Phyllosticta capitalensis

Ciri dan struktur

Leaf endogenic and associated with leaf spots. Asexual morph: Conidiomata pycnidial, mostly aggregated in clusters, black, erumpent. In MEA, cultures exuded colourless to opaque conidial masses, appeared on pycnidia after 10 days or longer. Pycnidial walls of multilayered, textura angularis, brown to dark brown, up to 35 μm thick; inner walls hyaline. Conidiophores subcylindrical to ampulliform, frequently reduced to conidiogenous cells or branching from a basal supporting cell, coated in mucoid layer, 8.0–14.0 × 3.0–5.0 μm. Conidiogenous cells terminal, subcylindrical to ampulliform, hyaline, smooth, 8.0–11.0 × 3.0–4.5 μm. Conidia 9.0–12.5 × 5.0–7.0 μm, mean ± SD = 10.6 ± 0.9 × 6.2 ± 0.5 μm, solitary, hyaline, aseptate, thin and smooth walled, coarsely guttulate or with a single large central guttule, ovoid, ampulliform, ellipsoidal to subglobose, enclosed in a thin mucoid sheath, 1.3–2.7 μm thick and bearing a hyaline, apical mucoid appendage, 3.0–8.5 × 1.0–1.5 μm, flexible, unbranched, tapering towards an acutely rounded tip. Spermatia hyaline, smooth, guttulate to granular, bacilliform, 6.0–8.2 × 1.3–2.0 μm, occurring in conidioma with conidia. Sexual morph: Ascomata shape and wall like those of the conidiomata. Asci bitunicate, hyaline, clavate to broadly fusoid-ellipsoid, with visible apical chamber, 2 μm diam., 45–85 × 9–13 μm. Ascospores bi- to multiseriate, hyaline, smooth, granular to guttulate, aseptate, straight, rarely curved, widest in the middle, limoniform with obtuse ends, 15–18 × 6–7 μm. Colonies on PDA occupying an entire 90 mm Petri dish in 14 days at 25 °C in darkness, with a growth rate of 6.0–6.5 mm/day, greenish-black in obverse and reverse.

Habitat dan peran ekologis

Colonies on PDA occupying an entire 90 mm Petri dish in 14 days at 25 °C in darkness, with a growth rate of 6.0–6.5 mm/day, greenish-black in obverse and reverse. Colonies on MEA 82–86 mm in diameter after 14 days at 25 °C in darkness, with a growth rate of 5.7–6.2 mm/day, undulate at edge, white to grey white in obverse and reverse, with moderate aerial mycelia on the surface, with black, gregarious conidiomata. Based on morphological features, Hennings (1908) described Phyllosticta capitalensis and Glienke et al. (2011) added molecular data. The holotype (CBS 128856) of P. capitalensis was collected from Stanhopea graveolens (Glienke et al. 2011). In our current study, two isolates (SAUCC 210144, SAUCC 210148), collected from diseased leaves of Rhapis excelsa, cluster in the P. capitalensis clade (Fig. 1). Although four other species are also in this clade, we consider these two isolates as P. capitalensis, based on their morphological characters, such as granular to guttulate ascospores (15–18 × 6–7 vs. 15–17 × 5–6 μm), subcylindrical to ampullate conidiogenous cells (8.0–11.0 × 3.0–4.5 vs. 7–10 × 3–5 μm), ellipsoidal to subglobose conidia (9–12.5 × 5–7 vs. 11–12 × 6–7 μm) and hyaline, apical mucoid appendages (3–8.5 × 1–1.5 vs. 6–8 × 1–1.5 μm).
