Brunneoclavispora camporesii Boonmee & Phookamsak, in Hyde et al., Fungal Diversity 100: 61 (2020)

Index Fungorum number: IF557029         Facesoffungi number: FoF06507


Sexual morph: Ascomata 230–380 μm high, 210–290 μm diam. (x̄ = 310 × 252 μm, n = 5), present as dark spots on host surface, immersed, uni-loculate, scattered, subglobose, dark brown, with ostiole. Peridium 23–38.5 μm thick, composed of 4–5 layers of textura angularis, with dark brown cells. Hamathecium 2 μm wide, anatomosed, branched, septate, hyaline, pseudoparaphyses. Asci 109–193 × 21.5–28 μm (x̄ = 140 × 24.5 μm, n = 20), 8-spored, bitunicate, fissitunicate, cylindricclavate to clavate, thickened at the apex, with 2–2.5 μm wide ocular chamber, short pedicellate (ca. 18–29.5 μm long), sometimes expanding up to 59 μm long. Ascospores 21–26.5 × 11–15 μm (x̄ = 25 × 12 μm, n = 20), overlapping 1–2-seriate, muriform, suboblong-ellipsoidal to clavate, transversely 6–7-septate, with longitudinally 1-septate in each cell, brown to dark brown, slightly curved, constricted at the septa, septa thickened, smooth-walled. Asexual morph: Undetermined.


Culture characteristics: Ascospores germinating on MEA within 12 h. Colonies on MEA reaching 9 mm diam. in 7 days at 28 °C, colonies compressed, slightly umbonate, undulate edge, colour of colonies at initially white to yellowish and white at the margin with orange-brown pigmented in medium after 45 days. Mycelium superficial, slightly effuse, radially striate with lobate edge, septate, hyaline, smooth-walled.


Material examined: THAILAND, Chiang Mai Province, Chom Thong, N 18° 31′ E 98° 29′, on decaying wood, 16 November 2010, R. Phookamsak, ITN-03 (MFLU 11-0001, holotype), ex-type living culture, MFLUCC 11-0001.


GenBank Accession No: ITS: MN809329, LSU: MN809328.


Notes: Brunneoclavispora camporesii is morphologically similar to B. bambusae in having brown, muriform ascospores and was collected from a terrestial environment. However, the species can be distinguished from B. bambusae in having subglobose ascomata, cylindric-clavate to clavate, short pedicellate asci and suboblong-ellipsoidal to clavate, transversely 6–7-septate, and longitudinally 1-septate in each cell of the ascospores. Whereas, B. bambusae has elongate conical ascomata with a flattened base, with slit-like openings ostiole. Asci of B. bambusae are clavate, with short to long pedicels and its ascospores are clavate to fusiform, 7–8 transverse septa, with 1–4 longitudinal septa, with a tail-like appendage at the basal cell (Ariyawansa et al. 2015a). Phylogenetic analyses of a combined LSU, SSU and ITS sequence dataset showed that B. camporesii forms a sister lineage with B. bambusae with high support (98% ML, 1.00 BYPP). Therefore, we introduce B. camporesii as a second species in Brunneoclavispora with both species in this genus being saprobes collected from dead and decaying wood in Thailand.
