Ascobolus from soil

Lothar Krieglsteiner, 06-06-2017 16:50

Unfortunately, I do not have a picture of the apothecium. It was only one found, during a seminar, on the soil in a deciduous forest (Carpinus, Castanea, Quercus, Prunus avium u.a.) near Sulzbach am Taunus (Germany, Hessen).

At first glance I thought of a small Peziza (apothecium about 1 cm large), but the spores are clearly an Ascobolus.

Can somebody say more than the species only with my micro-fotos?

Best regards, Lothar

Re : Ascobolus from soil

Hello Lothar,

I think it should be A. viridis.
Best regards, Zuzana

Re : Ascobolus from soil

Hi Zuzana,

this was my first thought also - thank you very much!

In the internet I found pictures labelled viridis with a different ornament - but likely they are wrong.

Best regards!

Lothar

Re : Ascobolus from soil

The ornament in Ascobolus can be somewhat variable, but I think the combination of growth on soil and fusoid spores of this size are typical for A. viridis.
Hopefully someone will correct me if I am wrong.

Re : Ascobolus from soil

Hi all,
yes, the ornamentation can be already very variable, here a few older spores photos and three apothecies.
Greetings Peter.

Hallo Lothar,
am Fundort warst du schon 'mal mit Micha und meiner Wenigkeit.
