diametro unilocularia. Loculli ellipsoidei, 300-350  diametro, 100-120 u alti; clypeo — 
atro, opaco, 30-40 y crasso. Asci paraphvsati, cylindracei v. ellipsoidei, octospori, sessiles,

53. Dictyochorella Andropogonis n. sp. 
On leaves of Andropogon nardus, Tug la Valley, near Goodoo, Natal, 16.5.20, Doidge 
[14104]. 
Stromata thickly strewn on the leaf surface, small, oval to elliptic, 4—1 mm. long, 
visible on both surfaces, slightly convex, loculi mostly opening towards the upper leaf 
surface ; often a number of stromata arising close together become confluent and form 
streaks up to 5 mm. long in which the separate stromata can still be distinguished. Stromata 
with one or few locul. Loenli occupying the whole of thickness of leaf, 190- 240 v. diameter 
' 160-190 u high. Clypeus over apex of locul black, di about 30 u thick, extending 
fonpidarably bevond loculus on each side : basal clypeus 20-25 u thick ; when the loculus 
does not reach basal clypeus. then the intervening space is filled with brown hyphae ; lateral 
walls (and basal where there is no clypeus) up to 20 y thick and composed of brown compact 
angular cells. Stylospores brown, oval, elliptic or pyriform; with a central (2) vacuole, 
8-10 x 8-4 yu. Asci paraphvsate, cvlindrical, rounded at apex, eight-spored, 80-90 x 
12-13 u. Spores distichous or obliquely monostichous, with three or occasionally four 
transverse septa, constricted at septa, tapering towards rounded at ends, two central cells 
broader than terminal ones and one or both with a somewhat oblique longitudinal septum, 
15-17 x 6-7 p, fuscous-olivaceous, sometimes only one central cell has a septum and it 
is then broader than the other.

Stromata oval, about 600 vy long, 300-400 p. broad, cr subcircular 4-1 mm. diameter, 
very irregular in outline, usually visible on both sides of the leaf, gen only on one 2E 
and surrounded by a small, pale ring, later forming elliptic groups 3-1 cm. long and 3 4 cm. 
broad. A dark epidermal clvpeus is developed in both leaf surfaces. Locuh, flattened= 
spherical, often irregular in shape, mostly 170 u diameter, 120-130 u high, locular wall 
composed of delicate, light brown hyphae, fusing at the apex with the clypeus, 12-14 u 
thick. Asci cylindrical, parietal, paraphysate, briefly pedicellate, 52-60 x 7-8 u. Spores 
obliquely monostichous or subdistichous, oblong, club-shaped, fuscous, rounded at both
