Type: “ On the elytra and abdomen of Trichopteryx Haldemani Lec. , Intervale , N.H., August, 1901 ”; FH. [ USA]

Diagnostic features

Receptacle uniseriate, consisting of a row of 3–28(–43) cells. Most of the appendage cells give rise to 1–2 corner cells that function as simple antheridia in young thalli. Perithecium with a broad, ovoidal venter and an abruptly distinguished, straight and slender neck. [Detailed descriptions: Thaxter 1908; Majewski 1994b; Weir 1994; Santamaria 2003; De Kesel 2010]

On Acrotrichis thoracica (Waltl, 1838) (Col. Ptiliidae )

DENMARK – Østjylland (EJ) • Horsens ; 55°51.580′ N, 9°50.646′ E; NG59; 13 Apr. 1947; Høeg DrY0036; Høeg det.; ZMUC C-F-124102 .

Remarks

As a curiosity, Majewski (2008) mentioned that this species is exceptionally common in Poland and that it is fair to expect it to be common in other countries. In Denmark, E. trichopterophilus is also extremely common and is rare not to find it in a collection with specimens of Acrotrichis . Thalli are very variable in receptacle length and perithecial neck. In Fig. 24D a gigantic thallus is photographed, and in Fig. 24 C we show a very slender and flexuous thallus with up to 43 cells in the receptacle. Majewski (1994b) described up to three morphological types, without any taxonomical rank. We are not capable of distinguishing these groups among the Danish specimens.
