Lasiobolus
Malcolm Greaves, 11-12-2015 01:45
Malcolm  GreavesThis "Lasiobolus" was on rabbit dung. Pale cream 0.15mm across with thick walled septate pointed hairs 110µ long. The spores were 17.5 x 10.5 and smooth.
From what I can see Lasiobolus have non-septate hairs so could someone tell me where I should be looking.
Thanks
Mal

Re : Lasiobolus
Hi Malcolm,
these are too few data to determine the species. The shape and size of the Asci are necessary here at all costs. Nevertheless the L. intermedius could be.
Greetings Peter.

Re : Lasiobolus
Thanks Peter. There is another spcimen growing I will try and get better information from that.

Re : Lasiobolus
Hello Malcolm.

I think your fungus is not mature enough; I seem to discern in the pictures a reddish tint. Also, the hairs Lasiobolus species are normally non-septate.

Re : Lasiobolus
Nice find, Malcolm!

As Michel said, with septate hairs, this is not a Lasiobolus.
In my opinion this should be Trichobolus dextrinoideosetosus Doveri.
One of the 8-spored species of the genus.

You'll find it here (page 511ff)
http://mycosphere.org/pdfs/MC3_4_No13.pdf

I found this species 11 times in Germany. All on dung of rabbit and hare.
You can compare with my documentation at Pilzforum.eu. There are also some great pictures by Björn Wergen.

Re : Lasiobolus
Hi Norbert.

I had actually thought about Trichobolus, but not to this species that I have never met; yet I have the paper F.Doveri ..... !! Beautiful pictures of Björn !! Thank you .

Regards.

Michel.

Re : Lasiobolus
Thanks for the information and link Norbert. With more photos and details Trichobolus dextrinoideosetosus is a very good match. The septate thick walled hairs are certainly dextrinoid and some have a root like base. The asci are clavate 100-120 x 30-34. The paraphyses simple slightly bent towards the apex. Is there anything else that I should check before claiming this species?
Thanks
Mal
