Re : Geoglossum sp. x2
Hi Andy
I think this need images of more and well-developed spores. I do not know what these spores with constrictions are. They look more like conidia.
Important is to look at living asci. is your material still fresh? Take photos of asci with spores inside, and do not apply any pressure. Then you hjave the chance to see many turgescent asci. It is possible that your first specimen concerns G. fallax. if so the spores must be hyaline inside the living asci and turn brown only a reasonalbe time after ejection (or within dead asci). Most other Geoglossums eject brown spores.

Re : Geoglossum sp. x2
Thanks Otto,
The material is fairly fresh, I have been keeping them in the fridge, would this effect the structures adversely in any way? The first specimen shows dark spores in the ascus, 1st image below, the second, for the second species, shows hyaline spores in the ascus. Would you have any idea as to what the spear-headed looking spores in the ascus of the second image may be? Andy

Re : Geoglossum sp. x2
The left images shows a dead ascus. So this says little.
The tow asci right look alive, so they might eject hyaline spores. I never saw such swollen spore apex in Geoglossaceae. Maybe this is caused by the fridge?
here living asci that eject living spores (G. cf. hakelieri, phot. B. Fellmann).
