A, Maximum percentage obtained, disregarding the time element ; B, percentage of 
germination in 20 hours ; C, rate of growth of the thalli in 20 hours (shown in 
microns). These values are not to be considered as absolute for any of the species, 
nor are they necessarily comparable species with species, but they represent the values 
obtained with the spores available.

at 46° C. (115° F.), with most rapid germination at 34° C. (93° R).
