INVALID, EXCLUDED OR DOUBTFUL NAMES

Based on Spumaria minuta Schumach. G. Lister, Monogr.

(1873)
Cited by Rostafiński, Sluzowce Monogr.: 112 (1874), as a
synonym of Physarum sinuosum (Bull.) Weinm., followed
by later authors. In the reference given Berkeley cited it as a
synonym of the same species, which he called Angioridium
sinuosum (Bull.) Grev. Massee ( 1892) also cited it, but only
to exclude it explicitly from the synonymy of that species. So
far as we can discover, never validly published [M. & A.,
1969: 374].
