Quite a puzzle
hannie wijers, 27-04-2013 15:57
Last week I found on  twig of Rubus these black frb with a whitish spot in it. Curous as I am, I wanted to kno what this could be, I put it under de bino and I thought; "oh it looks like a puzzle". I think there are a couple of spores? I only know the size of the moon-formed (conidien)spores? Thes are 20-22 x 4 µm.

Maybe someone  can shine a light on it for me?


Thanks

Re : Quite a puzzle
Dear Hannie,

I can't say anything constructive about these two dark-spored fungi, unfortunately.
The last one, moon-shaped, looks like conidium of Fusarium, the green colour is strange, however - is it some abberration? If it's conidium, then this white cluster on photo 8 would be the sporodochium of Fusarium (it seems to produce these moon-shaped conidia?).
Interesting thing is, that there are several "white-black" associations. Then it is possible, that the fungus with small, two-celled dark spored (and perithecia) is a teleomorph (maybe Gibberella? I don't know if they have dark spores?), and the white is an anamorph (i.e. Fusarium). Yet this is just an idea.
The third one - no idea at all..

Best wishes,
Mateusz

Re : Quite a puzzle
Hello Hannie
images 6,7 and 8 show the teliospores of the rust fungus Phragmidium bulbosum - presumably strays from living or dead leaves
images 4 and 5 seem to show the conidia of a Diplodia; given the substrate D. rubi would be the most likely candidate - what were the dimensions of the conidia?
image 7 (upper right middle) shows a conidium of Seimatosporium lichenicola, the imperfect stage of Discostroma corticola, and a very common fungus found on dead Rubus fruticosus stems

amitiés

Re : Quite a puzzle
Mateusz and Chris, my compliments. I hadt expect that someone should have known what all this could be. But I'm happy with it, i can study to these kind of fungi.
Both thanks a lot.


Best wishes

Re : Quite a puzzle
Chris I don't kow what the dimensions of the conidia are. Mostly I have to write it all down and I forgot it this time, sorry.


Best wishes
