Lasiodiplodia aquilariae Y. Zhang ter & S. Lin, Mycological Progress 18: 693. 2019.
Index Fungorum: IF 821001; MycoBank: MB 821001.
Colony sporulating on pine needles and SNA. Asexual morph: Conidiomata up to 550 μm diam., stromatic, solitary, immersed and superficial, iron-gray to dark gray. Paraphyses up to 100 μm long, 3 μm wide, hyaline, unbranched, aseptate, becoming up to one-septate when mature. Conidiophores reduced to conidiogenous cells. Conidiogenous cells up to 16 × 3 μm, holoblastic, discrete, hyaline, smooth. Conidia (23–) 25–28 (–29) × 12–16 μm (av. = 26.9 × 14.1 μm, n = 50), L/W ratio = 1.8, hyaline, aseptate, smooth, wall 2 μm thick, ellipsoid to ovoid, both ends broadly rounded, becoming pale brown with septate and longitudinal striationswhen aged. Sexual morph: not observed.
Culture characteristics: Colonies reaching 17 mm diam. on MEA after 2 d in the dark at 28 °C, initially white, becoming ash-gray after 5 days.
Representative isolate: Laos, Vientiane, near the international airport, Aquilaria crassna, Oct. 2012, leg. X. Sun, holotype HMAS 255196, CGMCC 3.18471 (ex-type culture).
Hosts: Aquilaria species (Wang et al. 2019).
Known distribution: Iberian Peninsula, Italy, N. America (Alves et al. 2004), Tunisia (Linaldeddu et al. 2013), Algeria (Smahi et al. 2017).
GenBank Numbers: ITS KY783442; tef1-a KY848600; RPB2 KY848562
Notes: Phylogenetically, Lasiodiplodi aquilariae closely related to all other species of Lasiodiplodia, but the colony grows somewhat slow and conidiomata grow in a dark place.
