Comptes Rendus Hebdomadaires des Séances de l’Académie des Sciences 146: 201 ( Chatton & Picard 1908, as T. histophtorus ). – Type: [In ??] “La Laboulbéniacée que nous avons trouvée sur Menopon pallidum Nitzsch et sur Goniocotes abdominalis P., Mallophages recueillis sur les Poules domestiques à Banyuls-sur-Mer”. [ France]

Diagnostic features

Male thalli yellowish, including many antheridia per thallus; antheridial neck three times shorter than the venter. Female thalli yellowish, including many perithecia per thallus. Perithecia straight, clavate to cylindrical, wrinkled, with small indistinct lips. [Detailed descriptions: Thaxter 1912b, 1926; Bechet & Bechet 1960a, 1960b; Majewski 1994b]

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.
