Nectriella sp. on Impatiens
Björn Wergen, 24-05-2013 12:23
Björn WergenHi friends,

I have found another Nectriella, which is near N. dakotensis, but with verrucose, bigger spores and longer setae. It has very small 0,1 mm broad, orange yellow fruitbodies with a distinct whitish ostiolus and surrounding, redbrown setae. I have tried to find this out with Rossman's Family of Bionectriaceae, but stucked between N. alpina and N. halonata, which do not fit this finding.

Short description:
Sp. 11-16x2,5-4µm, slightly verrucose, 1septate. Asci 45-55x6-7µm. setae 60-90x5-6µm. On Impatiens glandulifera.

Any other ideas?

regards,
björn

edit: I think this IS N. halonata. Probably a small spored form?

Hi, Björn,
did you test KOH and lactic acid?

Regards,
Christian

Hi Christian. What does KOH do? I will test it directly.

I have tested it, but there was no reaction either with KOH nor with lactic acid.

Re : Nectriella sp. on Impatiens
I think your fungus is not N. halonata, I saw this species, it is not like this. Could you show an image of the ascomatal wall in vertical section?

Re : Nectriella sp. on Impatiens
Hmmm the fruitbodies are very soft and impossible for me to cut. What can I do? Just drying?
