Lasiodiplodia gilanensis

Lasiodiplodia gilanensis Abdollahz., Zare & A.J.L. Phillips, Persoonia 25: 5. 2010.

Index Fungorum: IF516778; Facesoffungi: xxxxxx; MycoBank: MB516778.

Sexual morph: not observed. Asexual morph: Conidiomata up to 940 μm, stromatic, superficial, dark brown to black, covered with dense mycelium, mostly uniloculate, solitary, globose, thick-walled, non-papillate with a central ostiole. Paraphyses up to 95 μm long, 2–4 μm wide, hyaline, cylindrical, thin-walled, initially aseptate, becoming up to 1–3 septate when mature, rarely branched, rounded at apex. Conidiophores absent or reduced to a supporting cell. Conidiogenous cells 11–18 × 3–5 μm, holoblastic, discrete, hyaline, smooth, thin-walled, cylindrical. Conidia (25.2–)28–35(–38.8) × (14.4–)15–18(–19) μm, 95 % confidence limits = 30.6–31.4 × 16.5–16.7 μm (av. ± S.D.=31 ± 2.4 × 16.6 ± 1 μm, l/w ratio = 1.9 ± 0.2), hyaline, aseptate, ellipsoid to ovoid, with granular content, rounded at apex, base mostly truncate, 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, Gilan Province, Rahimabad-Garmabdost, on twigs of unknown woody plant, June 2007, J. Abdollahzadeh and A. Javadi, holotype IRAN 14272F, IRAN 1523C = CBS 124704 (ex-type culture); Gilan Province, Rahimabad-Garmabdost, on twigs of unknown woody plant, June 2007, J. Abdollahzadeh and A. Javadi, IRAN 1501C = CBS 124705.

Hosts: Unknown.

Known distribution: Rahimabad-Garmabdost (Gilan Province), Northern Iran.

GenBank Numbers: ITS GU945351; EF-1α GU945342

Notes: Phylogenetically, L. gilanensis is closely related to L. plurivora, but can be distinguished on average conidial dimensions. This species produces a pink pigment in PDA cultures at 35 °C.
