In 2013, Ascomycete.org launched a project for an inventory of Ascomycota found in Alpine zone. Indeed, its mycobiota, especially the smallest fungi like Ascomycota, is still an under-prospected group and the literature on this subject is rather sparse. The biotopes of the Alpine zone (grasslands, small lakes, wetlands, etc.) are though very interesting due to their floristic originality and their adaptation to altitude conditions and climatic hazards. A part of this mycobiota is also found in the retinue of boreo-arctic ascomycetes, but we found interesting to make a fundamental work to improve our knowledge of Alpine Ascomycota. Thus, each year we organize a study session in August to prospect the Alpine zone or upper Subalpine zone looking for these little wonders.
