Meliola Peglerae Doidge. 
Epiphyllous, sub-crustaceous, black, forming black orbicular colonies 
1-3 mm. diam. which form larger spots by becoming confluent. Hyphae 
frequently septate, formed of cells 8-14 x 7-9 /x, colour Saccardo's umber 
(E. XXIX). Branches anastomosing. Capitate hyphopodia numerous^ 
alternate, or unilateral, briefly stipitate, appressed towards the hyphae ; basal 
cell 7 X 4-7 /X ; terminal cell larger, obovoid, straight or more frequently bent 
backward at the tip (almost retort-shaped) 14-18 x 7-11 /x. Mucronate 
hyphopodia few in number, opposite, ampulliform, 14-22 X 7 /x. Mycelial 
setae none. Perithecia crowded together in the centre of the colony, black, 
126-233 jjL diam. Superficial cells mammillate. Asci 2-4-spored, evanescent,. 
Spores oblong, rounded at both ends, 4- septate, slightly constricted at the 
septa, 29-43 x 16-18 /x.

Amphigenous, but mostly epiphyllous ; forming small, black, thinly 
carbonaceous colonies 1-3 mm. in diam., sometimes very numerous and 
then confluent. Hyphae 7-8 /x thick, composed of cells 18-22 /x long, sinuous, 
tawny olive (E. XXIX). Capitate hyphopodia alternate, about 25 /x long, 
stipitate ; terminal cell rounded, truncate or somewhat lobed, averaging 
14-16 X 10-11 /X. Mucronate hyphopodia not so numerous, opposite, only 
slightly paler, 14-18 /x long, ampulliform, with a short neck. Setae none. 
Perithecia scattered, black, globular, 200-250 /x diam., the surface being 
covered with conical or horn-shaped unicellular processes, 60 x 15 /x. Asci 
ovoid briefly pedicellate, 2-spored. Spores 4-septate, constricted at the 
septa, elliptical, rounded at the extremities, similar in colour to the 
mycelium, 35-38 x 13-15 /x.
