Index Fungorum number: IF833765

Holotype: CBS H-23854, ex-type strain MD1317 .

Detailed description refers to Abdel-Aziz et al. (2020).

Material examined: THAILAND. Nakhon Phanom Province, a small river in That Phanom , on dead submerged decaying wood of unidentified plants, 12 December 2018, Hao Yang, t48 ( MFLU 19-0554 ), living culture KUMCC 19-0214 ; CHINA. Yunnan Province, Qiubei City, a small river in Puzhehei scenic area, on dead submerged decaying wood of unidentified plants, 25 June 2019, Hao Yang, P 39 ( IFRD 500-014 ), living culture KUMCC 20-0154 .

Notes: Pleurotheciella nilotica , introduced by Abdel-Aziz et al. (2020), was collected from decaying submerged wood in River Nile, Sohag City, Egypt. It is characterized by caespitose to loosely fasciculate, brown conidiophores and clavate or lunate, hyaline conidia ( Abdel-Aziz et al. 2020, this study). Our two new collections are identified as Pl. nilotica based on the morphological characters and phylogenetic analyses, as well as nearly identical LSU (identity between KUMCC 20-0154 and ex-type and one nucleotide difference between KUMCC 19-0214 and the ex-type) and SSU (identity between KUMCC 19-0214 and ex-type and one nucleotide difference between KUMCC 20-0154 and the ex-type) sequence data. We provide ITS sequence for this species. Our collections have slightly larger conidia (x = 13.4 × 4.8 μm vs. 10.6 × 2.9 μm) than the type material of Pl. nilotica . This is the first report of Pl. nilotica from Asia ( Thailand and China).

Pleurotheciella aquatica Z.L. Luo, D.J. Bhat, H.Y. Su & K.D. Hyde, Mycol. Prog. 17(5): 517 (2018)

Index Fungorum number: IF821838, Facesoffungi number: FoF 03413

Holotype: MFLU 17-0911 , ex-type strain MFLUCC 17-0464 .

Notes: Pleurotheciella aquatica was introduced by Luo et al. (2018) from a freshwater habitat in Yunnan Province, China. It is characterized by solitary or rarely with two fascicles conidiophores, dark brown at below half, pale brown to hyaline above half and lunate to suballantoid, hyaline, 0–3-septate conidia.
