A macroconidial synanamorph of Kendrickiella phycomyces (Pezizomycotina incertae sedis).

A macroconidial synanamorph, namely a phragmosporous phialidic morph of Kendrickiella phycomyces (Pezizomycotina incertae sedis), was newly observed in authentic cultures isolated from the Kitora and Takamatsuzuka Tumuli in Japan. The synanamorph was sparsely produced throughout of the colonies on PDA after a few days at room temperature in cultures revived from lyophiles or in streak cultures, both derived from germinated Kendrickiella-type aseptate microconidia. After 1-2 wk, the microconidial synanamorph (the Kendrickiella-type synanamorph) and creeping hyphae completely overgrew the macroconidial morph produced on the colony surface. This sparsely produced morph appears to be a common cultural character in K. phycomyces with pleomorphic conidiation. The morphology of the macroconidial morph is described and the taxonomy of K. phycomyces is briefly reviewed and discussed.
