis pinicola. Its apparent absence as a 
native of the UK is interesting, since we might have expected it to occur on 
Pinus sylvestris, at least in Scotland. One of my colleagues found it growing 
on a fence-post in his garden in the 1990s, but the timber had probably been 
imported. Like you, I have seen it on broadleaved hosts such as beech on the 
continent; for example in Germany.
2) Is the spelling correct in the Dutch-language definition of "necrotoof"? 
In my ignorance as a non-Dutch speaker, I would have guessed that it should 
be spelt with an "r": "necrotroof".


1) As airborne spores won't normally travel much farther from the source than 
about 300 kilometres while still having a pretty good chance of "hitting" a 
suitable (living) substrate, I would not expect F. pinicola to appear first 
in Scotland on pine after crossing the North Sea, but arriving on beech or 
birch in the southern parts of the U.K. from Belgium or France after crossing 
the Channel.
2) Necrotroof is correct. By the way, the Dutch list says, that the term 
facultative parasitic is mainly used in England and not on the continent. How 
about some international coherence in using these terms ?

Kind regards,
Gerrit
 

Dear David,

I use the definitions from this list (in Dutch) ( 
www.springerlink.com/content/tuj653216XXXXXXX ) and to add some more 
information on the subject of tree species specific strategies of parasitic 
macrofungi being part of and co-evolved within a tree species specific 
ecosystem (Keizer, 2007/2011), the following on the tree species colonised by 
Fomitopsis pinicola on the European continent.

Originally Fomitopsis pinicola was only found on coniferous trees, mostly 
on Picea and Pinus. In 1982, I found it on a Betula trunk in a spruce 
forest invested with F. pinicola in Luxemburg. Some years later, I 
documented F. pinicola from old beeches in Luxemburg and Belgium and later 
on also in Germany (Eifel). In Poland it is mainly found on roadside Acer, 
on which I also found it this year along a riverside in Austria (see : 
http://arbtalk.co.uk/forum/490816-post37.html ). In Sweden, where it is 
common on coniferous trees, and Germany (Bavaria), I found it on Prunus.
In The Netherlands, it first was found on Picea and nowadays it is mostly 
on Betula and Fagus and twice on Quercus robur. As Laetiporus sulphureus 
has not (yet) been documented from beech in The Netherlands, F. pinicola, 
apart from some saprotrophic Coniophora species, is the only macrofungus 
causing brown rot in Fagus.

So I wonder what tree species F. pinicola will use as first and secondary 
"stepping stones" once it starts invading the U.K. (entirely).

Regards,
Gerrit
