Found on cow dung scattered between P. kleinii species

The fruitbody is hyaline in contrast to the one from P. kleinii which has an orange colour. (Photo 4 & 5)
Spore size 5.5-6.3x3.6-3.9 um

Re : Pilobolus umbonatus??
Hello Joop,
I have no doubts about this species.
Compare also with the wonderful portrait from my friend Matthias at Pilzforum.eu.

Re : Pilobolus umbonatus??
Hello Norbert,
Thanks for you response they are very nice pictures indeed.
I am still busy with stacking of photos here is a result of P. kleinii.
I also did find a subsporangular swelling without a sporangium but the bulb on top of the swelling looks like a sporangium.
After a few minutes is disappeared and closed the swelling as if it was a lid without causing the swelling to collapse, a very peculiar find.
Regards,
Joop

Reallistically the only one you can be sure of without the microscope.
