Ciri dan struktur
Associated with canker on twigs of Hevea brasiliensis. Asexual morph: Conidiomata acervular, solitary, erumpent through the outer periderm layers of host, scattered, surface tissues above slightly dome-shaped, black, velvety, formed of brown cell, thick-walled textura angularis, 145–540 µm diam. Conidiophores short, cylindrical, apically pale brown, paler at the base, smooth, septate, branched at the base, arising from basal stroma, 22–37 × 4–8 μm (x ‒ = 28.5 × 5.6 μm, n = 15). Conidiogenous cell annellidic, integrated, terminal, cylindrical, medium brown, truncate apex, with 1-3 slightly percurrent proliferations, 6–17 µm long (x ‒ = 10.7 μm, n = 20). Conidia curved, clavate to fusiform, dark brown, smooth-walled, 4–6-pseudo-septa, sometimes with apical and basal cells darker than other cells, rounded or sometime truncate at apex, truncate and black at the base, (40–)43–53(–68) × (14–)15–20 μm (x ‒ = 48.7 × 17.3 μm, n = 85). Appressoria hyaline, globose to sub globose, thick-walled, 4–11 μm wide (x ‒ = 7.1 μm, n = 20). Conidia germinated on MEA within 24 h with germ tubes produced from one or both end cells, mostly from basal cell of conidia. Colonies on MEA reaching 20–25 mm diam. after 4 weeks at 25–30 °C, colonies circular, medium dense, cottony, margin wavy, superficial, slightly effuse, radially striated; colony from above, white, edges with more aerial mycelium than centre in the beginning and later become white grey, smooth with edge entire; from below: white to cream at the margin, yellowish-green in the centre in the beginning and later become dark green; not producing pigmentation in agar.

Colonies on PDA reaching 10–15 mm diam. after 4 weeks at 25–30 °C, colonies circular, medium dense, cottony, slightly effuse, dark green with brown aerial mycelium on surface; not producing pigmentation in agar. Conidial masses were observed in PDA culture after 6 months at 25–30 °C. Mass of conidia dark brown to black, extruding on colony or tip of mycelium (Figure 2 q, r). Mycelium superficial and immersed, dark brown, hyphae branched, septate, constricted at septa, thick, smooth-walled (Figure 2 s).
