Mick PeerdemanHi all,One of my earliest microscopy attempts, so
On Rhamnus frangula
Aafke Buijs,

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 ?
