In the “1KFG: Deep Sequencing of Ecologically-relevant Dikarya“ project (CSP1974), we aim to sequence additional sampling of genomic diversity within keystone lineages of plant-interacting fungi and saprophytic fungi that are of special ecological importance for understanding terrestrial ecosystems. In addition, comparative genome analysis with saprotrophic, mycorrhizal and pathogenic fungi will provide new insights into the specific and conserved adaptations associated with each fungal lifestyle.

Flagelloscypha is genus of cyphelloid fungi in the Niaceae (Agaricales, Basidiomycota). This group is characterized by the formation of white cup-shaped basidiocarps. Flagelloscypha sp. PMI_526 was isolated from Populus roots as an endophyte and the colonies on Modified Melin-Norkrans (MMN) are whitish to cream color. Clamp connections are present with dikaryotic nuclei typically colocalized within the clamps. Agerer and others have described this group of fungi mostly from litter and twigs. However, recent studies using amplicon sequencing or clone libraries have found Flagelloscypha associated with roots of different hosts including Pinus, Fagus, and Picea. Other species in this genus have been found to produce antibiotics that inhibit bacteria and fungi. This is the case for F. pilatii, which produces the antibiotic pilatin.
