Discomycet on leaves of Acer pseudoplatanus
Gernot Friebes, 06-10-2009 22:05
Hi,

I found the following discomycet on old, wet leaves of Acer pseudoplatanus (5.9.2009). I do not know why but I do not even come to a proper genus (the best genus I came across was Microscypha).
The apothecia were quite tough with a brown, somewhat appressed-hairy margin. The spores were 19-21 x 5 µm, the asci were 8-spored, IKI bb and without croziers. The paraphyses were up to 3 µm wide without any notably content. The hyphae at the margin were brownish incrustet.

Best wishes and many thanks
Gernot

Hi Gernot

the spores wre surely distinctly scutuloid and the leaves sceletonized. This is Hymenoscyphus vacini, also known as Lanzia vacini. Typical are the brownish striae on the exterior. Only on Acer.

here a specimen from around Munich.

Hi Zotto,

oh dear, I should have known that species. Anyway, thank you very much for the help and the nice pictures!
By the way, do you know what vacini means?

Best wishes,

Gernot

It was the collector, V. Vacek.

Do you mean September or was it collected yesterday ? :-)
