UREDINIA abaxial, distributed over the whole surface, small, occasionally in large irregular groups, pulverulent, slightly erumpent, reddish brown in color.
Sexual state: Ascomata 200-365 x 240-425 [micro]m ([bar.x] = 315 x 275 [micro]m, n = 10), immersed, initially erumpent becoming superficial, scattered, depressed-globose, some flattened at the base, opening a disc-like lid of brown prismatic cells with setae.
Initially Graphyllium was placed in the Hypodermiaceae by Clemencet (1901) and described as "Hysterothecium innate, then erumpent, linear, simple, membranaceous-plectenchymatous, black; asci ovoid or cylindrical-clavate, 8-spored; spores brown, elliptical to oblong, with transverse- and longitudinal septa, but not muriform; pseudoparaphyses simple or branched, septate, forming an epithecium" Later Barr [17] transferred the genus to order Pleosporales and referred to Phaeosphaeriaceae.
Infection sites were evident as small chlorotic flecks on the leaf, and when these developed a distinct orange color and the overlying epidermis became erumpent, the uredinium was considered formed.
Hysterothecia gregarious, erumpent, superficial, straight to flexuous, irregular in shape especially when crowded, 0.47-1.80 x 0.28-0.57 mm, lips more or less open exposing a narrow red disc; pseudoparaphyses hyaline, abundant, filiform, branched, longer than asci; epithecium ferrugineous to red-brown, 3 % KOH staining purple; asci cylindrical-claviform, (4-)8-spored, 110-180 x 14-20 [micro]m; ascospores reddish brown, uniseriate to biseriate, muriform, appearance not parenchymatic, with 4-6 transverse and 1 longitudinal septa, ellipsoid, constricted at the median septum, 16-26(-28) x 8-10 [micro]m.
Hysterothecia single or gregarious, erumpent, superficial, straight to flexuous, surface usually striate, 0.4-2 x 0.2-0.4 mm; pseudoparaphyses hyaline, abundant, filiform, branched, longer than asci; epithecium compact; asci clavate to cylindrical, 8-spored, (55-)70-170 x 10-18 [micro]m; ascospores yellow-brown to reddish brown, uniseriate to partially biseriate, muriform, not parenchymatic, with [3-5(-7)] transverse and 1 longitudinal septa, ellipsoid to obovoid, sometimes slightly inequilateral, constricted at the median septum, (12-)15-24(-26) x (5-)6-10(-11) [micro]m.
Hysterothecia gregarious, erumpent, superficial, straight, 0.21-0.56 x 0.12-0.16 mm; pseudoparaphyses hyaline, abundant, filiform, branched, longer than asci; epithecium ferrugineous to redbrown; asci cylindrical, 8-spored, 100-120 x 12-14 um; ascospores reddish brown, uniseriate to partially biseriate, muriform, not parenchymatic, with (1-2-)3 transverse and 1 longitudinal septa (?), obovoid, constricted at the median septum, lower cell conical and lighter than the upper ones, 10-14 x 4-6 [micro]m [18-20 x 8-10 [micro]m, fide Spegazzini (1912)].
