Tiny yellow apothecia on soil crust
Jan Eckstein,
29-01-2022 21:44
Good evening,
apothecia small, yellowish, 150-300 µm wide, growing in a soil crust of algae, protonema, and lichen thallus (Placynthiella icmalea), asci J-, spores 3-septate, hyaline, ellipsoid, 15-22 x 5-7 µm, with many droplets, paraphyses very slender, 1-1.5 µm wide
ecology: on ant hill in dry grasland
Does someone has an idea?
With best wishes
Jan

Re : Tiny yellow apothecia on soil crust
Dear Viktorie,
thank you very much for your suggestion! The fungus 'Coryne' terrestris looks similar but I'm not convinced it is my species. The spores are somewhat shorter and don't show the characteristic droplets as in my collection. Unfortunately, I cannot find the folder 'Calycellina' in Zottos Ascomycetes illustrations. In Velenovsky's description of Coryne terrestris size of apothecia is 1-1.5 mm, much larger than in my collection.
With best wishes
Jan

Re : Tiny yellow apothecia on soil crust
Dear Jan,
maybe you found the name in the meantime or not?
my guess is it is an ephemeral lichen from Stictidaceae, I would call this Absconditella trivialis,
I expect you collected the stuff in colder or wetter period of the year (i.e. not in hot summer), I know the species growing usually on wet sandy soil covered by algae and pioneer lichens / bryophytes, from road- and railway- embankments or sandpits,
only my specimens were less yellowish, if I remember well
best regards Zden?k

Re : Tiny yellow apothecia on soil crust - identified as Absconditella trivialis
Dear Zdenek,
Thank you very much for your suggestion Absconditella trivialis! I looked up this species and think your identification is right. I found it in January with apothecia growing within an algae crust. The habitat was an old ant hill in a dry grassland community where I usually find bryophilous ascomycetes in winter like Octospora and Lamprospora.
