Trichobolus

The length of the setae points to T. zukalii, but the spore size is not quite right?
Spores 8.7 x 7.4 µ with Bary bubbles.
Only fruit bodies full of spores were found, no asci.
Setae length on average 350µ
Identification Ellis&Ellis.
Is this T. zukalii?
Thanks in advance, Margot

Re : Trichobolus
Hello Margot,
your description fits best with T. zukalii to known other species that I can find. The ascus is almost the whole fruit body itself containing all the spores ranging from 1000 > 4000 sometimes depending on age. The setae fits well. This could also be the reason why your spores are slightly smaller but I suggest within range. The odd thing about these species is that Paul Cannon (Kew) states that this and other close species do not have deBary bubbles or oil spots etc. Perhaps there is a easy explanation for this but I am not aware. see:
https://fungi.myspecies.info/all-fungi/trichobolus-zukalii
I assume the examination was made with water as meltzers seem to expand the size of the spores.
regards

Re : Trichobolus
Thanks Tony for the answer.
The measurements were carried out in water.
I read on this site that some varieties do have deBary bubbles, but I cannot find which species:

Re : Trichobolus
I foumd this article that provides a key to Trichobolus plus others. Hope this helps.

Re : Trichobolus
Hello Margot and Tony,
I know Trichobolus zukalii from nearly 50 finds and T. sphaerosporus from more than 10! In my opinion the best way for separation is the spore quotient. It is in middle 1,19 for zukalii and 1,07 for sphaerosporus (Doveri, FFI, 2004).
Regards, Norbert

Re : Trichobolus
Thank you both.
Tony, the key also takes you to T. zukalii.
Norbert, our spore quotiënt is 1.1 x 1.2 ( foto 4) this also points most to T. zukalii? Have you seen the Bary bubbles during these 50 observations?
Kind regards, Margot

Hello Margot
Same opinion as Norbert; what did you prepare for?

Sorry Michel, I don't understand what you mean by "what did you prepare for"?

Re : Trichobolus
Excuse me, what liquid (only water?) do you use to make your Trichobolus preparations. Some can cause artifacts and modify certain details (this about spores and Bary's bubbles).
Michel.

Re : Trichobolus
Tony also asked the same in the first answer :) everything was viewed and measured in water.

"Have you seen the Bary bubbles during these 50 observations?"
Yes, I did. But only on dried material, which was re-moisturized. The bubbles were thick-walled, just like you show.
Regards, Norbert
PS. Also I notized: Spores 8,5-9 x 6-7,5 µm when unripe!

"Yes, I did. But only on dried material, which was re-moisturized. The bubbles were thick-walled, just like you show".
This could very well be the explanation, because this could also have happened in nature before I found it.
Thanks and kind regards,
