Existing correlations of Power law consistency index with biomass concentration and morphology were revised using a microscope magnification of 50 times to characterize the latter, rather than the 80 times used previously. This allowed tests of the correlations on broths of   and  , which have such large mycelial sizes that a lower magnification is required for accurate morphological analysis. The new correlations were successful at predicting the rheology of   broths but not   broths, which may be because of a change in the exponent on the biomass concentration in the correlations for the latter. Because the mean maximum dimension of clumps is magnification independent, the preferred correlation was:where is the consistency index (Pa s), is the biomass concentration as dry cell weight (g l) and is the mean maximum dimension (μm).
