Pyreno with setae on Euphorbia
Maren Kamke, 10-02-2014 18:09
Maren KamkeHi again,
this pyreno is a find on a stem of Euphorbia from the coastal dunes. The perethecia are very small 0,01 mm, setae up to 165 x 5 µm, with septa. I didn't manage to find asci only ascospores which are hyalin, allantoid to fusiform, aseptate, (21-26) 23,45 x 3,9 (3,5-4) µm.
Does somebody have an idea in spite of the missing data?
Regards Maren

Re : Pyreno with setae on Euphorbia
Hi Maren,

I think your specimen is too old or just an old conidiomata. Probably the spores do not belong to the hairy fruitbody at all...

Hi Björn,
I think you might be right that the spores do not belong. There are of course often many different species on one stem.
Thanks
Maren

Re : Pyreno with setae on Euphorbia
Hi Maren,
It looks like a Colletotrichum to me. Telling it's a Colletrotrichum is quite easy, but after... Look at this ref first:
http://studiesinmycology.org/content/73/1.toc
If you find nothing, then the specimen will probably need further studies, and it'd be better to send it to Ulrike Damm at CBS in The Netherlands.

Cheers - LUC.

Re : Pyreno with setae on Euphorbia
I took a bit of time to check. Look at the papers from Fungal Diversity: there's Colletotrichum lineola which has been found on Euphorbia esula in Germany and Canada. The size of conidia's you measured is close to what's given for that taxon.

Now, I don't say it's that species: it's only a hypothesis. Colletotrichum are so difficult and with so many taxa it's an issue for professionals!
Cheers - LUC.
