Lasiodiplodia brasiliensis

Lasiodiplodia brasiliensis M.S.B. Netto, M.W. Marques & A.J.L. Phillips, Fungal Diversity 67: 134. 2014.

Index Fungorum: IF8075258; Facesoffungi: xxxxxx; MycoBank: MB8075258.

Colony sporulating on PNA. Asexual morph: Conidiomata globose, stromatic, solitary, superficial, dark brown to black, uniloculate, thick-walled. Ostiole central, non-papillate. Paraphyses hyaline, cylindrical, aseptate, rounded at apex. Conidiophores not observed or reduced to conidiogenous cells. Conidiogenous cells holoblastic, discrete, hyaline, smooth, thin-walled, cylindrical. Conidia 22.7−29.2 × 11.7−17 μm (av. = 26.01 ± 1.36 × 14.64 ± 1.16 μm, n=50), L/W ratio = 1.8, initially hyaline, aseptate, contents granular, rounded at apex, base mostly truncate, becoming brown and septate with longitudinal striations when aged. Sexual morph: not observed.

Culture characteristics: Colonies reaching 80 mm diam. on MEA after 4 d in the dark at 25 °C. Cardinal temperatures for growth: min 2.04 °C, max < 31.9 °C, opt 25 °C.

Representative isolate: Brazil, Pernambuco, Farm Dan, on Mangifera indica stems, M.W. Marques, holotype URM 85580, CMM 4015 (ex-type culture).

Hosts: Mangifera indica (Netto et al. 2014).

Known distribution: Brazil (Pernambuco, Paraíba, Rio Grande do Norte, Ceará).

GenBank Numbers: ITS JX464063; EF-1α JX464049

Notes: Phylogenetically, Lasiodiplodia brasiliensis is closely related to L. viticola, but can be distinguished based on its morphology. The conidia of L. brasiliensis are longer and wider than those of L. viticola.
