--> Rebentischia unicaudata (immature) on Cytisus
William de Jong, 24-02-2021 11:51
Hi,

A few days ago I found Helminthosporium velutinum/genistae (https://waarneming.nl/observation/207729435/) on a dead attached branch of Cytisus scoparius in The Netherlands. Together with this Helminthosporium I found several 8-spored asci: 63,8-76,2 x 14,7-17,3 µm. The spores are narrowed towards one side, with a sept in the middle: 32,2-35,8 x 5,3-5,6 µm. I added some pictures, one in Lugol.
Does anyone have suggestion which species this could be?

Thanks in advance. Regards, William

Hi William,

how about an unmature Rebentischia unicaudata?

Barr 1980:147 "Ascospores hyaline at first"....
