Found on cow dung.
Perithecium embedded in the dung whereby only the neck is sticking out. Neck is covered with straight hairs short at the top 130-159 um and longer at the base 500-600 um, both with a width of 4.5-5.5 um, thickwalled 0.9-1.2 um, 5-6 septa hairs constricted but not at the septa.
Asci: Only one mature ascus found containing 512 spores 470x160 um with a short stalk. It is difficult to find an ascus still containing spores because most of the time they collaps and counting the spores will be impossible.
Spores: 18.5-21.5x11.5-13 um, pedicel 13-15x4.5-5.5 um, upper cauda and lower cauda present.


The number of spores are counted by pressing the ascus and spreading the spores, the software is adding a dot and a number to each spore this way counting a great amount of spores is possible (foto-12) and then it's just a matter of counting the end numbers of each overvieuw
The cauda seems to consist of two lashes see foto-8 whereby the end of two lashes is visible by the cauda connected to the pedicel.
When pressing the deck glass caudas becomes extremely long foto-11
Also by pressing the ascus it looks as if the spores are connected to each other by a string when forced out of the ascus. (foto-10)
