Neoleptosporella camporesiana

Neoleptosporella camporesiana R.H. Perera & K.D. Hyde, in Hyde et al., Fungal Diversity 100: 219 (2020)

Index Fungorum number: IF556898         Facesofungi number: FoF 06962

Etymology: Named after the collector Erio Camporesi.

Holotype: MFLU 19-0978


Saprobic on a plant stem. Sexual morph: Appearing as shiny black, raised dome-shaped spots, with a central short papilla. Ascomata 210–300 μm high, 705–980 μm diam. (x̄ =250 × 800 μm, n=10), solitary or aggregated, immersed beneath small clypeus appearing as a disc around the neck, uni-loculate, subglobose to depressed globose, ostiolate. Peridium 75–125 μm diam. (x̄ =96 μm, n=10), outer cells merging with the host epidermal cells, composed of dark brown to black cells dome-shaped, of textura angularis. Paraphyses 3–6 µm diam. (x̄ =4.5 μm, n=10), hyaline, branched, septate. Asci 145–242×8–13 μm (x̄ =187×10 μm, n=20), 8-spored, unitunicate, cylindrical, long pedicellate, apex rounded with a wedge-shaped, J-, apical ring. Ascospores 100–156×2.5–4 μm (x̄ =126×3 μm, n=20), fasciculate, parallel becoming spiral at maturity, fliform, straight or curved, hyaline, aseptate, rounded at the apex, pointed at the base, smooth-walled, without appendages. Asexual morph: Undetermined.


Culture characteristics: Ascospores germinating on PDA within 18 h. Colonies on MEA, reaching 10 cm diam. after 2 months at 25 °C, white at the edge, brown in the centre, outwardly with strong light brown radiations. After 30 days of incubation, colonies smooth, fat, margin entire.


Material examined: THAILAND, Chiang Rai Province, on dead branch of unidentifed plant, 10 January 2016, R.H. Perera, RHP 132 (MFLU 19-0978, holotype), ex-type living culture, MFLUCC 15-1016.


GenBank Accession No: ITS=MN699136, LSU=MN699131.


Notes: Phylogenetic analysis revealed our isolate is closely related to the ex-type of Neoleptosporella clematidis (MFLUCC 17-2074), Chaetosphaeriales genera incertae sedis. It resembles Neoleptosporella in having subglobose to depressed globose ascomata, immersed beneath a small clypeus, asci with wedge-shaped, J- apical ring and, fusiform, fasciculate ascospores (Phukhamsakda et al., in prep.). Neoleptosporella camporesiana can be distinguished from N. clematidis by its longer asci (145–242 μm versus 60–86 μm) and ascospores (100–156 μm versus 32–50 μm) (Phukhamsakda et al. in prep.). A comparison of LSU sequences of N. camporesiana (MFLUCC 15-1016) and N. clematidis (MFLUCC 17-2074) revealed 82 diferent  nucleotides (9.5%). Hence, we identify our fungus as a new lineage of Neoleptosporella (Jeewon and Hyde 2016). ITS data of N. clematidis is not available for the comparison.
