Lasiodiplodia hormozganensis Abdollahz., Zare & A.J.L. Phillips, Persoonia 25: 6. 2010.
Index Fungorum: IF516779; Facesoffungi: xxxxxx; MycoBank: MB516779.
Sexual morph: not observed. Asexual morph: Conidiomata up to 950 μm, stromatic, superficial, dark-brown to black, uniloculate, solitary, globose, thick-walled, non-papillate with a central ostiole. Paraphyses up to 83 μm long, 2 – 4 μm wide, hyaline, cylindrical, thin-walled, initially aseptate, becoming up to 1–7 septate when mature, rarely branched, occasionally basal, middle or apical cells swollen, rounded at apex. Conidiophores absent or reduced to a supporting cell. Conidiogenous cells 9–15 × 3–5 μm, holoblastic, discrete, hyaline, smooth, thin-walled, cylindrical. Conidia (15.3 –)18–24(–25.2) × 11–14 μm, 95 % confidence limits = 21.2–21.7 × 12.4–12.6 μm (av. ± S.D. = 21.5 ± 1.9 × 12.5 ± 0.8 μm, l/w ratio = 1.7 ± 0.2), initially hyaline, aseptate, ellipsoid to cylindrical, with granular contents, rounded at apex, base round or truncate, wall < 2 μm, becoming pigmented, verruculose, ellipsoid to ovoid, 1-septate with longitudinal striations.
Culture characteristics: Colonies reaching 83 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, Hormozgan Province, Rudan, on twigs of Olea sp., June 2007, J. Abdollahzadeh and A. Javadi, holotype IRAN 14271F, IRAN 1500C = CBS 124709 (ex-type culture); Hormozgan Province, Rudan-Kheirabad, on twigs of Mangifera indica, June 2007, J. Abdollahzadeh and A. Javadi, IRAN 1498C = CBS 124708; Hormozgan Province, Rudan- Kheirabad, on twigs of Mangifera indica, Mar. 2007, J. Abdollahzadeh and A. Javadi, CJA 57.
Hosts: Olea species (Abdollahzadeh et al. 2010).
Known distribution: Rudan-Kheirabad (Hormozgan Province), Southern Iran.
GenBank Numbers: ITS GU945355; EF-1α GU945343
Notes: Phylogenetically, this species is closely related to L. citricola and L. parva but can be distinguished on average conidial dimensions and length of its paraphyses.
