Is this a Phaeohelotium on a female catkin of Alnus?
François Bartholomeeusen, 19-06-2024 18:32
On female Alnus catkins I found very small fruit bodies (height < 3 mm; disk < 2mm). The disc had a pink / viollet shade.
Asci: 73x7.5 µm; croziers +; LUG +;
Paraphysis: With refractive guttules,
Spore: (15.6) 16.2 - 18.2 (18.4) × (3.7) 3.9 - 4.67 (4.7) µm; Me = 17.4 × 4.3 µm; Qe = 4.1
Could this be Phaeohelotium epiphyllum?

Thanks in advance,


François

You should try to find living mature asci, also unemptied dead immature asci in IKI for the apical ring shape.

I think the long stipe excludes P. epiphyllum. Is the medulla non-gelatinous and withut crystals?

Living paraphyses with their contents are required.

Dear Zotto,

The medulla is non-gelatinous and without crystals. Right now the FRBs are immature and I cannot determine the apical ring in IKI.

Thank you very much for your quick response!

François

I'm sorry, but I want to show you more pictures. Maybe there are crystals after all? I thought it was a contamination with conidia. I also found a reference to Ombrophila rivulorum which shows a great similarity in appearance.
Maybe an Ombrophila after all?

II think you are now on the right track. Though very small these are crystals in the hymenium.

The living paraphysis cels are here empty. In the last pic it looks a bit like VBs but elongated as typical of Ombrophila.

The genus is very difficult.
