I’m not certain what you mean by that, Adolf. I’m not identifying anything. I became interested in this record because I was not familiar with the name, not because of any observations affiliated with it.
You have to work on identification first and Index Fungorum would not help you too much. You have to work on the taxonomy first. My search on Google Scholar gave me this article that deal with Phoma:
That was after a really quick search. You have to start somewhere there.
Paul Kirk, and the other kindly contributors at IF, the majority of the older material is usually available at librifungorum. I literally cannot imagine what doing this was like prior to the Internet!
It all adds up. Thanks for the additional context, Adolf and Oluna. I’m still interested in learning about the concept of Sphaeria, which was discarded. MO may not be a good platform for solving nomenclatural issues, but it is an excellent medium for communicating about said issues.
The International Code of Nomenclature (Melbourne Code) does not allow dual names for fungi with pleomorphic history. In this particular case, Leptosphaeria acuta was the name for the telemorph and Phoma acuta was the name for the anamorph.
Article 59 of the Code tells you how to deal with this problem:
I think that MO is not a good platform for solving complex nomenclatural problems and the MO name should follow Index/Species Fungorum.
IF ascribes the basionym to Fuckel, who published Pleospora acuta in 1870.
MB ascribes the basionym to Mougeot & Nestler, who published Sphaeria acuta in 1826; both resources acknowledge that Mougeot & Nestler’s publication was invalid, which doubtless relates to how IF cites the name. And on top of it all, there is a Sphaeria acuta published by Hoffman, in 1778 that IF lists as a synonym for Leptosphaeria acuta, but MB lists as a synonym for Phoma acuta!
There is a bit of an unsolved puzzle here, I think.
