Lasiodiplodia citricola Abdollahz., Zare & A.J.L. Phillips, Persoonia 25: 4. 2010.
Index Fungorum: IF516777; Facesoffungi: xxxxxx; MycoBank: MB516777.
Sexual morph: not observed. Asexual morph: Conidiomata up to 2 mm diam., stromatic, superficial, dark brown to black, uniloculate, solitary, globose, thick-walled, non-papillate with a central ostiole. Paraphyses up to 125 μm long, 3–4 μm wide, hyaline, cylindrical, thin-walled, initially aseptate, becoming up to 1– 5 septate when mature, occasionally branched, rounded at apex, occasionally basal, middle or apical cells swollen. Conidiophores absent or reduced to a supporting cell. Conidiogenous cells 11–16 × 3–5 μm, holoblastic, discrete, cylindrical, hyaline, smooth, proliferating per currently to form one or two indistinct annellations. Conidia (20–)22–27(–31) × (10.9–)12–17(–19) μm, 95 % confidence limits = 24.1–24.9 × 15–15.7 μm (av. ± S.D. = 24.5 ± 0.2 × 15.4 ± 1.8 μm, l/w ratio = 1.6 ± 0.2), hyaline, aseptate, contents granular, smooth, thick-walled, oblong to cylindrical, both ends broadly rounded, rarely becoming brown and septate with longitudinal striations when aged.
Culture characteristics: Colonies reaching 85 mm on MEA after 2 d in the dark at 25 °C. Cardinal temperatures for growth: min 10 °C, max < 35 °C, opt 25−30 °C.
Representative isolate: Iran, Gilan Province, Chaboksar, on twigs of Citrus sp., June 2007, J. Abdollahzadeh and A. Javadi, holotype IRAN 14270F, IRAN 1522C = CBS 124707 (ex-type culture); Mazandaran Province, Sari, on twigs of Citrus sp., June 2007, A. Shekari, IRAN 1521C = CBS 124706.
Hosts: Citrus species (Abdollahzadeh et al. 2010).
Known distribution: Chaboksar (Gilan Province), Sari (Mazandaran Province), Northern Iran.
GenBank Numbers: ITS GU945354; EF-1α GU945340
Notes: Phylogenetically, Lasiodiplodia citricola is closely related to L. parva, but conidia of L. citricola are longer and wider than those of L. parva. This species produces a pink pigment in PDA cultures at 35 °C.
