Ascobolus

Malcolm  GreavesI collected and cultivated a fresh batch of Goose dung and found Ascobolus branthophilus in great number but also found a small number of a second globluar Ascobolus.
This second one had spores that were 31 x 16-17. Some were evenly granular so would fit with A stictoidius but I could find no sign of the musilaginous attachment to the spores. Other spores showed signs of some small uneaven fissures but a second feature was that many of the spores looked to have a loosening perispore. This is something I have not come across in Ascobolus before so is this normal or an important feature.
The asci were also rather squat compared with the stictoideus I have found before.
Suggestions greatfully received.

Re : Ascobolus
Hi Malcom,
I searched into the keys I have and I didn't find both of these 2 species.
Could-you please send me the key you used for these species ?Thanks in advance.

Re : Ascobolus
Hi Michel
A stictoideus (spelt wrong the first mention in my post) is in The world monogaph by Van Brummelen in Persoonia. A branthophilus Dissing sp. nov was described in Opera Botanica 100 1989.
