| "Spumaria physaroides DC. Fr. 2. p. 101. fide accuratae descriptionis" [Cited by Fries, Syst. mycol. 3:124. 1829, as a synonym of Didymium crustaceum Fr. The reference is evidently to de Candolle, in Lamarck & de Candolle, Fl. franç., ed. 3, 5:101. 1815, but de Candolle cites Spumaria physaroides Pers., Syn. meth. fung. 163. 1801, and the description there given would seem to apply better to Mucilago crustacea than to what is now called Didymium crustaceum. This raises a question about the validity of applying Fries's name. (apud Martin & Alexopoulos, Myxomycetes 382. 1969)] |
