Diagnostic features
Thallus hyaline. Basal cell of appendage supporting a series of three cells, each bearing solitary antheridia on the inner side, except for the uppermost cell which gives rise two antheridia, where the distal one bears a dorsal spinous process. Perithecium with an oval venter, and a well-distinguished, short neck, which tapers distally into an asymmetrical tip, showing two distinct projections (Fig. 61A, arrows). Perithecial outer wall cells arranged spirally and forming conspicuous ridges and corrugations.[Detailed descriptions: Thaxter 1908; Majewski 1994b; Weir & Rossi 1995, 1997]
Distribution and hosts
Found on five continents: Europe (Spain, France, United Kingdom, Italy, Poland and Finland), America (USA), Asia (India), Africa (Algeria) and Oceania (New Zealand) (Majewski 2008). Recently reported also from Canada, Portugal (Rossi et al. 2013) and Turkey (Rossi 2016). It is common on flies of the genus Scatella (Diptera Ephydridae).
Collections examined from Denmark
On Scatella stagnalis (Fallen, 1813) (Diptera; Ephydridae) DENMARK – Østjylland (EJ) • Gjerlev; 56°35.242′ N, 10°7.898′ E; NH67; Jul. 1882; H.J. Hansen Dry0012; V. Michelsen det.; ZMUC C-F-124025, C-F-124026.
Remarks
First record from Denmark. Although the Danish material is in rather poor condition, it is perfectly identifiable by the two projections from the perithecial apex and the spiral ridges on the venter of the perithecium.
