Little black asco on dead Hedera helix leaves

Hi,

today, when collecting a dead leave of Hedera helix with lots of black dots on it, I was pretty sure I found Trochila craterium.

But under the miscoscope I found most Asci empty. In one good Ascus I found spores of 18-20 - 5-6 µ. Several others had only round drops of different size.

As the spore measurement does not fit Trochila craterium, what did I find?

Collected near Luebeck, N Germany, 2nd April 2020.

Thanks & regards

Chris

I agree, except that it is not clear whether Laurus (britannica) and Hedera have the same fungus. I have it as E. hederae nom. prov. in my folders.

No sequence of either of them appears to exist, so this would be helpful in clarifiying the distinction as well as the uncertain family placement.
