Abstract

A new species of mycelium-forming yeast,Endomycopsis platypodis Baker et van Rij is described. It occurs as an auxiliary ambrosia fungus of the wood-boring ambrosia beetlePlatypus cylindrus Fab. (Col. Platypodidae) and is the first fungus to become established in new tunnels where it forms a sparse irregular lining. Later a palisade-formingSporothrix becomes the dominant fungus in a mixed ambrosial flora.

E. platypodis, which is apparently homothallic, assimilates nitrate and weakly ferments glucose. The asci typically contain 4 hat-shaped ascospores. Assimilation reactions and morphology are described and the affinities of the new species are discussed.
