Multigene Phylogeny Reveals Haploanthostomella elaeidis gen. et sp. nov. and Familial Replacement of Endocalyx (Xylariales, Sordariomycetes, Ascomycota)

During our investigation of palm fungi in Thailand, two interesting taxa from Elaeis guineensis and Metroxylon sagu (Arecaceae) were collected. Based on phylogenetic analyses of a combined dataset of ITS, LSU, rpb2, and tub2 nucleotide sequences as well as unique morphological characteristics, we introduce the new genus Haploanthostomella within Xylariales, and a new species Endocalyx metroxyli. Additionally, in our study, the genus Endocalyx is transferred to the family Cainiaceae based on its brown conidia and molecular phylogenetic evidence.

Spadicoides palmicola sp.nov. on Licuala sp. from Brunei, and a note on Spadicoides heterocolorata comb.nov.

Spadicoides palmicola sp.nov. is described from a senescent leaf of Licuala sp. collected in Brunei. It differs from other Spadicoides species in having verruculose conidiophores producing verrucose, obclavate, rostrate, multi-euseptate, versicoloured conidia. Spadicoides obclavata Kuthub. & Nawawi var. heterocolorata R.F. Castañeda, Guarro & Cano is considered distinct from Spadicoides obclavata, and Spadicoides heterocolorata comb.nov. is proposed.Key words: Hyphomycetes, Licuala, palm fungi, systematics, tropical fungi.
