Physarum citrinum Schumach. is one of the few of Schumacher's species which has remained unchallenged since it's creation.
Both text and figure indicates a stipitate Physarum species with yellow lime on peridium as well as in stalk. Neither give any information on details such as capillitial structure and limebodies, which today are both considered diagnostic.

Nothing in the short diagnosis and in the figure speakes aginst the general interpretation that Schumacher's species is in accordance with the current view of Physarum citrinum Schumach.

It should be noted that the figure in "Flora Danica" of Physarum citrinum Schumach. is not copied from Schumacher's aquarelle, as is the case of a number of the other myxomycetes in "Flora Danica".

Physarum citrinum Schumach. is accepted as a 'good' species.
