L'un d'entre vous aurait-il une idée du Genre auq
Pseudaegerita spec.

Is anyone familiar with the Hyphomycetes genus Pseudaegerita and possibly willing to studie my find?
Found in a strip along a stream on on moist wood of strongly decating trunk of Cytisus scoparius; trunk ± 2 cm diam.
Conidiophores macroscopically barely visible, in large groups scattered or close together, superfical, whitish ore pale ocher, slightly rough, roundish but flattened at the top, sometimes fused together and then longer than high. Not fused bulbils upto 150 µm diam. Conidiophores very easy to remove from the substrate and in particular the smaller bulbils in the colony stuck together during collection with a needle for microscopic examination.
The entire exterior is covered with coral-like outgrowths. Smaller conidiophores have a rather loose structure, showing that the interior consists of smooth, thin-walled, variably shaped (somewhat rounded-angular) cells; cells variabel in length and width, ± 4,7-7 x 4.5-6,5 µm. New cells are formed at two places on the top side of a cell. In this way, chains of cells are formed. The terminal cell is more often branched three times, and these branches are covered with spines of ± 1 µm lenght. Cells of small conidiophores are easy to push apart. In contrasts to this the cells of larger ones are difficult to push apart. Clamps are absent.
Thanks in advance.

Re : Pseudaegerita spec.
It looks like Brocchiosphaera brocchiata to me :)

Re : Pseudaegerita spec.
Hello Francois,
Thank you very much for your response. This is a completely unknown group to me, but step by step I am making progress. How wonderfully shaped is this small species.
I found a Japanese article by Kaoru Yamaguchi et al. from 2020 containing a table with the differences between the various species.
Kind regards,
Marian
