Ramsbottomia asperior possibilty
Hardware Tony, 28-05-2020 11:45
Hardware TonyFound this hairless orange operculate fungi largest around 2mm on damp soil near a river close to Salix. The spores obviously led me to this species but a few contentious sps had to be checked. I tried to check the spines off the spores and the majority were less than 2µm, few slightly larger. The spores within the asci suggested slighly subglobose shaping rather than spherical so came to the conclusion that this probably was R. asperior. First for Cornwall where I survey, with just two other in SW England. If anything esle would be even rarer.

With thanks for your opinion based on the images I can provided here.

Re : Ramsbottomia asperior possibilty
Hello Tony,

Yes, I believe that you are right. Ramsbottomia asperior has the shorter spines on its fully mature spores, as you illustrate in your 1st image.

The orange, granular pigment in the paraphyses shows on your 4th image - again correct for this species.

It grows on bare soil in wet places such as banks of rivers, so the environment is spot on too.

If you have a copy of my book, I published 178 additional species pages along with host index tables which are available free of charge, if wanted. 

With Best Wishes,
Peter.

Re : Ramsbottomia asperior possibilty
It would be interesting to genetically compare your collection with the collections made in Alpine zone (at high elevation). Can you send to me a part of the collection?
