Abstract
The green alga Elliptochloris bilobata, formerly found lichenized with Catolechia wahlenbergii, also occurs as phycobiont of Protothelenella corrosa, Pr. sphinctrinoides and Baeomyces rufus. When lichenized, it has relatively large spherical or broad ellipsoidal cells without a gelatinous sheath and reproduces by two or four + spherical autospores. Small rod-like daughter cells are found in greater numbers (in Protothelenella besides others) when the alga looses contact with the fungus. This in parts, intermingled with the primitive crustose thallus of Protothelenella, also leads to the formation of gelatinous confluent mucilage. Under the cultural conditions used, a sheath is lacking. The systematic affinities of E. bilobata are discussed.
