[Dean Lofthouse]

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!)

Thanks Tony...

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

...this bit I understood!

 

Just out of interesst what does the (Hoffm.) bit refer to?

[Amelanchier]

It refers to Hoffman, another Taxonomist who I believe determined the "deusta" epithet, meaning "burnt" in greek/latin...

[Bundle 2]

It is a bit of a nonsense when it gets so involved...although I understand your comments Tony vis a vis dna whu. Linnaeus devised the latin in family, genus, species cultivar as an universal system ( nomenclature ) to keep it simple.....
