Hi everyone,

I found something which seems like Pilobolus on rabbit dung in a dry moorland in the Netherlands last saturday. 

Sp1) Is this P. crystalinus? Spores are quite big: average 12,6 x 8,8 µm (n=15), ranging from 10,8 to 13,9 µm in length, but not yellow/orange at all. 
(See the first 4 pictures)

Sp2) Seems to be the same as 1, but slightly bigger spores (up to 15 µm long), average: 13,4 x 8,6 µm (n=8).
(See 5th and 6th picture)

Sp3) What is this?? very big spores.., right out of a Pilobolus-like sporangia: 29,9-33,3 x 15,3-18,9 µm.
(See last 3 pictures)

Can anyone help identifying above mentioned species?

Thanks in advance.

Kind regards, William de Jong

Re : Pilobolus
Here some pictures of the fruiting bodies as I found them. After taking them home, several got black sporangia which I used for furhter identification. see first message.

Re : Pilobolus
It looks like Pilaira anomala

These don’t look like Pilobolus which should have a swelling below the black sporangia.

Re : Pilaira (moreaui)
Thank you very much for the replies Jacky and Malcolm.   

I thought of Pilaira, but those species seem to be very rare in the Netherlands. Probably because they are overlooked?

I found a paper https://www.researchgate.net/publication/233678649_Taxa_of_Pilaira_Mucorales_Zygomycota_from_China
with a key to Pilaira species. The key rather suggests Pilaira moreaui.
What do you think of this?

And still the third species in my initial post is totally different in size of spores. Any suggestions?

William

Re : Pilobolus
William,

both come on dung from rabit. In Belgium it is not rare but overlooked as you say.
