Hello, I keep finding something with spores like
Hi together,Maybe someone has an idea about this one. It's a setose coelomycete that grew on the lower Surface of dead leaves of Rosa rugosa, directly at the coast of Northern Germany, found by Torsten Richter. In the vicinity, Breviappendix rosae could be found, but on differernt leaves. I'm not sure whether there could be a connection between these two.
Some data:
Conidiomata up to 430 µm accross
Setae: 90 - 180 × 6 - 8.3 µm
Conidia:
(7.5) 8.1 - 9.8 (10.3) × (1.8) 1.82 - 2.2 (2.3) µm
Q = (3.6) 4.3 - 5.1 (5.4) ; N = 20
Me = 9.1 × 2.0 µm ; Qe = 4.6
There do not seem to be any appendages on the conidia. Further, I could not observe conidiogenous cells or the conidiogenesis, what surely does not faciliate determination, but I even don't have any idea so far. If neccessary, I could try to get more details. Any hints are welcome.
Thanks in advance,
Matthias
very interesting.
You can compare with Dinemasporium asetulum.
But this species is report from africa.
best regards,

Compare with Chaetomella oblonga.
This species is described on leaves of Rosa and the micro features fits well.
But conidiogenous cells are present.
vielen Dank, das passt perfekt.
Ich hab nochmal am Exsikkat nachuntersucht, Konidienträger gibt es natürlich, dazu war das erste Präparat nur nicht gut genug. Jetzt hab ich sie gefunden, auch die passen für deinen Vorschlag.
Anbei noch ein paar Bilder.
Viele Grüße
Matthias
