Parasite on Leotia lubrica
Bernard Declercq, 18-10-2017 12:25
Bernard Declercq

Hi,


Can anyone help me to identify this parasite on Leotia lubrica?


Conidia spherical, 15-20 µm diam., thick-walLed, with mucous coating. I presume that this coating will result in some ornamentation.


Thanks in advance.


Bernard

Re : Parasite on Leotia lubrica

looks like (the anamorph of) Hypomyces leotiarum.


Best regards, Lothar

Re : Parasite on Leotia lubrica
Hi Bernard and Lothar,

Indeed, Hypomyces leotiicola.
On August  16th 2017 I also found Leotia lubrica, some of these frb's were mummified which I took home for research. Here are some photos of conidiophores, conidia and aleuriospores


Warm regards

François Bartholomeeusen

Re : Parasite on Leotia lubrica

Hello Francois,


leotiarum or leotiicola - wll, I just looked in Index of Fungi.


Here I find:


H. leotiarum Fayod (I used this name by now), now Sepedonium leotiicola


H. leotiicola Rogerson & Samuels, with this name being actual ...


I am a little bit confused - are there two different species? If yes, o.k., then I used the wrong name by now - all what I found is the fungus of this thread.


But if not - why a new name? Is Fayods name illegitimate?


Best regards, Lothar

Re : Parasite on Leotia lubrica
Dear Lothar, 

Honestly, I'm an amateur mycologist and anamorphs are not my thing. I supported my determination on the key in the Study of Clark T. Rogerson and Gary J. Samuels: Species of Hypomyces and Nectria occuring on discomyctes in Mycologia vol. 77 No. 5 p. 763-783.


I hereby send you some sprintscreens with more explanation.
Have I made a fool of myself or is my conclusion nevertheless correct,
Would you be so kind as to look in to that?
Thanks in advance,

François

Re : Parasite on Leotia lubrica

Hello Francois,


thank you very much for the file.


I am not convinced and would call the species H. leotiarum what is the earlier name. As it is considered conspecific with the new species, I do not see why the new name is necessary. Maybe it was, but now we have the equality of anamorphous and teleomorphous names ..


Or am I wrong?


Apropos: I would be interested in the whole paper - if somebody has?


Best regards, Lothar

Re : Parasite on Leotia lubrica
To whom it may concern: Correction of my intervention of 18/10/2018

After measurement of the conidia (5.5-8.1 x 2.49-3.6 µm) and aleuoriospores (10.7 – 13.4 µm) I must conclude that my determination was incorrect.

Either, the mummified Leotia lubrica was not the host or my preparation was contaminated by Hypomyces cervinigenus which I also researched the same day.
Please accept my apologies for my hasty response.

Best regards,
François Bartholomeeusen
