Fusarium on Hibiscus

In my garden two shrubs of Hibiscus (15 to 20 years old) did not survive the winter season. Today I observed lots of orange dots down to the roots that turned out to be conidiocarps of a Fusarium species. The last service I try to give to these beloved flowers is to give their hangman a name. ;-)I attache some pictures, but the host will be certainly more helpful for determination, for those who know....
Typical conidia show 3 septa but 0-4 septa were observed as well.
Best regards
Martin

Re : Fusarium on Hibiscus
hello Martin
others with greater knowledge may contradict me, but my experience is that Fusarium is a 'culture or sequence' genus - easy to recognise at the generic level but impossible to name on macroscopic and microscopic information of field characters alone, unfortunately

Re : Fusarium on Hibiscus
Hi Martin & Chris
I made the same experience :-(
http://www.ascofrance.fr/search_forum/11579?
But you have the opportunity to await the teleomorph if any exists. Or did you remove the shrubs?
We have here also Hibiscus shrubs in gardens which look rather ill. I will have a look.
Are these Fusarium species really polyphagous? Or does the host help in the identification?

Re : Fusarium on Hibiscus
Hi Martin,
I would like to study and sequence your Fusarium, could you please to send me a part of your collection?
a lot of thanks

Re : Fusarium on Hibiscus
Dear all,
here are molecular data of Fusarium on Hibiscus, no doubt, that is Gibberella pulicaris.
All my best

Re : Fusarium on Hibiscus
Dear Christian,
thank you very much for your efforts!
I have but a problem with your result. When I run a BLAST at GenBank with your sequence CLL12012_ITS4 the best match showing up is F. merismoides (not even fitting macroscopically to my find).
Is this due to the fact you choose ITS4 (no entry for Fusarium at GenBank features it) I cant't comprehend your result? I have to learn very much in this field!
curiously,
Martin

Re : Fusarium on Hibiscus
Dear Christian,
attached an alternative tree. I added the well matching F. merismoides and the common F. oxysporum. The outgroup Microdochium nivale I choose following Watanabe et al. 2011.

Re : Fusarium on Hibiscus
Sorry dear Martin,
I made a mistake about sequence, the one I have posted is not from your specimen but it is a Dialonectriaa.
I attach the correct sequence.
excuse me,
Regards,
Christian

Re : Fusarium on Hibiscus
Thank you Christian,
that explains a lot! So the name of my Hibiscus killer will be Fusarium sambucinum... ;-)
No, I learned meanwhile that last winter many shrubs died due to frost and those Fusarium fungi just entered the dead or dying plants.
