Hi!Could this be a Nigrograna? I first thought it

Mirek GrycHello everyone.I'm not sure if it was a branch of
Arnium sudermanniae?

Found on horse dung.Perithecia: 784x587 um with a cilindrical 163x155 um long neck.
Asci: 8-spored; not able to measure the length and width.
Spores: Biseriate; 46.5-52.4x22.4-25.9 um;
Upper cauda; gelatinous, transparent, 62.8-107x9.85-10.75x4.7-5.2 um with a longitudinal furrow almost running the whole length of the cauda, reniform.
Lower cauda; gelatinous, transparent 57.5-111.5x10.2-11 um, hollow.
It looks like both caudae are connected to the spore head by means of a transparent light brown ring. (photo 8)
Because of the length of the spore it has an almost flat side when in side vieuw this in contrast with the spores from A. caballinum.

Re : Arnium sudermanniae?
The dimensions of the spores could correspond, on the other hand the upper cauda should be eccentric. It would also be necessary to verify the presence of a single germ pore and an appical apparatus on the asci.
The perithecia also have numerous hyphoid hairs.

Re : Arnium sudermanniae?
Hello Michel,
I probably did find A, caballinum as well with spore sizes of 34.5-40.4x18.9-20.9 um I will show them in the next topic.
I will look if I can find better species to show you.

Re : Arnium sudermanniae?
Hello Michel,
I am not sure if the following photos of spore heads coincide with A. caballinum mainly because of the furrow occuring in the upper cauda.
The peridium of the perithecia can possibly make a difference although photo-3 looks more like the one from A. sudermanniae but spores sizes do not reach the values as published for this species and remain in the lower range as for Ad. caballinum.
By the way the layers covering the neck (in case of photo-3) consist of long thick walled cells up to the ostiole and the lower neck area is covered with hyphen.

Re : Arnium sudermanniae?
The last photos and measurements that you send in fact make think of caballinum; but also compares with inaequilaterale which spores with two germ pores while those of caballinum have only one pore. The latter also has asci widen at the summits.
Michel.
