On water agar, 30 out of 81 species of fungi tested showed positive directional hyphal growth towards microcolonies of the green alga Protococcus sp. and produced coralloid masses of branched assimilative hyphae within the invaded algal colonies. Of 77 species of fungi tested against the blue-green alga Synechococcus elongatus, 33 exhibited this same phenomenon. Cell walls of S. elongatus were subsequently lysed while only cell death occurred in Protococcus sp., resulting in the release of the contents that were presumably absorbed by the coralloid hyphae. Branched hyphae from some invading fungi occasionally attached to larger individual cells of Protococcus sp., penetrated the walls, and absorbed the contents. Key words: algae, Chlorophyta, Cyanophyta, cyanobacteria, Basidiomycota, wood decay, nitrogen requirements, Protococcus, Synechococcus.

Agmenellum Quadruplicatum

Agmenellum quadruplicatum is a unicellular, non-nitrogen-fixing, marine cyanobacterium (blue-green alga). The ultrastructure of this organism, when grown in the laboratory with all necessary nutrients, has been characterized thoroughly. In contrast, little is known of its ultrastructure in the specific nutrient-limiting conditions typical of its natural habitat. Iron is one of the nutrients likely to limit this organism in such natural environments. It is also of great importance metabolically, being required for both photosynthesis and assimilation of nitrate. The purpose of this study was to assess the effects (if any) of iron limitation on the ultrastructure of A. quadruplicatum. It was part of a broader endeavor to elucidate the ultrastructure of cyanobacteria in natural systemsActively growing cells were placed in a growth medium containing 1% of its usual iron. The cultures were then sampled periodically for 10 days and prepared for thin sectioning TEM to assess the effects of iron limitation.
