Ciri dan struktur
Associated with leaf spots on Cycas sp. (Cycadaceae). Sexual morph Undetermined. Asexual morph Coelomycetous. Conidiomata (60–)100–160 μm high, (60–)135–200 μm diam., pycnidial, visible as black dot on host surface, scattered to clustered, solitary to gregarious, semi-immersed to erumpent, uni-loculate, subglobose to ampulliform, or irregular in shape, ostiolate, with minute papilla. Conidiomata walls 10–20(–30) μm wide, composed of 4–5 cell layers, of brown to dark brown pseudoparenchymatous cells, of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells (3.5–)4.5–8 × 4–8(–10) μm (\(\bar{x} \) = 6.4 × 5.7 μm, n = 30), ampulliform to broadly conical, gradually tapering toward the apex, holoblastic, phialidic, hyaline, smooth-walled, with periclinal wall thickening, arising from the inner cavity of the conidioma wall. Conidia (10–)12–14(– 16) × 3–5 μm (\(\bar{x} \) = 12.9 × 3.9 μm, n = 50), pale brown to light yellowish, oblong to ellipsoidal, or subcylindrical, (0–)1–2-septate, truncate to obtuse base, with obtuse apex, not constricted at the septa, smooth-walled. Culture characteristics: Colonies on PDA reaching 50–52 mm diam. after 3 weeks at room temperature (20–30 °C). Colony dense, irregular in shape, flattened, surface slightly smooth, edge undulate, with entire margin, cottony to floccose, slightly sparse near the margin; from above, white to cream, slightly radiated outwards colony; from below, slightly radiating, cream at the margin, pale brown to yellowish-brown at the centre, sectering with golden brown; not producing pigmentation on agar medium.

Notes: In the NCBI BLASTn search of ITS sequences, Phaeosphaeria cycadis most closely matches P. acaciae Tennakoon et al. with 99% similarity. Multigene phylogenetic analyses based on a combined LSU, SSU, TEF1-α and ITS sequence dataset show that P. cycadis forms a sister lineage with P. acaciae with high support (100% ML and 1.00 BYPP; Fig. 29). The ITS gene could not clarify the novelty of P. cycadis in this study as the species is not significantly different from P. acaciae in a comparison of ITS sequences (5/452 bp). Phookamsak et al. (2014b) mentioned that Phaeosphaeria contains species complexes that cannot be resolved based only on the ITS gene and that a combination of protein coding genes, such as TEF1-α and RPB2, is necessary to clarify species in this genus.
