extent that this character cannot be rehed on. The first 

 eight of the species of Hypocrella Usted above are usually 

 subglobose, roughly about two-thirds of a sphere, with a flat 

 base. The next three are flattened convex, or scutate. But 

 H. marginata occurs in both forms, according to the shape of 

 the scale insect on which it is growing, and it appears probable 

 that the same may ultimately be found to be true of the other 

 species also. H. Gartneriana, H. scMzostachyi, and H. javanica 

 are again usually subglobose in general outline, but the 

 surface of the stroma is lobed, strongly in the first two species, 

 and either lobed or nearly smooth in the third. H. amomi is 

 a botryose form, and resembles a cluster of perithecia seated 

 on a stroma. 



H. phyllogena is typically stud-shaped, but occurs in a 

 merely pulvinate form also, as shown in Moller's figures. Its 

 Aschersonia stage is found in the same forms. 



Of the unattached species of Aschersonia, A. coffeae is 

 subglobose, while A. cubensis and A. oxystoma are, in general, 

 columnar-cylindric .
