Hello,

the correct citation should probably be: Imbach, E.J. (1951). Baeospora myriadophylla (Peck) Singer forma cavernalis; Lenzites cinnabarina (Secretan). Bulletin Suisse Mycol. 29: 169-175. 
However, I got no better results while searching for it.

Hello Vicktoie,

Thank you for the alternate name for the journal and for the correct citation. It may help in the search. My information came from Mycobank.

As far as I know, the papers in this journal often have three language mutations (DE, IT, FR) so perhaps the name of the journal corresponds with the version that was read and cited? I don't know whether the german name is the official one.

My source was Herink's 1953 paper in Ceska mykologie, cited as "IMBACH E. J., (Schweiz. Zeitschr. f. Pilzk. 29 : 169—173, 1951) — Baeospora myriadophylla f. cavernatilis FAVRE J., FURRER C. et HALLER R. ap. IMBACH E. J., l. c. p. 172—3" (online: http://www.czechmycology.org/_cm/CM072.pdf#page=35), the paper name I found on cyberliber (searched articles by Imbach). 
The different final pages (173 vs. 175) correspond with different journal name, so they might really refer to another language version.

Thank you Vicktorie, that could be a useful article but I am not able to read Czech. The summary is some help. Perhaps a machine translation can be made. I'll work on that. As you say, the journal appears to have two, or perhaps three, names. Something to work with!
