There seems to have been a general agreement on the interpretation that Trichia venosa Schumach. is a synonym of Hemitrichia serpula (Scop.) Rostaf. ex Lister.
Both the printed text and in particular Schumacher's reference to Lycoperdon lumbricale Batsch support this view.

Schumacher's illustration, however, opens to another more likely interpretation: a myxomycete sclerotium, possibly of Badhamia utricularis (Bull.) Berk.
Læssøe & Kemp (2001) were the first to point to this possibility. In a report on two finds of Hemitrichia serpula (Scop.) Rostaf. ex Lister. they convincingly argue that Schumacher depicted a myxomycete sclerotium, and that their find of H. serpula are the first Danish records. The present author agrees.

Trichia venosa Schumach. cannot reliably be attributed to any known myxomycete species and should be considered a nomen dubium.
