Pseudaegerita spec.

Marian Jagers, 22-04-2026 20:17

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.

Marian

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

Re : Pseudaegerita spec.

Hoi Marian,

it looks like Pseudaegerita and Candelabrum are the same, both are synonimized with Hyaloscypha (Index Fungorum). in K. Yamaguchi et al. / Mycoscience 61 (2020) 265-281 the genus Brocchiosphaera is separated here from Candelabrum and put in Sordariomycetes.

The morphological differences are not very clear to me.

cheers,

Stip

Re : Pseudaegerita spec.

Stip, Thank you too for your information. I checked Index Fungorum. According to Fungorum Pseudaegerita and Candelabrum are the same, both are synonimized with Hyaloscypha. I also checked Brocchiosphaera and this genus has been accepted; classified as Incertae sedis in Pisorisoriales.

I also have read the article by Yamaguchi (2020) and a part of the literature cited in the references (including that of Voglmayr (1998). The key in Voglmayr contains six species of the genus Candelabrum s.l. The key guided me to C. brocchiata. The seventh species (B. bulbiformis.) could be excluded with the tabel in Yamaguchi.

So, based on colour, size and absence of a basal plate (I checked this again for more certainty) my find is indeed C. brocchiata.

Thank you both. I wouldn't have figured this out without your help and Stip, I will email you personally (again) regarding the next steps for this Dutch find.
