Identification of spore trap spores
Martin Mullett, 29-09-2011 18:05

 Hello all,


I am running a spore trap (Burkhard) in a forest in the southeast of England and am having difficulty identifying some (or many!) of the spores.
I was wondering if anyone recognizes the ones in the photos?  They are very distinct, long (some 100um) and seem to be trapped on a rainy day in middle of June after a long dry period.  Unfortunately nothing is known about the fruiting body.
Does anyone have any ideas??


Many thanks,


Martin

Hi Martin

this reminds me of ascospores of Ophiobolus, üartly broken in two parts, with one cell inflated in the middle.

Hi Martin,

This is almost certainly Ophiobolus acuminatus. I the middle of the constricted (Fig. 2 middle), and it thickened spores are typical for this species.

Re : Identification of spore trap spores
Hello Peter and Zotto,
Yes it is Ophiobolus, it fits perfectly!! Thank you very much for your help!
Can I ask if you think this new photo is a Fusarium species?  It reminds me of Fusarium with a sort of 'heel cell' but it doesn't seem quite right.
Thanks again for your help!

Martin

Re : Identification of spore trap spores
Hi Martin

sorry I can't. But a question: do you always kill the spores that you trap? I think they will not run away if you use tap water instead.

But without joking: I recognize species much easier when the spores are alive, when I see the guttules inside etc. And they are well visible on photos without staining.

Re : Identification of spore trap spores
Haha,
Yes you are right, they shouldn't run away!  But sometimes they do germinate before I am able to have a look at them.  But maybe I will be kinder and not kill them straight away in the future :)

Thanks,

Martin
