Eutypa species perhaps?
Hardware Tony, 27-06-2020 13:21
Hardware TonyI wondered if anyone could help me with this ascomycete, looking very much like Eutypa but all known lit references do not get close to the spore size or macro appearance. 

Found on dead Prunus twig in litter in a supermarket car park!, details are:
Spores 12 - 14.83µm x 2.25, 2-guttulate, Allantoid thick walled, slightly verruculose. Asci large extended 50 -65µm, with centrally stacked seriate spores, no colour change. Paraphyses translucent and guttulate, if that is what they are, Bck stroma 0.3mm high with sometimes large horizontal browning topped slits with apparent closed aperatures on the side, Fruit bodies not embedded.  Ignore white strands seen occasionally, left over from tissue while wetting - still learning!  Nearest I could get to:  E. scabrosa.

Many thanks  Tony Hardware

Re : Eutypa species perhaps?
This is another group of fungi that it is wise to ignore unless you get desperate...

Species delimitation is poorly understood, and the genera are mostly not real either. Rappaz's world monograph (1987) recogizes a large number of species, but many of them are separated by rather minor characters and the group has not been sufficiently tested using molecular methods.

Your specimen is problematic as it occurs on narrow twigs, so the stroma characteristics may not have developed fully. Most likely this is a species of Eutypella, perhaps E. leprosa which has been reported from Prunus. However, best to record it as Eutypella sp. unless someone else knows better.

Re : Eutypa species perhaps?
Hi Paul,
Many thanks for this advice and best way forward.  I'll certainly take this into account in future. 

Maybe this applies to other genera such as Anthostomella as recently found on Miscanthus sinensis (Chinese Silvergrass) in the back garden! but all species in Ellis and elsewhere do not match the spore size and type. 

Best regards   Tony

Re : Eutypa species perhaps?
No, Anthostomella species are usually manageable, though it's a possibility that yours could have been introduced as an endophyte with the plant. Not sure whether it should really be accessible on Ascofrance, but the link below is the most useful start for the genus...


Good luck...
