Dupla Graecensia Fungorum, C. Scheuer [1-450]
For more detailed information see Fritschiana 54 (2006) p. 10-24. Only 4 complete and 8 incomplete sets are distributed and hence not regarded as exsiccata in the strong sense. Scheuer also issued "Dupla Fungorum" (1997-2001) an unnumbered irregular series with printed labels.
