Nectriaceae with white anamorph
Juuso Äikäs, 10-10-2022 13:06
There was a plentiful growth of this red Nectriaceae on the bark of a fallen Salix caprea trunk. It was accompanied by a translucent white anamorph with a paste-like consistency.

Tha wall of the peritechia turned partially purple in 3 % KOH.

Ascospores 2-celled, 10.8 - 17 × 4 - 4.9 µm.

Conidia narrowly cylindrical, 19.8 - 23.5 × 2.7 - 3.1 µm.

Any hope of getting this to species level? Even genus would be nice.

Re : Nectriaceae with white anamorph
Hi,
the Cylindrocarpon anamorph points toward Neonectria. Not an easy group, more characters are needed.
More information in Studies in Mycology 68: 57–78. 2011. doi: 10.3114/sim.2011.68.03

Good luck,

Jacques

Re : Nectriaceae with white anamorph
I have been struggling with Nectria s.l. myself too. From where have you obtained the conidiospores ? I usually fail to get a pure colony to check the anamorph - and it seems you did not grown colonies to get the conidiaspores right ?

Re : Nectriaceae with white anamorph
The conidia are from the white stuff surrounding the red teleomorph. Here's another pic.

Re : Nectriaceae with white anamorph
WOW - never experienced that here in the Mal tese Islands! Hope you deepen your studies to narrow your identification to species level. Thanks for sharing/.
