Hello,

On the same branch as mentioned in my topic "Chaetosphaeria?" 05-03-2018, hidden under the moss.
Not the anamorph I was looking for ....

Found by a friend (March 2018, Netherlands).
Spores 1-3 septate, 41.8-50.0 x 4.6-5.0 µm.
Hilberina?

Re : Hilberina?

Lasiosphaeris hirsuta, which is suppose to have hyaline, aseptate ascospores, but they can become pale brown and septate at times. This species represents a complex of several cryptic species with similar morphology.

Re : Hilberina?

Hi,
I sometimes find a very similar fungus that I call Hilberina moseri, but with reservations because this species is not well-documented. The microscopic structure of the ascomatal wall would be helpful for comparison with similar species.
Best,
jacques

Riet van Oosten, 08-03-2018 18:20

Re : Hilberina?

Dear Andrew and Jacques,

Thank you very much for your help and explanation!
I had only two ascocarps, no material left.

Best wishes,
Riet

Re : Hilberina? => Lasiosphaeris hirsuta

Hi Riet,

I agree with Jacques.
Can you be more specific about the substrate?

Bernard

Andrew N. Miller, 09-03-2018 15:37

Re : Hilberina? => Lasiosphaeris hirsuta

Dear Riet,

It looks like you have ample material. Would you be willing to send me the specimen so I can sequence it from the ascomata? DNA will tell us what this is... ;o)

Cheers,
Andy

Re : Hilberina? => Lasiosphaeris hirsuta

Dear Bernard and Andrew,

Hopefully my friend will tell me soon more about the substrate.
I'm so sorry, I had only 2 ascocarps of this species ...., they were hidden under the mosses.

Best regards,
Riet

Re : Hilberina? Lasiosphaeris hirsuta?

Just got a message, the substrate is poplar (dead wood).

Andrew N. Miller, 09-03-2018 23:01

Re : Hilberina? Lasiosphaeris hirsuta?

Then, this is probably H. moseri. L. hirsuta grows in great abundance. What are the other black dots to the left of the moss in the first photo?

Re : Hilberina? Lasiosphaeris hirsuta?

Great news!
Thank you all for your help!

Tried to make pictures of the microscopic structure of the ascomatal wall .....
