Hello,

Found by a mushroomfriend on Urtica. He gave me a name: Macroconia leptosphaeriae.

Could this be this species? Anamorph and teleomorph? I haven't seen asci ....

Spores : 17.7-17.9-21.5-22.0-22.7 x 6.9-7.2-7.2-7.3-7.3 µm

Conidia: 49.6-60.7-66.5-72.3 x 5.7-6.3-6.8-7.0 µm

Greetings, Riet

The black one, orange one, or both?

Re : Nectria on Urtica, anamorph and teleomorph

the red one -

the black one should be the substrate - old Leptosphaeria acuta`(?)

Best, Lothar

Re : Nectria on Urtica, anamorph and teleomorph

Thanks, Lothar - I suspected the black one was the substrate (and not Urtica).

Re : Nectria on Urtica, anamorph and teleomorph

No, this is Leptosphaeria doliolum, it have concentric-conical pseudothecia.

Re : Nectria on Urtica, anamorph and teleomorph

Found the emails for the replies in my spambox, therefore my late respons.

Thank you very much for your confirmation and the information Patrik!

It was difficult to see but I thought the conidia came out of the black ones...
So I was wrong.

Re : Nectria on Urtica, anamorph and teleomorph

Hi all,

The anamorph of a Leptosphaeria would be Phoma-like, conidia's included.

Cheers - LUC.
