ABSTRACT

Lignicolous marine fungi are a particular group of microorganisms that are typically found in mangroves, salt marshes, and estuaries, normally associated with driftwood or submerged wood. During investigations of lignicolous fungi occurring in the estuary Ria de Aveiro, Portugal, wood baits were submerged in a marina for 1 year. Seventeen distinct marine fungal species were identified, with the most abundant taxa belonging to the family Lulworthiaceae. Through single- and multilocus phylogenies based on sequences of the internal transcribed spacer (ITS) region and large subunit (28S) and small subunit (18S) of the ribosomal RNA gene cluster in combination with morphological and physiological data, we describe Remispora submersa, sp. nov., and Zalerion pseudomaritima, sp. nov., as novel species. Additionally, we propose that Papulaspora halima, a species whose taxonomic placement has been somehow confusing, be transferred to the genus Paralulworthia as Paralulworthia halima.

摘要

木质海洋真菌是一类特殊的微生物，通常在红树林、盐沼和河口中发现，通常与浮木或沉水木有关。在对发生在葡萄牙 Ria de Aveiro 河口的木质真菌进行调查期间，将木饵浸入码头中 1 年。鉴定了 17 种不同的海洋真菌物种，其中最丰富的分类群属于 Lulworthiaceae。通过基于内部转录间隔区 (ITS) 区域和核糖体 RNA 基因簇的大亚基 (28S) 和小亚基 (18S) 序列的单位点和多位点系统发育，结合形态学和生理学数据，我们描述了Remispora submersa , sp . 11 月和Zalerion pseudomaritima，sp。nov.，作为新物种。此外，我们建议Papulaspora哈利玛，一个物种，其分类地位一直有点难以理解，转移属Paralulworthia为Paralulworthia哈利玛。
