Dothiorella plurivora (Abdollahz., Javadi & A.J.L. Phillips) Tao Yang & Crous, in Yang, Groenewald, Jami, Cheewangkoon, Abdollahzadeh, Lombard & Crous 2016

Index Fungorum number: IF817676         Facesoffungi number: FoF05785



Sexual morph: Undetermined. Asexual morph: Coelomycetous. Conidiomata 155–260 μm diam., stromatic, superficial, unilocular, glabrous, brown to black, globose to subglobose, papillate. Ostiole central, short, lined with periphyses. Wall of conidiomata 20–45 μm membranaceous, composed of dark brown, or brown to hyaline cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 5–9 × 1.5–5 μm (x̄ = 7.5 × 3.5 μm, n = 30), enteroblastic, phialidic, cylindrical to subcylindrical, hyaline, smoothwalled, arising from the inner layers of conidioma. Conidia 14–22 × 5–10 μm (x̄ = 18 × 8 μm, n = 50), ellipsoidal to oval, hyaline when young, becoming to brown when mature, smooth-walled, guttulate, 1-septate.


Culture characteristics: Ascospores germinating on PDA (potato dextrose agar) within 2 days at 23 °C. Sporulation after 1 week, colony 2 cm diam. gray from above and reverse, with white mycelia radiating outwards, with irregular form of margin, filamentous mycelium, with rough surface.


Material examined: China, Yunnan Province, Kunming, Songhuaba Lake; on dead wood, 3 September 2017; S.K. Huang (KUN HKAS 99572), living culture (KUMCC 18-0013).


GenBank Accession No: ITS: MK459467, LSU: MK459468.


Notes: Spencermartinsia plurivora has been isolated from soil in Iran (Abdollahzadeh et al. 2014). Multi-gene analysis showed that Spencermartinsia to have close affinities with Dothiorella (Phillips et al. 2013; Slippers et al. 2013). Therefore, Yang et al. (2016b) placed Spencermartinsia as a synonym of Dothiorella. In phylogenetic analysis of Dothiorella, our strain clusters with the ex-type strain of Dothiorella plurivora (IRAN 1557C). Dothiorella plurivora is characterized by 7–10 × 3–5 μm conidiogenous cells and ellipsoid to ovoid, brown, 1-septate conidia (20–25 × 10–13 μm) (Abdollahzadeh et al. 2014). Morphological similarities reveal it is similar to our taxon.
