From species delimitation to hypothesis testing: A revision of the European black and white russulas
Dr. Ruben De Lange, Naturkundemuseum Stuttgart
Russula is one of the most colorful and diverse genera of ectomycorrhizal fungi, but not all of its members fit the vibrant stereotype. This presentation delves into the taxonomic mysteries of the duller, lesser-studied subgenera Compactae and Brevipedum, which conceal far more diversity than previously assumed. Through molecular phylogenetics, detailed morphological analysis, and ecological data, we uncover unexpected species richness, describe several new taxa, and propose updated standards for modern fungal descriptions. This research significantly reshapes our understanding of Russula taxonomy.
The talk also explores broader challenges in fungal systematics, emphasizing the importance of integrating historical taxonomy with modern molecular tools, the critical role of type sequencing, and the promise of citizen science in advancing biodiversity research. This directly links my previous work to the goals of the current FunDive project, which aims to improve fungal taxonomy by sequencing fungarium type specimens and anchoring species names to DNA barcodes. In addition, we empower citizen scientists to contribute meaningfully to fungal monitoring and conservation. Together, these efforts are making fungal biodiversity more accessible, accurate, and inclusive.
As usual, we will also broadcast via zoom for those who can not join in person: https://zoom.us/j/94510498226
