Cordyceps
Malcolm Greaves, 04-07-2013 12:32
Malcolm GreavesThis Cordyceps was growing from a fly which should make it Cordyceps forquignoniiC but the only information I have says that the "head" should be 1-2 mm and globose.
Cordyceps sphecocephalaon the other had should be 3-6 x 1.5-3 mm but on wasp.
This specimen was 4 x 3 mm
What should I look for to distinguish the species?

Thanks
Mal

Re : Cordyceps
Thanks for the guidance. With the size and shape of the head C sphecocephala looks the right result although I see that all records under this name on the FRDBI have been moved to C ditmarii.

Re : Cordyceps
Hi Mal
note the passage in the document to which Christian has provided the link:
"Littérature : on trouve cette espèce sous le nom de C. dittmari, C. sphecocephala f. ditmarii (=ditmari), C. sphecophila, ou C. sphecocephala (Les récoltes européennes doivent être rapportées à Ophiocordyceps ditmari)." (my underlining - I think the problem is that some of the other names have been variously interpreted in the past).
cheers
Chris

Hi Malcolm.

It is certainly Ophiocordycerps ditmari. I have attached two photos taken by a friend a week ago.

Regards.

Michel.

Re : Cordyceps

Hi to all,


Traditionally, the specimens collected on wasps were named C. sphecocephala or O. ditmari and the specimens on flies C. forquignonii. We have studied both specimens, cultures and molecular data indicate that they are the same species.


Cordyceps forquignonii Quelet has never been collected since the publication and nobody really knows what it is. Holotype disappeared and we have only an illustration, which contains numerous incoherences.


 


Regards,


Christian
