MB#569544 Fig. 71 Proceedings of the American Academy of Arts and Sciences 48: 157 ( Thaxter 1912a , as D. Corynitis ) . – Type : “ On the elytra of CorYnites ruficollis Fabr. , La Plata , No . 1459 ”; FH . [ Argentina ] Diagnostic features Male thalli consisting of 5–8 superposed cells separated by horizontal septa, bearing lateral flask-shaped compound antheridia, and an apical unbranched, unicellular, rounded primary appendage ( Fig. 71D , pa). Female thalli consisting of 4–6 superposed cells separated by horizontal septa. The 2nd and/or 3rd cells bear a unicellular secondary appendage ( Fig. 71A , arrow). The 3rd and/or 4th cells give rise to perithecia. The uppermost cell supports a long, multicellular, unbranched secondary appendage and the rounded primary appendage ( Fig. 71A , *).

Distribution and hosts This species has been reported from Argentina ( type ), USA ( Thaxter 1924 ), United Kingdom ( Hincks 1960 ), France ( Balazuc 1974f ), Italy ( Rossi 1975 ), Spain ( Santamaria 1994 ), Poland ( Majewski 2006 ), Sweden ( Huggert 2010 ), and Czech Republic ( Rossi et al. 2019b ).

Remarks First record from Denmark . This species shows a patchy distribution likely due to lack of investigation, probably because the capture of its hosts is complicated by its specialized habitat, viz., in rotting corpses and other unpleasant-smelling substances such as rotting grains where they feed on the meat-infesting larvae of blow flies ( Calliphora Robineau-Desvoidy, 1830 , Diptera Calliphoridae ), Dermestidae (Coleoptera) and Piophilidae (Diptera) . The cells above the basal cell may undergo divisions giving rise to additional secondary appendages or perithecia.
