Hyphomycet on rotten plant

Thorben Hülsewig, 19-10-2016 20:32

Hi there,
last Sunday i found on rotten plant this hyphomycet with conida who has got a stripe ornamentation. I hope you can help me with the determination.

thanks in advance,
Thorben

Re : Hyphomycet on rotten plant

Lieber Thorben, You should try to find conidiogenous cells. Without seeing these I am quite lost with your pictures. Or at least aa low power view to see how the conidia are arranged on the synnema. Good luck Walter

Re : Hyphomycet on rotten plant

Hallo Walter,
i don't find conidiogenous cells. But i hope this picture can help.

best regards,
Thorben

Re : Hyphomycet on rotten plant

Guten Morgen Thorben. This seems to be a Botryosporium, but I do not recall striate conidia in this genus. Perhaps an artefact of preparration? Cheers Walter

Re : Hyphomycet on rotten plant

Hallo Walter

Possibly that the striate conidia are an artefact.
I'm not sure about this, because i prepare in water with fresh fungus (was 3 hours old).
Sometimes there was conidias with no ornament, but mostly with ornament.
I save the fungus as cf. Botryosporium.

best regards,
Thorben

Re : Hyphomycet on rotten plant

I am working on another Botryosporium found in the wild on acanthus mollis, and I am pretty sure that your species is B. longibrachiatum. The closely related B. pulchellum should have dichot. branched conidiophores.

Best regards
Stephen

Re : Hyphomycet on rotten plant

Hi, Stephen,

I think you might be right with your assumption Botryosporium longibrachiatum.
Unfortunately this cannot be confirmed anymore, because I have no more material.
The probably striped ornamentation of the conidia could perhaps also be a dry damage.

best regards,
Thorben

Re : Hyphomycet on rotten plant

You are welcome Thorben
I agree re shrivelling of spores, although usually they swell up in water. Maybe they require more time for that and you mounter/viewed in a shirt time.

Nice pics by the way.
