Figure Fig. 1 5-day-old colony on PDA Fig. 2 Xylaria curta group. a, d, e, f. Conidiophores, conidiogenous cells and conidia. b. Sterile base of the stromata. c. Stromata formed on PDA. g. Conidia (Bars= 5 μm, unless otherwise specified)
Colonies Colonies on PDA attaining 52-mm in 5 days at 25 °C, white, cottony near the center, forming rope-like strands toward the margin, turning black with age.
Stromata Stromata formed on PDA after 3 wks, cylindrical, up to 1 cm high. Basal parts sterile, dark brown, composed of textura epidermoidea. Upper parts covered with dry, brownish grey conidia,
Conidiophores Conidiophores pale brown, repeatly branched, arising from stroma or aerial hyphae.
Conidiogenous cells Conidiogenous cells mostly terminal, hyaline or pale brown, cylindrical, with several denticulate conidiogenous loci.
Conidia Conidia obovoid to obclavate, hyaline, with a acute or slightly truncated base, (6.5–)7–8 × 3.5–4(–4.5) µm.
