Aecidium Plantaginaceae 195 



I. Aecidia on both surfaces of leaves, but mostly on under, bullate, 

 brownish, resembling dotted discs, often confluent, at first entirely 

 enclosed, ultimately opening irregularly by small pore, 1-1 J mm. ; 

 peridial cells hyaline, loosely adherent, subglobose, elliptic or 

 lozenge-shaped when united, with striated margin, 25-30 p. 



Aecidiospores orange-yellow, subglobose to elliptic, 16-20 u. diam 

 or 19-22 x 14-16 /u.

This species causes thickening and distortion of the leaves. It is quite 

 distinct from A, veronicae Berk., of which there is a portion of the original 

 material in the National Herbarium, Melbourne. The latter forms a regular 

 cup with fimbriate margins, while the former only opens by a minute pore. 

 The spores are also quite different.

I. Aecidia numerous, crowded, semi-immersed, on under-surface of leaf 

 arid a few scattered on upper surface, J mm. diam.; pseudo- 

 peridia cup-shaped, becoming discoloured and dark-brown with 

 age, with fimbriate margins ; peridial cells, oblong to angular, with 

 very broad striated margin, average 32 X 2o p. 



Aecidiospores dark yellow, variously shaped, ellipsoid, oblong or 

 angular, with finely -granular contents, 24-30 x 16-20 ju ; epispore 

 hyaline, finely verrucose, about 2 p. broad.

There is an old specimen in the National Herbarium which had been 

 submitted to Berkeley by the late Baron von Mueller. There are plenty of 

 spores still in the cups, but probably the thoroughly mature ones have fallen 

 away.
