Haustoria of the Mycoparasitic Heterobasidiomycete Christiansenia pallida

Abstract

The ultrastructure of the host parasite interaction in heterobasidiomycetous mycoparasites has been studied only in a few species. In Tetragoniomyces uliginosus (Karst.) Oberw. and Bandoni (Oberwinkler and Bandoni 1981) and Carcinomyces effibulatus (Ginns and Sunhede) Oberw. and Bandoni (Oberwinkler and Bandoni 1982), haustorial cells attach to their host cells, Rhizoctonia sp. and Collybia dryophila (Fr.) Kummer, respectively. Haustoria of Christiansenia pallida Hauerslev penetrate the host cells of Phanerochaete cremea (Bres.) Parm. (Oberwinkler and Bandoni 1982, Oberwinkler et al. 1884). A direct connection from cytoplasm to cytoplasm of host and parasite cell has recently been described from T. uliginosus (Bauer and Oberwinkler 1990). In this report, we have restudied ultrastructural characters of the cellular interaction between C. pallida and P. cremea. The ultrastructural features are described in detail. For morphological details we refer to the publications of Oberwinkler and Bandoni (1982) and Oberwinkler et al, (1984). © 1990, Japan Mendel Society, International Society of Cytology.
