Including more than 260 taxa, it is the largest collection of Erysiphalean fungi in Europe and covers more than 40 % of the world's known powdery mildew taxa. The oldest specimen (see label on the right) was collected in August 1830, but the collection also contains numerous recently collected specimens.

The Database

Collection sites of the Erysiphales collection "The Erysiphales Collection at M" and – if not stated otherwise – its supporting files, have been copyrighted © 2000–2016 by the Botanische Staatssammlung München, Department of Mycology. Support is provided by the Bundesministerium für Bildung und Forschung (BMBF) and the Bayerisches Staatsministerium für Wissenschaft, Forschung und Kunst. Permission is given for free use of data in the search result for non-commercial purposes; any commercial use must be granted by prior written agreement.

The data project "The Erysiphales Collection at M" was established within the framework of the GLOPP project by D. Triebel and C. Kainz with technical assistance from I. Sebek and A. Pillukat. It uses Diversity Workbench components developed within the framework of the GLOPP project and the GBIF-D mycology project. The ColdFusion webinterface was programmed by W. Spiesberger, M. Weiß and J. Ingenhaag, Botanische Staatssammlung München. The Generic Point Mapper and Google Maps are used as web services to create dynamic maps. Currently "The Erysiphales Collection at M" is maintained and continuously expanded by staff members of the Botanische Staatssammlung München as part of the Mycology.Net project.

The original specimen labels were scanned using LabelScan v. 2.0, a software that provides an automatic recording of barcode labels and the simplified administration of image files (Hagedorn et al. 2000). The file information was imported in the DiversityCollection database to have an easy and direct way of data transcription from digital label images. Illegible label texts were assigned to experts (e.g. for old hand writing or certain exsiccata series). The orthography of fungal names was taken according to the Erysiphales monograph (Braun 1987). All host plant names were checked by IPNI (International Plant Names Index) before including them in the database. Nevertheless, typing and other errors may occur. In such cases we kindly ask the user to contact the editorial staff at the Botanische Staatssammlung München.
