brown, smooth to slightly verruculose, proliferating percurrently, (9–)
13–18(–21) × (3–)4(–5) μm. Conidia solitary, 4–10-septate, straight
to curved, sparsely guttulate, narrowly obclavate, apex subobtuse,
base obconically truncate to long obconically truncate, smooth,
subhyaline, (67–)79–94(–104) × (3–)4(–5)μm, hila unthickened not
darkened.
Culture characteristics: Colonies on MEA reaching 53 mm diam
after 30 d at 24 °C. Colonies circular with feathery margin, flat
to slightly convex, some folding occurs, with a darker radial ring
toward the colony margin, aerial mycelium medium; iron-grey to
olivaceous-grey (surface) and iron-grey (reverse).
Specimen examined: South Korea, Suwon, on leaves of Pilea hamaoi (≡ P. pumila
var. hamaoi), 5 Nov. 2004, H.D. Shin, holotype CBS H-20387, isotype HAL 1860 F,
cultures ex-type CPC 11668 = CBS 126004.
Notes: Singh et al. (1996) provide an account of the
Pseudocercospora spp. present on members of Urticaceae.
Of these, P. crocea is most similar to P. pileae as it also has a
well-developed stroma. Pseudocercospora pileae is distinct from
P. crocea, which lacks stromata and has conidiophores that are
consistently solitary, arising from superficial hyphae.

Leaf spots amphigenous, distinct, 1–3 lesions per leaf, scattered
over the leaf, 3–10 mm diam, pale brown surrounded by a
dark brown to black border. Mycelium internal, consisting of
pale brown, septate, smooth, 2–6 μm diam hyphae. Caespituli
hypophyllous, evenly distributed over the leaf spot, floccose
to punctiform, olivaceous to black. Stromata well-developed,
subimmersed to erumpent, globular, dark brown, 40–100 mm
diam. Conidiophores fasciculate, emerging from the upper cells
of stromata, brown, becoming paler toward the apex, smooth,
0–2-septate, straight to variously curved, guttulate, apex
