and consisting mainly of the colourless membranaceous epidermis 
which ultimately ruptures and leaves a bole ; scarce, minute 
black pustules on upper surface. 
Perithecia innate, ultimately slightly erumpent through colour¬ 
less epidermis, dark-brown with greenish tint, rough surface and 
irregularly round, flattened, membranaceous, 170p. diarn. with 
round central pore 1op. diatn. 
Sporules hyaline, straight or very slightly curved, rod-like, 
rounded at both ends, but may slightly taper towards one end, 
distinctly and regularly 3-sept ate, not constricted at septa, very 
constant in size 21i-22? F x 3&-4p. 
On still green Orange leaves, also attacked by Phoma omnivora.
