Lasiodiplodia iraniensis

Lasiodiplodia iraniensis Abdollahz., Zare & A.J.L. Phillips, Persoonia 25: 8. 2010.

Index Fungorum: IF516780; Facesoffungi: xxxxxx; MycoBank: MB516780.

Sexual morph: not observed. Asexual morph: Conidiomata up to 980 μm, stromatic, superficial, dark brown to black, uniloculate, solitary, globose, thick-walled, non-papillate with a central ostiole. Paraphyses up to 127 μm long, 2–4 μm wide, hyaline, cylindrical, thin-walled, initially aseptate, becoming up to 1–6 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 9–16 × 3–5 μm, holoblastic, discrete, hyaline, smooth, thin-walled, cylindrical. Conidia (15.3–)17–23(–29.7) × 11–14 μm, 95 % confidence limits = 20.6–20.8 × 13–13.1 μm (av. ± S.D. = 20.7 ± 2 × 13 ± 0.9 μm, l/w ratio = 1.6 ± 0.2), initially hyaline, aseptate, subglobose to subcylindrical, with granular content, both ends rounded, wall < 2 μm, becoming pigmented, verruculose, ellipsoid to ovoid, 1-septate with longitudinal striations.

Culture characteristics: Colonies reaching 80 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, Bandar Abbas, Geno mountain, on twigs of Salvadora persica, Mar. 2007, J. Abdollahzadeh and A. Javadi, holotype IRAN 14268F, IRAN 1520C = CBS 124710 (ex-type culture); Golestan Province, Gorgan-Toshan, on twigs of Juglans sp., June 2007, A. Javadi, IRAN 1502C = CBS 124711.

Hosts: Salvadora persica (Abdollahzadeh et al. 2010).

Known distribution: Hormozgan & Golestan Provinces, Southern and Northern Iran.

GenBank Numbers: ITS GU945348; EF-1α GU945336

Notes: Phylogenetically, L. iraniensis is clearly distinct from other species, but is most closely related to L. theobromae, but can be distinguished on average conidial dimensions. This species produces a pink pigment in PDA cultures at 35 °C.
