Dear Forum,On decorticated wood of Castanea,I foun
Hello,Found 23-04-2018, on Typha, the Netherlands.
Spore sizes: 24.7-25.2-26.5-26.6-27.2 x 5.1-5.1-5.4-5.4-5.4 µm, Q = 4.9
Is this Phaeosphaeria eustoma?
Greetings, Riet
It certainly fits P. eustoma following the paper on Phaeosphaeria in Canadian Journal of Botany67 (1989) by Shoemaker & Babcock.
P. eustoma only appears in passing in Nova Hedwigia 57 (1993) Khashnobish & Shearer "Reexamination of eight Leptosphaeria species (Ascomycetes: Pleosporales) originally described on Typha" presumably because it was not originally described on that host.
Do you have access to these papers? Let me know if you would like PDFs.
Best wishes
Chris
Thank you for your confirmation!
I alraedy have the PDF on Phaeosphaeria in Canadian Journal of Botany 67 (1989) by Shoemaker & Babcock. This paper helped me a lot.
I would be glad to receive the other PDF.
Best wishes,
Riet
Sincerely,
Hannie
