336 DECADES OF FUNGI. 
This species has exactly the habit of a Spheria of the 
Cespitose tribe; but there is no real perithecium, and 
though the tubercles sometimes contain but a single cell, 
there are generally a great many cells, and the species must 
therefore be referred to Dothidea. Dr. Montagne had pro- 
posed for it the name of D. pSseudo-spheria; but as the 
Philippine Island plant proved to be the same species, the 
original specific name has been retained.

Forming on the upper surface of the leaf, exactly orbicular 
planesometimes confluent spots 4 ofan inch broad, of a shining 
pitchy black, and rough with the ostiola. Perithecia very 
small covered conico-hemispherical depressed shining 
scarce ¿ of a line in diameter pierced above with a scarcely 
perceptible pore. Asci short obtuse containing eight bilo- 
cular oblong sporidia which are constricted in the middle 
and have a single oil-globule in each division. These are at 
first hyaline but at length become brown and are twice as 
long asat first. Paraphyses linear slightly branched. Amongst 
the paraphyses are found abortive asci which present exactly 
the appearance of the young spores of a Diplodia. On the E. 
under side of the leaf there is a little depression answer ——— 
to each spot. age 
This species which is a very beautiful one varies €x- 
tremely in size. It is only in the finest patches that perfect 
asci have been found. The same leaves are sprinkled with 
Micropeltis applanata, Mont. in fine condition, a species 
found hitherto only in Cuba. |
