Index Fungorum, Faceoffungi, MycoBank, GenBank, Fig 1-3.
Classification: Parabambusicolaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi.
Etymology: Named after Prof. Kevin D. Hyde for his contributions to the fungal diversity of Asia.
Saprobic on the surface of decaying branches. Sexual morph: Undetermined. Asexual morph: hyphomyceteous. Conidiophores reduced to conidiogeneous cells. Conidiogenous cells macronematous, mononematous, erect, ampulliform, wider base, smooth, unbranched or rarely branched. Conidia holoblastic, monoblastic, digitate or irregular, dictyosporous, brown to dark-brown, smooth to slightly roughened, euseptate, base truncate.
Notes: The nucleotide BLAST results of ITS, LSU and tef1-α sequences of our collection (AMH 10455) revealed the closest matches as species in Neomultiseptospora, Neoaquastroma, Monodictys, Parabambusicola and Pseudomonodictys. In the phylogenetic analyses (Fig. 35; Senanayake IC et al. 2023), our collection (AMH 10455) clustered with species in Neoaquastroma with ML/BI = 72/0.88 statistical support. Neoaquastroma is characterized by immersed, globose to subglobose or irregular-shaped ascomata, short papillate ostioles, a thin peridium, clavate asci with short pedicels, and multi-septate, hyaline ascospores with guttules in each cell.
However, the sexual morph of our collection is undetermined and the asexual morph of Neoaquastroma is also not known. Therefore, our collection cannot morphologically be compare with species in Neoaquastroma. The asexual morph of Parabambusicolaceae is phoma-like species and our collection (AMH 10455) is distinct from them. Further, our collection (AMH 10455) has been obtained from decaying litter from Thane, India, while Neoaquastroma species have been collected from dead twigs of Bauhinia variegate (L.) Benth. and Barringtonia acutangula (L.) Gaertn. in Thailand and on dead twigs of unidentified plant in Thailand and Guizhou Province (China). Thus, geographical distribution of these two genera is significant. Therefore, we propose a new anamorphic genus Kevinia for this lineage.
