ID help please

[Arob]

Apologies for the poor pictures (camera phone, the 7 sided object is a 20p piece).

Discovered these hidden at the base of a large lime today, found a cavity hidden by epicormics and area above sounded dodgy, then spotted smaller fruiting body.

Investigation of the cavity (it went horizontally into tree and into ground too) then turned up another small fruiting body but also some very unusual looking black 'sheets', very angular as if a pressed man made material, one piece had some mycellium and small white mushrooms.

Any suggestions?

 

Thanks.

Now id'd as ustulina deusta.

[Steve Bullman]

not to be picky, but for future reference its actually been renamed to Kretzschmaria deusta

[benedmonds]

Apparenty the renaiming is not set in stone and the people who renamed it are saying you can use either??

[Steve Bullman]

that makes it even more stupid

[Arob]

Thanks for the info Steve, all good advice gratefully received - I'll make sure I log it twice.

Any idea on the black sheet structures? I'm going to have to see if I can read up on that.

Doesnt it....

The naming of organisms used to be done by anatomical analysis. So organisms that shared similar structures / organs / environments would be grouped together.

These days, DNA or RNA analysis allows organisms to be grouped by actual genetic similarity rather than anatomy.

 

Ustulina deusta was reclassified by taxonomists after genetic analysis in a paper submitted to a peer reviewed journal, in which it was decided that the fungi belonged in a seperate genus to Ustulina. (incidentally which a previous taxonomist had proposed in 1970!!) However, that doesn't necessarily mean that other taxonomists accept the reclassification...

 

We tend to call multiple names for the same organism Synonyms. So its possible to refer to either Ustulina or Kretszchmaria in common use but in technical use you should refer to the person who named it.

 

Which would be Kretzschmaria deusta (Hoffm.) Martin or Ustulina deusta (Hoffm.) Lind

 

And just in case you want to use some of its other names... (courtesy of wikipedia!)

Sorry almost forgot. Thats very bad news for your Lime Arob. Particulary intense decay on that host.
