Another Helotiales - from Salzburg Austria
S. Rebecca, 05-11-2023 20:53
Here is a Helotiale fungi found at Werfen/Salzburg Austria on a playground maintained by the town. It was next to a concrete bench on the ground in grasses. Some of the soil that I took with me showed a massive net of fine roots and one little piece of a seed. I looked for sclerotians but did not find any. It was a pretty barren but grassy site, some unknown shrubs to the side. It is possible that the soil was brought in when the playground was built. I do not know.

Someone advised me to look and see if the spores in the ascos have different sizes. And from my pictures I can say that this is good observation. 4 larger and 4 smaller spores. I see 2 nuclei.
Spores are ellipsoid to fusiform.
I observed something simliar to secondary spores. Per chance I saw that Schroeteria have similar structures. Sorry, but this is beyond me.


I put together a "data sheet" including spore measurements. I will include further pictures and do still have 2 specimens that I should be able to do more microscopy on if someone will tell me what is necessaary.


I appreciate any help and many thanks.

I also cannot tell. S. trifoliorum would be a possibility, then the large spores whould have 4 nuclei.

The apo with very long stalk could be a different species? Or did you see the same microscopy?

Schroeteria has much bigger oil drops in the spores.

Follow up Another Helotiales - from Salzburg Austria
I set up a better microscope and tried again. The spores are quite variable, they "sprout", they have multi drops, so not just 4 nuclei.
I don't think we can identify this one. I would like to put it in the data bank as "spec".
What would be the proper genus? Sclerotinia or Ciboria?

Re : Another Helotiales - from Salzburg Austria
And I only collected one Asco that day. So the likelyhood of it being "polluted" should be minimal.

Re : Another Helotiales - from Salzburg Austria
Would be the best. In that overmature stage it is difficult to make an ID.
