Secret Code Scent – How Mushrooms Talk to Insects

Fungal spores are usually spread by wind or water. In a few exceptional cases, however, insects play a crucial role – attracted by special, previously little-researched odors. The lecture provides an overview of the current state of research on fungal odor signals and their function in attracting insects for spore dispersal. In the main part, Florian Etl will report on his own research on fragrant tropical mushrooms from Borneo and Costa Rica. Among the species presented will be tree fungi, which attract earwigs; bridal veil fungi, which are visited by beetles, butterflies, and stingless bees; and crust fungi, which attract cockroaches and gall midges. The sometimes characteristic odor profiles of these fungi were chemically analyzed to decipher the composition of the odors and identify key stimuli.

Using photos, videos, and initial research findings, complex, previously little-researched interactions between fungi and insects are shed light on. The results show that some fungi are surprisingly well-adapted to insects in terms of scent and structure – comparable to flowering plants that attract pollinators.

A mushroom trip through Catalonia in Spain

Catalonia is located in northeastern Spain. It is one of the most beautiful regions of the Iberian Peninsula, and its diverse landscape characterizes the entire region. In addition to mycological paradises such as the Pyrenees and Montseny, it is also home to the pearl of all pearls: the Costa Brava. Explore its forests and mushrooms with the help of Catalan biologist and mushroom consultant Juan Martinez, and learn more about two of the most iconic trees and parts of Catalonia's cultural heritage: the cork oak and the pine tree.
