Table I. — Summarized measurements of conidia of Sclerospora spontanea and 



Sclerospora philippinensis 



Table II. — Biometric constants of the conidia of Sclerospora spontanea and 



Sclerospora philippinensis 



An examination of the data shows clearly that the long-spored Visayan 

 form, Sclerospora spontanea, at least in regard to its conidia, is quite dis- 

 tinct from S. philippinensis. The location of the two frequency curves 

 shows that the great bulk of the conidia of 5. philippinensis fall between 

 the limits of 31 to 36.9 ju in length, and 17 to 18.9 n in width; while, on 

 the contrary, a like proportion of those of 5. spontanea are 37 to 46.9 n 

 in length and 15 to 16.9 n in width. The somewhat irregular character
