On Rhamnus frangula
Aafke Buijs, 21-07-2015 17:09
Hello,

Found these partly immersed black fruitbodies on wet twig of Rhamnus frangula, some solitair, most of them in small groups on a black underground (under the bark).
Asci with 6-8 spores, about 120, with thick walls and gelatinous content between the spores, as it looks to me.
Spores colourless when young and brownish when mature. Mature spores 20-23/7-9.
Mature spores with 3, but mostly more, transverse and longitudinal septa, different from the description and the picture in Ellis & Ellis.

Could this still be Karstenula rhodostoma ?

Greetings, Aafke

Re : On Rhamnus frangula
This is Cucurbitaria rhamni. I am presently working on Cucurbitaria. If you want you can send me some material.
Best regards, Walter

Re : On Rhamnus frangula
Hi Walter,

Of course, that's it ! Strangely I did look for Frangula instead of Rhamnus in the book of Ellis. Must be the warmth !
Thanks.
Could you give me your address by email in order to provide you with the rest of my finding ?

Regards,
Aafke
