Joop van der LeeFound on cow dung.

Apothecia: white cylindrical at first becoming more flat with a lemmon-yellow center and global cell on the edge showing ripe tips of asci.
Excipilum: white covered with ellipsoid and angular cells.
Mature disks are yellow, flat at first with global cells on the edge becoming concave without the global cells.

Paraphyses: septate, cylindrical, 2.2-5.1 um enlarging to 7.5-11.5 in some cases.

Asci: 8-spored, when enlarging in length with spores in line 222.5-240.5x21.5-27. When exanding in width in order to regroup the spores in two obliquely groups of 4 they measure 182.5-198.5x33-37 um.

Uniseriate at first, finally biseriate, ellipsoid, hyaline at first and dark violet at maturity covered with a thick layer broken by irregular longitudinal furrows 20.5-23.5 (-27.5) um.
With a unilateral substance.

The last page of the enclosed documentation by Boudier gives an impression of the furrows in the spore layer. 
Nice drawings for showing how it looks like in reality in the 19th century
