They grew on plant debris soaked in faeces together with Byssonectria terrestris.
I have no idea:(

Re : Byssonectria terrestris & asco ???
I suspected Pseudombrophila guldeniae but the spores are different.

Spores looked like that today. I will check in a few days how better they will mature.
Unless it's a different genre?
Thank you Peter.

Re : Byssonectria terrestris & asco ???
As I thought it would not be Pseudombrophila guldeniae.

Fungus so interesting that today again I worked on it a little bit.

Spores poorly mature but on some spores the ornamentation is already visible.
It turns out that it will be Pseudombrophila derrata.
What is your opinion on this subject?

Re : Byssonectria terrestris & asco ???
I think Pseudombrophila merdaria is a good idea.
Mirek Gryc, 01-12-2019 14:34
Re : Byssonectria terrestris & asco ???
I don't give up easily :)
The fruitbodies look ripe so I sit down again.
Hard topic because I have no literature for Pseudombrophila.
Can anyone please send me:
Brummelen, J. van. 1995. A world-monograph of the genus Pseudombrophila.
Thank you in advance.

Hi Mirek,

I agree with Enrique. Look Your mails.

Greetings Peter.

Re : Byssonectria terrestris & asco ???
Hi Enrique & Peter

I would gladly agree with you because I have had enough of this mushroom.

Spore ornamentation does not completely match this species.
You can't see it in the pictures :( I have poor photographic equipment.
When viewing under a microscope, I see only oblique ridges clearly. They are parallel to each other and do not merge.

If I am not mistaken it with P. merdaria ornamentation is more irregular???

Re-measured the spores:

(11.7) 11.9 - 12.9 (13.2) × (6.6) 6.8 - 7.8 (8) µm
Q = (1.5) 1.6 - 1.8 (1.9); N = 22
Me = 12.4 × 7.2 µm; Qe = 1.7

Peter, did I understand you sent me an email?
I haven't received any message?


best regards

Hi Mirek,

I have sent the worldmonograph with TransferNow.

Re : Byssonectria terrestris & asco ???
Hi Peter!
I don't know why but the mail from you doesn't reach me.
I have sent you an email.
If you can, try maybe in the form of an answer.

Spore ornamentation in my collection best suits Pseudombrophila petrakii and P. deerata. I don't know if there are other species with similar ornamentation?

I only have a description of P. deerata.
In my collection, the spores are slightly smaller than in the description of P. deerata.
Hair and other details are appropriate
That is why I wanted to compare with the description in the Brummelen monograph.
Unfortunately, but I don't have this one :(

Re : Byssonectria terrestris & asco ???
I do not have the Brummelen monograph but does it mean that, according to him: P. deerrata = P. merdaria?

I understand well ??

Re : Byssonectria terrestris & asco ???
Yes, P. deerrata is synonymized with P. merdaria. Did you get in the meantime the Brummelen monograph? If not, I can send it to you.

Best, Uwe

Re : Byssonectria terrestris & asco ???
Hi Uwe!
Thanks for explanation.
There is little literature on them on the internet :(

If not a problem then I would be grateful.
I did not get monograph :(
best regards

Re : Byssonectria terrestris & asco ???
Hello all, hello Peter, I'd be interested also in Van Brummelen's Pseudombrophila monography.

Cheers - Luc BAILLY.

Edit: Got it, thanks Peter.

Re : Byssonectria terrestris & asco ???

Thank you all for your help and literature!

I analyzed all species mentioned in the monograph.
I checked all parameters in turn.
I also measured hyphae in individual layers.
The features of my find only match P. petrakii.

Therefore, despite small deviations, I decided to consider my collection as this genre:
1) the "Q" spore parameter; in my case the lower limit (1.7)
2) asci length, just above normal.

I consider the decisive features to be:
1) ornamentation
2) two types of hair
3) dimensions of hyphae in individual layers
4) substrate and habitat

I have analyzed P. merdaria carefully, but too many features do not match. The deviations are so large that I cannot accept them.
