Saccobolus
M. M. Gotink, 02-06-2010 00:15
On hare dung in a moist container again...

Apothecia very small (<500 µm), yellowish.
Asci 8-spored, 100-140 x 35-40 µm.
Spores in clusters of 4 rows of 2 longitudinally arranged spores (like Saccobolus glaber), clusters 45-48 x 15-17 µm, with a gelatinous sheet. Spores 18-20 x 8-9 µm, very finely warted and with some cracks.

Using Ellis&Ellis + Keys to fungi on dung only Saccobolus versicolor and S. citrinus seems to fit, but the first has the clusters arranged differently, and the latter has more obvious yellow colored aphotecia and more conspicuous warts on the spores.
But I just found a little bit information of Brummelen (1967), which seems to give smaller spore and cluster sizes for most species, this way S. glaber comes in sight again and another species: S. succineus.

Using some danish key which has all the said species I think it actually might be S. succineus. The pale color, cluster size, spore size and spore ornamentation all seem to fit.
But I would like a second opinion since I'm still very unsure due to all the different information and my unfamiliarity with Saccobolus...

Re:Saccobolus
Hello.
The genus Saccobolus is difficult; succineus and citrinus are close, but actually succineus spores have finer and denser warts, and darker color than citrinus which are more purple.
Michel.

Re:Saccobolus
Hi Michel,

The warts on my spores were very fine and dense, not like the warts of S. citrinus I've seen in the different keys. But the mature spores were clearly dark purple as you can see on my photo's...

Re:Saccobolus
Hi Martin,

As Michel has already written is Saccobolus a very difficult race. There is, in my view, more open-ended questions such as questions clarified. In particular, the assessment of the spore cluster is not easy. The color of the spores and the very variable but surely ornament plays only a minor role. For me, this is, on the basis of spore size and color (yellow) Saccobolus citrinus.

Re:Saccobolus
Hi Peter,

Ok, I'll call it a Saccobolus cf. citrinus. Didn't expect Saccobolus to be this difficult in the beginning... Thanks.
