Abstract
The genus Peniophora is known to be distributed from boreal to tropical regions worldwide. During surveys of plant diseases in southern Thailand in 2022 and 2023, two specimens of rotten snake fruits (Salacca zalacca) were collected. The new species, P. salaccae, is described based on collections with morphological and molecular data. This species is characterized by orange-gray to brownish-orange basidiomes, simple-septate generative hyphae, brown lamprocystidia, subclavate to subcylindrical gloeocystidia, and subtriangular basidiospores. It can be distinguished from P. trigonosperma by its larger basidiospores and shorter lamprocystidia. Molecular phylogenetic analyses of the internal transcribed spacers (ITS) and the large subunit (nrLSU) of the nuclear ribosomal DNA (rDNA) confirmed the position of the new species within the genus Peniophora. The full description, color photographs, illustrations, and the phylogenetic tree showing the position of P. salaccae are provided. Additionally, pathogenicity tests showed that P. salaccae could infect snake fruits, which developed the same symptoms under artificial inoculation conditions as those observed in the field.
期刊介绍:
Phytotaxa is a peer-reviewed, international journal for rapid publication of high quality papers on any aspect of systematic and taxonomic botany, with a preference for large taxonomic works such as monographs, floras, revisions and evolutionary studies and descriptions of new taxa. Phytotaxa covers all groups covered by the International Code of Nomenclature foralgae, fungi, and plants ICNafp (fungi, lichens, algae, diatoms, mosses, liverworts, hornworts, and vascular plants), both living and fossil. Phytotaxa was founded in 2009 as botanical sister journal to Zootaxa. It has a large editorial board, who are running this journal on a voluntary basis, and it is published by Magnolia Press (Auckland , New Zealand). It is also indexed by SCIE, JCR and Biosis.
All types of taxonomic, floristic and phytogeographic papers are considered, including theoretical papers and methodology, systematics and phylogeny, monographs, revisions and reviews, catalogues, biographies and bibliographies, history of botanical explorations, identification guides, floras, analyses of characters, phylogenetic studies and phytogeography, descriptions of taxa, typification and nomenclatural papers. Monographs and other long manuscripts (of 60 printed pages or more) can be published as books, which will receive an ISBN number as well as being part of the Phytotaxa series.
