Fries (1829: 88) accepted Schumacher's taxon as a valid species under the name Reticularia plumbea.
The genus Dictydiaethalium was erected by Rostafinski (1873: 5) with Reticularia plumbea (Schumach.) Fr. as the only species and the type of the genus.
The identity of Dictydiaethalium plumbeum (Schumach.) Rostaf. apparently has never been challenged and Schumacher's figure does not give any reason to do so. The aquarelle depicts a quite typical specimen.

Fuligo plumbea Schumach. is accepted as a valid species under the name Dictydiaethalium plumbeum (Schumach.) Rostaf.

Normally Schumacher's figure would be considered as the type of Fuligo plumbea Schumach.
However, at the Natural History Museum of Denmark - Botanical Museum (C) there is a specimen of Dictydiaethalium plumbeum, which is attibuted to Schumacher, se below. This specimen takes precedence of the figure.
