Spiked Asco
Malcolm Greaves, 01-04-2021 10:58
Malcolm GreavesCan someone help with the id on this spiked asco. Cultivated on bird dung. A clear/pale flask 0.2 mm with a distinct neck.
It burst when I tried to remove it so I am not sure whether the dark spores (15um) are anything to do with it or just "contamination". The globular elements on the side and at the apex of the neck I assume are part of the specimen(25um).
Thanks
Mal

Re : Spiked Asco
Hi Mal

This looks rather like a species dear to my heart, Melanospora longisetosa - the very first species that I described back in 1982. I'd be happy to have a further look if you can send me material - please dry right away but not too aggressively, the fruit bodies are rather delicate. The asci are deliquescent, so you may have overlooked them.

Best wishes

Paul

Re : Spiked Asco
Thanks for the info Paul. It looks to be a possibility but my only concern is the beak is a bit long and it was/is growing on dung. It would be great if you could examine it. Do I try to remove one or two of the fruitbodies or dry the sample of dung and hope you can find the specimens when rehydrated? 
Mal
Ps a couple more photos of the spores

Re : Spiked Asco
Send me the dung, I'm used to it! We could certainly have a look-alike, but the neck length may vary. Most species of this group seem to be fungal parasites, but this is not always apparent from the material examined.
