Orbilia on Tilia
Charles Aron, 18-03-2024 22:12
Charles AronHi All, 

Another dessication-tolerant Orbilia, this time about 2m up on an attached branch of Tilia. The curved ascospores are similar to curvatispora but at 7-10xc1 seem a bit shorter and wider. Asci are 26-30x3 and glued together with an epithecium. The paraphyses are constricted apically. 

I'd be grateful for any suggestions. 

Charles.

Re : Orbilia on Tilia
Hmm, this looks interesting!

The paraphyses are apically lanceolate which is rare in the O. auricolor group to which I would assign this species. But who knows! Helpful would be to study the margin. Are there hairs or glassy processes? A view on the exterior or a section would clarify also the presence of hair-like cell rows there.

I would need to try my key in the monograph, startig with section Arthrobotrys, I cannot remember a match.

In which region did you collect this?

O. curvatispora is a synonym of O. auricolor (which is a collective species).

Hi Zotto, 

Thanks for your views on this. Here is another photo of the excipulum which may shed some light. The material was collected on Anglesey, North Wales. When I'm next in the locality I'll look out for more. Only found 2 apothecia. 

Best wishes, 

Charles.

A bit unsharp but it shows either exudate or short glassy processes.

The only species with lanceolate paraphyses I have in mind are O. jesu-laurae and O. blumenaviensis, but I thnínk both can safely be excluded.

Hi Zotto, 

Very interesting. Likely to be an undescribed species? I'll look out for more material. 

Best wishes, 

Charles.
