305. Depazea Mappa, n. s.; maculis e plagis variecoloribus subcon- 
centricis fusco-limitatis formatis; peritheciis olivaceis ; ascis subelon- 
gatis, sporidiis oblongis sublanceolatis hyalinis. (Tas. I. fig. 3.) 
Has. Caripi. On leaves of some unknown plant. ; 
Forming patches an inch or more in diameter, consisting of more or 
less concentric irregular areæ, those in the centre mostly whitish, the 
others presenting one or more shades of more or less bright red-brown ; 
each area being strictly defined by a brown, wavy, somewhat diffused 
line. The whole presents the appearance of a coloured map. Peri- 
"thecia punctiform, olive, with a white speck in the centre. Asci at 
first short, at length slightly elongated, lanceolate ; sporidia oblong, 
inclining to lanceolate, with one side more strongly curved, hyaline. 
Occasionally two or more perithecia are connected by a greenish 
substance. 
A very pretty species, marked by several distinct characters. A 
single specimen exists in the collection of a variety or allied species, 
growing upon some larger leaves, evidently congeneric with those on 
which D. Mappa is developed. The spots are much larger, consisting 
of a larger number of more strictly concentric rings, which are of a 
more uniform wood-colour. Unfortunately, the spots are without 
perithecia.
