Distribution and hosts

Occurs on Mallophaga (Phthiraptera) belonging to many genera of Menoponidae and Philopteridae like Menopon Nitzsch, 1818, Goniocotes Burmeister, 1838, Menacanthus Neumann, 1912, etc., recorded on several groups of birds (Tavares 1985). Reported from Europe (France, Poland, Germany, Romania, Czech Republic, Italy, Hungary), America (USA, Bahamas, Argentina, Guatemala, Jamaica), and Japan (Majewski 2008). A total revision of the records list would require a huge effort.

Remarks

First record from Denmark. The presence of this fungus in Denmark is not surprising for such a widespread species. The collections are very old, and the fungi are in imperfect condition probably due to the unsuitable preservation fluid; nevertheless the species is perfectly identifiable.
