( Thaxter 1931: 304 ) [MB#280610]. – Type : “ On the elytra and abdomen of Trichopteryx Haldemani Lec. , Intervale , N.H. , August, 1901 ”; FH . [ USA ] Fig. 24. Ecteinomyces trichopterophilus Thaxt. A –E . Mature thalli. In C, a very slender and flexuous thallus with up to 43 receptacular cells, and in D a gigantic thallus, both from Acrotrichis intermedia . F . Immature thallus. Antheridia (an) are labelled in A and F. Scale bars: 50 µm. Photographs from slides ZMUC C-F-122497 (A–B, E–F), ZMUC C-F-122653 (C–D). 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.

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.
