OBSERVATIONS ON THE GROWTH OF THE MARINE HYPHOMYCETE VARICOSPORINA RAMULOSA

Abstract
Varicosporina ramulosa, a staurospore-producing fungus, shows a range of morphological characteristics in response to salinity, pH, nutrients, and other changes in the culture medium. Variations in sporulation include encystment of mycelia and conidia, production of chlamydospores, and differences in concentrations of conidium production. Optimal conditions for mycelial growth differ from those stimulating reproduction. These factors possibly affect distribution of the species in the sea and may be significant in the observed paucity of morphologically adapted aquatic Hyphomycetes in estuarine localities.
