Setose Perithecia
Charles Aron, 27-03-2024 22:53
Charles AronHi All,

Recently I came across these minute, setose brownish perithecia on dead stems of Hemerocalis (Day Lily). The Fbs are c0.1mm with well speced setae (60-110x7-25). The setae consist of bundles of thick-walled hyphae. Ascospores are hyaline and septate with four guttules, smooth or with a very slightly uneven outline (14-16x4-4.5). The ascus walls are very difficult to discern, especially in mature aci. Negative reaction in Melzer's.  

I'd be grateful for any information on this fascinating little fungus. 

Best regards, 

Charles.

Re : Setose Perithecia
Hi Charles,
Have you considered Helminthosphaeria? Maybe even H. triseptata as spores fit very well but not the setae. Good description at:
https://fungi.myspecies.info/all-fungi/helminthosphaeria-triseptata

Seems like variable septa.
Others could be H. corticiorum.
regards  Tony

Re : Setose Perithecia
Hi Tony, 

Many thanks for your suggestion-Paul's website is a good resource! I think, however, that we are looking at a Nectria relative but what genus, I'm unsure. Amazing what you can find while gardening-I'm sure lots of mycologists agree!

Best wishes, 

Charles.
