Pilobolus
Thierry Blondelle, 07-03-2024 23:28
Thierry BlondelleHi,


On poultry droppings mixed with plant debris
I am interested in Zygomycèta which seems to be a Pilobolus in development. The round spores would give the possibility of P. lentiger or P oedipus.
Am I right and what are the differences between the 2 species?

Regards


Thierry

Bonjour Michel,
La clé dont je dispose (de Acta Botanica Brasilica) ne mentionne pas P.lentiger.
Peux-tu m'envoyer la tienne stp ?
Merci d'avance.

Re : Pilobolus
Bonjour.

Par rapport à la forme du sporange et l'épaisseur de la paroi des spores je dirais P.Oedipus, mais ce serait bien si tu pouvais faire une photo des spores à un grossissement plus important pour s'assurer de l'épaisseur des parois.

Michel.

Re : Pilobolus

Je n'observe qu'une seule paroi ce qui nous ramènerait vers Pilobolus lentiger. Confirmes-tu ?

Re : Pilobolus
Bonjour Thierry.

Effectivement j'ai eu un doute ce matin sur oedipus en découvrant ta photo, et lentiger semble la meilleure piste.

Michel.

Re : Pilobolus
I am with Michel and would call this lentiger. I have found oedipus on quite a few occasions and the big difference between that and lentiger (other than the thick wall) is the variation in size of the spores. P lentiger tends to have spores with a range of sizes whereas with oedipus they are a more uniform size.

Re : Pilobolus
Thank you Michel and Mal for the additional information provided.
The difference in spore size in lentiger is indeed clearly visible in my photo.
I still note that this harvest is quite unique on litter made from poultry droppings.

Re : Pilobolus
The only time I found P lentiger it was on unknown but probably bird dung.

Re : Pilobolus
Hello everyone,
Who could provide me with a key to the Pilobolus in which P.lentiger appears?
Thanks in advance.
