MellAsco 2 - Daldinia concentrica

The MellAsco excursions were rich in Daldinea concentrica (sensu stricto). In the Marais Portevin area the pollarded Fraxinus were a perferred habitat.

Left overnight, these large pyrenomycetes will produce large amounts of black ascospores that deposits in the near surroundings. The spore production peak around midnight.

The stromata are filled with a complicated hyphal structure showing as concentric zones. This helps preserve the water within so the perithecia may continue spore production for days (or weeks) after they are removed from their substrate.
