Re : Octospora sp. ???

Hi Yasin,


this looks quite interesting. The micros lead best to O. rustica but this grows with Ceratodon purpureus. On your picture I see a Fissidens spec. and a cf. Polytrichum spec. - but the known Octosporas growing with such mosses are different.


Best regards, Lothar

Re : Octospora sp. ???
Avec des spores si petites, on ne peut en effet penser qu'à Octospora rustica. Il doit y avoir d'autres mousses que celles qu'on aperçoit sur la photo.

Re : Octospora sp. ???

... I have to correct myself: the Polytrichaceae surely is a Pogonatum species (aloides or nanum) as there is a distinct permanent protonema present (green layer on the ground) - I overlooked this at first glance.


Anyway - no substrate for O. rustica.


Best regards from Lothar

Hello Yasin,


today Torsten Richter wrote me via e-mail that he would like to have a look at your Octospora (fresh carpophores). He says (like me and Gilbert) that it cannot be rustica with the mosses on the picture. His address:


Torsten Richter - Forstweg 26 - 19217 Rehna - Germany


Best regards from Lothar

Re : Octospora sp. ???
Dear Uzun Yasin,
it is probably a Octospora close to O. humosa. Unpublished data suggest, that there are several closely related taxa around humosa on different species of Polytrichaceae (i.e. Atrichum, Oligotrichum, Pogonatum). You can file your collection under 'O. humosa s.l. (Pogonatum)'. Please try to identify the moss. It is very important in Octospora.
With best wishes
Jan

Re : Octospora sp. ???
Thank you Lothar Krieglsteiner; Gilbert MOYNE and Jan Eckstein for your help.

Dear Jan Eckstein; I know your web site the octospora.de. and I fallow and read your articles about bryoparasitic Pezizales from researchgate, jstor and the other databases.

I will try to get new microscopic pictures and share with you.

Should I use cotton blue or Lactophenol cotton blue or another chemical for this specimen ??? I think the ascospores have some ornamentation.
