Possible Peziza polaripapulata
John Leach, 28-05-2015 19:45

Hi all


I recently found this Ascomycete in Anston Stones Wood growing on the underside of a very wet 'rotting' Fraxinus log.
The Spores measured 17 x 8 microns. Ascus tips blue in Melzers,


Any help, comments much appreciated as always.


Best Wishes - John

Re : Possible Peziza polaripapulata

Hello,


 


very probably yes.


The colour change (olivaceous to ochraceous) and the shape (somewhat umbilicate) are typical for the "apiculati"-group. But to be certain we need to see mature spores and how the ornamentation looks like then. Best coloured by cotton blue.


best regards,


Andreas

Re : Possible Peziza polaripapulata

Hello


Sorry for the delay in reply but I needed to get more material. Even after a thorough search I only managed to find another 2 small Apothica 8 to 11mm dia.


I did as you suggested but still can't replicate the spore characteristic as in your images. Maybe I did not soak in CB for long enough. Should I leave longer perhaps?

Re : Possible Peziza polaripapulata

Hello John,


the two apothecia shown are very likely to be too young to have mature spores. The characteristic ornamentation is only to bee seen at really mature spores.


best regards,


Andreas

Re : Possible Peziza polaripapulata

Hello Andreas.


Yes I think I only have very young material as you suggest. I'll keep an eye on the 'log' for any further development but will name the fungus cf Peziza polaripapulata for now.


Thanks again for all your help.


Best Wishes - John
