Eurotiales on moss - teleomorph, and anamorph?
Lothar Krieglsteiner, 20-03-2024 12:34
Lothar Krieglsteineron 26.10.2023 I found a yellow mould growing on the moss Hypnum cupressiforme in the Bavarian Forest (Germany). I only noticed it because I looked for Luteodiscus and something like this, and because of its nice yellow cushions I decided to take it with me. Only at home, under the bino, I noticed that there were small blackish brown spheres, and so my first preparation was this.

The roundish asci and the peculiar form of the spores (like a burger) guided me to the order Eurotiales.
So - I hoped the yellow mould would be a Penicillium or Aspergillus, but it does not at all look this way. The curled hyphae (sporophores) are finely warted, the spores very small.


David Malloch who I contacted in December was so kind to provide me with diverse literature on this topic. But I fear I have no good result - at least not for the premise that teleomorph and yellow anamorph belong together.
Possibly they don't.


Who has thoughts that can bring me further?
Yours, Lothar

(1 collection - 2 detail teleomorph - 3-14 micros teleomorph in KOH j- 15,16 detail of anamorph (and teleomorph) - 17-18 micros anamorph in KOH - 19-29 micros anamorph in Kongo-NH3 - 30-35 micros anamorph in KOH plus Phloxin

Re : Eurotiales on moss - teleomorph, and anamorph?
Hi Lothar,

Fascinating!

I am not sure what this is. I think you may have two species there. As you suggested, the ascospores  resemble those of many Aspergillus species, although the ascomata seem rather dark for most members of that family. The lack of an Aspergillus anamorph is also puzzling.

The yellow species, if it is different, reminds me of an Arthroderma or maybe a Pseudogymnoascus. It is difficult to tell from the photograph if those small spores are ascospores or conidia, but I suspect they are conidia, something like Geomyces.

Probably the best way to resolve this is to isolate the two species in culture.

Re : Eurotiales on moss - teleomorph, and anamorph?
Hello David,
thank you very much for your very quick and detailed response! 
I am not able nor have the opportunity to make cultures. So - if you want I can send you the specimen. It is not copious, and I don`t know if it is still alive for culturing. Likely, I heated it for drying (? - I do not remember).
I am quite sure that the spores of the yellow "mould" are conidia, at least no ascospores.
Perhaps again write to me here how we could go on: lkrieglsteiner@t-online.de
Best regards, Lothar
