I have posted a topic about this species as D. chodocola but it turned out to be wrong mainly because of the bracket in spore size.Added files show the difference I only did measure a bracket from 65-72x25-27 um the first time but it proved to be lower than the bracket for D. chodocola. There are some details that are not documented and the bracket for the perithecia is far below the one mentioned in documentations.
Perithecia: embedded with only the top of the neck visible; 511-655420-567 um.
Neck: straight; smooth; no hairs observed; 289-334x179-194 um.
Paraphyses: filiform; abundant; septated; branched; 2.0-2.7 um wide.
Asci: Bitunicate; no apical ring present because the outer wall retracts in total (photo 12) however there is an apical system in the living part (photo 4); 312-326x63-67 um; stolk abruptly separates from ascus in most cases (photo 11); asci swell and extend when in contact with water.
Spores: Biseriate soon becoming uniseriate; immature spores have rounded tops (with exceptions), mature spores conical; transvers occasionally oblique septum with small constriction; surrounded by a gelatinous sheath 3.5-3.5 um swelling in water; 51-72x23-27 um.
