Fungus on herbaceous
Lepista Zacarias, 08-03-2017 01:21
Hi again,
This fungus was growing on the stem of an herbaceous plant. I tryed to observe it under the scope, but I was not able to find any reproductive structure. Any hint about what it can be?
Thanks in advance,
zaca

Hi Zaca,


macroscopically, this looks like a Lophodermium, for instance.


But without ripe structures I am not sure.


Best regards, Lothar

Thanks, Lothar.
I had no idea of what type of fungi can have such appearance. Certainly Lophodermium is an hypothesis.
Kind regards,

Hi Zaca,
yes, this can be Lophodermium, but also Hypoderma, Lirula, Meloderma....

One mup the substrate keep damp to get the fruit layer, while the perithecium open lip-shaped. There it depends on the spores form and spores size, the form of the paraphyses, the exact substrate....
D. W. Minter had got a very good work in the net, unfortunately no longer there. At that time it had tempted me into this imagination.
Greetings Peter

Hi Peter,
Marvelous photos you show us, including that with the cover of the book where you participated.
I'll be more attentive in the observation of this type of fungi.
Best wishes,
zaca
