Abstract For a comprehensive study of phototropism in sporangiophores of the fungus Phycomyces, quantitative treatment of spatial aspects is necessary. The first step in quantifying spatial factors of phototropic signal processing is the elucidation of the non-uniform light profile, predominantly caused by a lens effect in the cylindrical body of the sporangiophore. Herein we compare recently presented theoretical and experimental studies of light profiles. Errors and ambiguities arising from instrumental limitations and arbitrary assumptions are revealed. On the other hand, by combining theoretical and experimental results we have been able to select out the reliable information, which can now be applied in phototropic studies.
