This fungus forms large raised galls about 1 mm. high; on both sides of the leaf, 
they are circular or oval and up to 1 cm. diam. The stroma breaks through the epidermis, 
forming a number of little furrows which are arranged in numerous concentric circles. 
The vegetative stroma extends perpendicularly downwards into the gall tissue, filling the 
intercellular spaces with smooth, light brown hyphae 33-4 thick; before they break 
through the epidermis these become collected together and form a thick compact weft, 
on which are formed in groups the narrow, almost free loculi. These in section are 135 u 
high and 100 » diam., the stromatic base of each group being 160-240 u thick. Asci basal, 
aparaphysate, broadly clavate to oval, very briefly pedicellate, 58-68 u x 30-40 u; spores 
brown, tristichous, oblong, 30 2 x 6-8 uv, four-celled, constricted in the middle, rounded 
at both ends, straight.

On leaves of Myrsine melanophleos, Kentani, 3.4.12, Pegler [2206]; May, 1913,

Stromata hypophyllous, black, punctiform, not more than 0-5 mm. diam., attached 
to the leaf by a central foot which breaks out thr ugh a stoma. The central foot gives 
rise to a thick basal cushion of sterile plectenchyma, on which are borne the small bolster- 
shaped ascostroma and one or two sub-spherical pycnidia, both being flattened laterally 
by contact. The stroma is often surrounded by a short sparse fringe of fuscous hyphae, 
which are septate and 3-35) thick. Ascostroma 300-430 u ` 200-270» and about 
80-90 » high, unilocular ; wall consisting of polyhedral plectenchyma. Asci paraphysate, 
oval to clavate, very briefly pedicellate, 60-70» x 23-27%; paraphyses not numerous, 
filiform, excecding the asci. Spores distichous, hyaline, 3-septate, clavate to ellipsoid, 
not constricted, 27-30% «x 9-10 yu. Pyenidia 160-200 1 diam. ; conidia very numerous, 
minute, bacilloid.

Stromata usually hypophyllous, less frequently epiphyllous, very numerous, but not 
large, up to 2 mm. diam. Often larger, irregular stromata are formed by confluence. 
In the intercellular spaces under the epidermis the hyphae are colourless and closely 
packed, passing over into a darker coloured mass of round-polygonal cells 5-6-5 u diam. 
This layer of dark, thick-walled cells is rather irregular and here and there penetrates 
deeper into the leaf tissues. From this stromatic base arise very numerous, closely 
crowded, cylindrical or club-shaped bodies 200-240 » high, 96-160» thick at the base
