Meliola palmicola Wint. 
G-aillard, Le G-enre Meliola, p. 101 
Spots orbicular, often confluent, 1-15 mm. diam., black, with an irregular 
margin. Mj^celium brown, branching, branches opposite, anastomosing. 
Hyphae somewhat sinuous, about 10 thick, cells 24-28 /x long. Capitate 
hyphopodia alternate, stipitate, basal cell 10-25 /x long, non- septate in 
younger parts of mycelium and about 10 long, in central parts of colony 
often pluricellular and up to 25 /x long ; terminal cell globular to ovoid, 
often bent laterally and more or less lobed, 16-20 x 10-11 /a. Mucronate 
hyphopodia fairly numerous, on separate branches, opposite, ampulliform, 
17-20 X 8-10 fji. Mycelial setae very numerous, straight, erect, opaque, 
black, 400-500 /x long, about 10 thick at base, tapering slightly towards 
apex ; apex sometimes simple, more often divided into 2-3 simple or bifid 
branches ; more rarely there are 4 or 5 unilateral branches. Perithecia 
fairly numerous in centre of colony, globular, than depressed, 180-250 /x 
diam., surface minutely verrucose. Asci ovoid, 2-4 spored, about 54-56 x 
30-35 fi. Spores 4-septate, slightly constricted at the septa, elliptic, rounded 
at both ends, 48-55 x 20-22 /x.

Mycelium mostly epiphyllous, thin, spreading, black, effuse, not forming 
definite spots, often following the primary veins of the leaf. Hyphae 
fuscous, septate, 5-7 /x thick ; branches mostly alternate ; cells of hyphae, 
20-36 /X long, mostly 20-25 /x. Capitate hyphopodia alternate, 16-24 /x long, 
basal cell minute, capitate cell clavate, 10-12 /x broad. Mucronate hypho- 
podia, opposite or unilateral up to 20 /x long ; narrowing above and often curved. 
Mycelial setae scattered, often more numerous around perithecia, 200-275 /x 
long, 5-8 /X thick, not tapering towards apex, abruptly geniculate near base, 
with 2-5 incisions or teeth on the blunt apex ; more or less translucent. Peri- 
thecia scattered, few, globose, tuberculate, black, 180-240 /x diam. Asci ovate, 
very briefly stipitate, 2-spored. Spores oblong or oblong-cylindrical, con- 
stricted at the septa, rounded at both ends, brown or fuscous, 40-43 x 16-18 /x.
