Colonies amphigenous, mostly epiphyllous, closely scattered, crustose, confluent, dark black, up to
4 mm
in diameter. Hyphae dark brown, substraight to flexuous, branching alternate to unilateral at acute to wide angles, loosely reticulate, cells 20–39 × 5–7 μm. Appressoria opposite, rarely alternate, distantly formed in closed groups of 3 to 4 pairs, mostly just below the end of hyphae, antrorse to subantrorse, bicelled, 16–21 μm long; stalk cells cylindrical to cuneate, 5–7 × 6– 7 μm; head cells subglobose, ovate to oblong, straight to recurved, entire, 9–14 × 7–12 μm. Thyriothecia numerous, closely scattered, initially globose to orbicular, elliptic, elongate to irregular in shape, 314–838 × 240–329 μm, longitudinally fissured at center, sometimes forming
Y
shaped dehiscence at the center, margin crenate to fimbriate with fringed hyphae. Asci numerous, initially globose, obovate to oval, octosporous, 60–73 × 43–59 μm. Ascospores oblong, conglobate, golden yellow, uniseptate, slightly constricted at the septum, 38–43 × 16–18 μm, wall smooth.

Notes:
About 12 species of
Lembosia
have been described on host species of
Syzygium
and
Eugenia
(Song and Hosagoudar 2003, Far and Rossman 2014). The literature survey revealed that, the present species is close to
Lembosia hosagoudarii
Sivan. & R. G. Shivas (2002:163)
;
L. syzygii
Sivan. & R.G. Shivas (2002:160)
and
L. syzygiicola
(Hansf. 1944:115)
Deighton (1978:518)
, known on the host species of
Syzygium
from
India
,
Australia
and
Uganda
respectively (Song and Hosagoudar 2003,
Hosagoudar 2012
, Far and Rossman 2014). However, the new species differs from the related species in having larger appressoria mostly opposite and distantly arranged in groups of 3 to 4 pairs, larger ascospores which are slightly constricted at septum and smooth-walled (
Table 2
).
Lembosia mahabaleshwarensis
can be easily distinguished by arrangement of appressoria and larger, smooth walled ascospores.
This species is associated with
Asteridiella syzygii
Hansf. (1957:50)
and
Asterina jambolanae
Kar & Maity.
