Chaetoplea spec.??

Stefan Blaser, 17-04-2020 13:25

Dear all,

It would be great if anybody could make a suggestion considering this collection.

As it may be a Chaetoplea species, I would also be very thankful for any Literature on this genus.

Ecology: On dead branch of Castanea

Macro:

Perithecia globose, black, about 300 µm in diameter, collapsed when dry

Micro:

Asci: saccate, 42-50 x 22-25 µm

Spores: Dictyosporous, greyish brown, with 3 (-4-6) transversal and 1(-2) longitudinal septa, mostly 14-17 x 8-9 µm, some Spores prolonged up to 23 µm.

Perithecial wall: Angular to rounded, brown cells with a diameter of 5-10 µm

Any help would be very welcome.

Best wishes,

Stefan

Re : Chaetoplea spec.??

Hi Stefan,

Toay, it's difficult to say what is Chaetoplea. Your fungus is probably close to Thyridium.

Please, contact Hermann Voglmayr.
