Sarcoscypha? or Pezizale
Zuidland Peter, 02-06-2021 05:15
Hi
This the first year with a microscope to look at this white ascocarp that I see each year in one location. It starts as a cup and gets to 4-5cm and flattens out, it is always on small pieces of wood amongst litter in a wet, Cool Temperate Eucalyptus forest, solitary and bunching.
Asci: 310-360um, -ve MLZ, rounded base =-ve crozier, apical operculum
Spores: 24.3-29.5 x 10.0-11.4um, 2-3LB's 3.5-6.7um, most have blunted ends with indent, some with envelope.
Paraphyses: 1.5-3um, filiform, small droplets towards apex, septate and LBs
From the ID key it looks close to S.jurana to me but this seems unlikely with no history of it in this country. 
I hope someone can help.

Many thanks

Peter

Re : Sarcoscypha? or Pezizale
Hi Peter

This looks indeed like a Sarcoscypha. The undulating ascus stalk seemingly without croziers and the thickened operculum are diagnostic, also the proismatic ectal excipulum. I remember a S. vassiljevae with white apothecia if I am not wrong.

I assume the country is Australia or New Zealand?

Re : Sarcoscypha? or Pezizale
Many thanks Zotto and yes I am in Australia, more spefically Sth Gippsland, Victoria, which has a cool temperate climate.
I made a mistake with my first try which did have the location details but forgot the next time sorry.
There were not many images when I googled for white Sarcoscypha, I will try to look for info on S. vassiljevae; is it possible for it to live in a cool climate, albeit with some hot summer days of 40c+?

Re : Sarcoscypha? or Pezizale
From GBIF: Sarcoscypha vassiljevae is indeed white and finds are in Russia and Japan, cool climate may not be an issue.

In my old homepage


I have a survey on the species, with this note:

Sarcoscypha vassiljevae Raitv. 1964, Eesti NSV Tead. Akad. Toim. (Biol.) 13:29 - From Wladiwostok. Apothecia with constantly white hymenium, spores 21-29 x 10-13 µm.

What mounting medium did you use? It seems to me lethal to cells, or you took the dry sample in water.
Zuidland Peter, 02-06-2021 09:13
Re : Sarcoscypha? or Pezizale
Sampled over a few days and it did dry out, most mounts were in KOH but some in water.
I have looked at the link you provided and I am keen to get fresh material after reading the importance of it with this genus, it is not far away from home.

Re : Sarcoscypha? or Pezizale
Yes, vital studies are essential in discomycetes. For S. vassiljevae there is no vital study known to me, regrettably, but two ITS sequences exist in GenBank.
