I have one sample of the Schizothecium with 4-spores asci on domestic rabbit dung, over the identification of which I have been suffering for several months.

Perithecia semi-immersed, dark brown to blackish, broadly ovoid to pyriform; agglutinated scales 25,5-38,7 ?m. Asci 4-spored, cylindric-clavate, 90-125 × 12,5-13 ?m. Ascospores uniseriate, apical dark cell (head) 15,30-18,41× 8,92-10,57 ?m; olivaceous to dark brown, ellipsoidal, with an apical germ pore, somewhat flattened at the base and a slightly umbonate at the apex; pedicel 10 × 2,2 ?m; upper cauda lash-like, the lower one similar, attached to distal end of the pedicel.

This sample will occupy an intermediate between Sch. nanum and Sch. tetrasporum. In the works that I have, there is no fungus with such characteristics.

I hope for your help! Thank you!
