Reticularia Bull. was validly published in 1787 or 1788 already, by me
ans of a descriptio generico-specifica, not in (1790 or) 1791 as has b
een generally assumed. It is therefore an earlier homonym of Reticular
ia Baumg. (lichens), a name validly published in 1790 but not on the p
age from which it is usually cited. Reticularia alba Bull., the single
included element and original type of Reticularia Bull., is a later t
axonomic synonym of Mucilago crustacea, hence Reticularia Bull. is a l
ater synonym of Mucilago.
