Specimens in the National Herbarium of Victoria, Australia (<scp>MEL</scp>) and in Naturalis Biodiversity Center of Leiden, Netherlands (L) associated with Albertini and Schweinitz's <i>Conspectus fungorum in Lusatiae superioris</i>

Abstract The fate of the fungus specimens used by Johann Baptist von Albertini and Lewis David von Schweinitz for their publication Conspectus fungorum in Lusatiae superioris has been unknown. Some 73 specimens corresponding to new taxa described in this classic mycological text were recently brought to light in the National Herbarium of Victoria (MEL) in Melbourne, Australia. Here, we document the history and provenance of these specimens and analyze them in light of archived manuscripts and correspondence. Our research confirms that the specimens at MEL can be considered original material of the names of new species described in the Conspectus . We also document several specimens that are likely original material in the Persoon fungus collection at Naturalis Biodiversity Center in Leiden, Netherlands (L). Finally, we consider the potential impact of finding original material on Albertini &amp; Schweinitz names that have been neotypified.
