Stachybotrys levispora (Subram.) Yong Wang bis, K.D. Hyde, McKenzie, Y.L. Jiang & D.W. Li, in Wang et al. Fungal Diversity 71:57 (2015)

Memnoniella levispora Subram., J. Indian Bot. Soc. 33: 40 (1954)

Facesoffungi number: FoF01874


Sexual morph: Undetermined. Asexual morph: Colonies on natural substrate, gregarious, scattered, superficial, like black powder, bouquet-like. Conidiophores (37–)49–54(81–) μm long, 3–4μm wide at the base, 5–7μm wide at swollen apex, unbranched, straight or flexuous, macronematous, phalidic, verrucose, dark grey to black at lower half, thick-walled, 1–3-septate, Conidiogenous cells 6–8×3–5 μm diam. (x̄ = 6×4μm), monophialidic, pigmented, discrete, short narrow at the apex, clavate, ellipsoidal or broadly fusiform. Conidial heads at first globose, hyaline, forming on conidiogenous cells. Conidia 4–6×4–6 μm (x̄ = 5×5μm n= 30), globose, blackish brown to black, catenate, basipetal, numerous, smooth, hemispherical, aseptate, symmetric.


Culture characteristic: Conidia germinating on PDA after 24 h. Germ tubes produced from germ pores. Colonies growing on MEA reaching 16–21 mm diam. after 3 weeks in the dark at 25 °C, (x̄ = 18.3 n =5), crenated, flat or effuse, fluffy, medium sparse, aerial, white (4A1) from above, pale yellowish (4A3) from below.


Habitat: Known to inhabit dead stem (Subramanian 1954) and dead twigs and dead branch of T. grandis.


Known distribution: India (Subramanian 1954) and Thailand.

Material examined: Thailand, Chiang Rai Province, Mae Chan District, on dead twig of T. grandis, 7 September 2012, N. Tangteerasunun, MFLU 15–3425, living culture MFLUCC 12–0561, MKT 077, ICMP, GenBank Accession No: ITS: KU144931, LSU: KU764714, SSU: KU712478, TEF1: KU872752, Chiang Rai Province, Mae Chan District, on dead twig of T. grandis, 3 March 2013, M. Doilom, MFLU 15–3429, living culture MFLUCC 13–0469, MKT 110/3, GenBank Accession No: ITS: KU144930 LSU: KU764715, SSU: KU712480, TEF1: KU872753; Uttaradit Province, Pichai District, on dead branch of T. grandis, 11 October 2014, S. Boonmee & S. Konta, MFLU 15–3443, living culture MFLUCC 14–1149, MKT 173/1, GenBank Accession No: ITS: KU144934 LSU: KU764716.

Notes: The MegaBLAST search of the NCBI GenBank nucleotide database for ITS sequence data of isolate MFLUCC 12–0561 (accession number KU144931) Identities = 494/494 (100 %) showed similarity to Memnoniella levispora (Menlev3308, GenBank KF626495). However, the sequences are unpublished and no ex-type sequence data of St. levispora is available in GenBank (Wang et al. 2015). Based on morphological features, they are similar to St. levispora (Subramanian 1954; Ellis 1971; Wang et al. 2015), and therefore, the collections in the present study are designated as St. levispora.
