“…Noteworthy is Mario Orsenigo's clear vision into the future of preserving isolates in a central culture collection (CBS) and d'Oliveira's and Sardiña's accurate phytopathological studies. It is also worth mentioning that Juan Rodriguez Sardiña was sent into intellectual exile from Madrid to Galicia, to an institute of inferior category, because he had continued to lecture under the Republican government during the Spanish Civil War (Fernández Prieto, 2012; Fraga Vázquez, 2023). We owe him an extremely careful pathological study and storage of isolates from plantations of Japanese chestnut in north Spain, preserving an invaluable resource for future scientific study.…”

Fungi of the genus Cryphonectria are of special interest to tree pathologists because they cause bark disease in numerous species of the Fagaceae and Betulaceae. Despite this special attention, several Cryphonectria species were not recognized as such for a long time. This also affected the identity of eight isolates with outdated names that have been deposited in our laboratory since 1954. The present study reconstructs the history of the Cryphonectria cultures M282–M289 using primary bibliographic sources. To verify the species identity, all isolates were DNA barcoded and taxonomic affiliation was assessed using a phylogenetic approach. The taxonomic identity combined with the history of the isolates confirms that the chestnut blight epidemic (Cryphonectria parasitica) in Spain was caused by the planting of Asian chestnuts and that the first documented case of bark canker in 1940 was caused by Cryphonectria radicalis on Japanese chestnuts imported from France. The history of isolate M289 could be traced back to CBS 165.32, which proved to be the oldest preserved isolate of the rare Cryphonectria naterciae, confirming the presence of this fungus in Europe for at least 100 years. Based on the ITS barcoding of the 32‐year‐old type specimen, Cryphonectria decipiens must be reclassified as a later synonym of Cryphonectria radicalis. The reconstruction of the history of isolates M282–M289 takes us on a scientific journey from Italy to France, Spain and Portugal in the early twentieth century and offers new insights into the historical context of the invasion of Cryphonectria parasitica in Europe.
