MORENOELLA SpCg. 
F. Guaran. i, p. 258 ; Tlieissen, Lembosia-studien, Ann. Myc. xi, p. 425. 
Mycelium superficial, liypliae branched, septate, witli liypliopodia. 
Thyriotliecia dimidiate, inverse, formed of radiating liypliae, typically 
oblong-linear, dehiscing by an irregular longitudinal fissure, asci apara- 
physate, 8-spored. Spores 2-celled, brown. 
Morenoella Oxyanthse Doidge, sp. nov. 
Slides IV, 17 ; XXY, 18 ; XXYI, 17. 
Hypophyllous ; thyriotliecia very densely crowded, forming black or 
rusty brown opaque spots, which are round-irregular, and up to 5 mm. 
diam. Thyriotliecia elongated, attenuated towards each end, often curved, 
400-600 X 250-300 /x, dehiscing by an irregular, longitudinal slit. Hyphae 
not distinct in the centre of the spot, but radiating from the thyriothecial 
mass ; these are more or less densely interwoven, pale, fuscous, slender, 
branched and anastomosing hyphae, 3-3"5 /x thick, with small, globular, 
alternate hyphopodia. Asci aparaphysate, 8-spored, elliptic- ovate, sessile, 
or very briefly pedicellate, very much thickened round the apex, 23-30 x 
13-16 iJi. Spores distichous or conglobate, ellipsoid or sub-clavate, unevenly 
1-septate, the upper cell being shorter and broader, slightly constricted, 
fuscous when mature, 12-16 x 3*5-5 /x.

EcHiDNODELLA Thciss. et Syd.

Like Morenoella, but mycelium non-hyphopodiate. 
Echidnodella Hypolepidis Doidge, sp. nov. 
Shdes XXYIII, 14, 15. 
Epiphyllous, effuse, usually along the midrib of the pinnule, spots 
small and often confluent. Hyphae septate, pale-fuscous, slender, 2-3 fx 
thick, tortuous, abundantly branched and anastomosing ; no hyphopodia. 
Thyriothecia gregarious, often confluent, straight or curved, and not infre- 
quently forked, oblong-ellipsoid, 120-240 x 50-100 fx, dehiscing by a 
n edial, longitudinal slit almost the length of the thyriothecium ; composed
