摘要

神祕湖位於台灣東北部南澳闊葉林保護區內，屬於中海拔略酸性的貧養湖。此湖中滋長豐富的矽藻種類，本文描述在湖積物出現之23種，分屬於5科7屬。其中有7種為台灣的新紀錄種，即Cymbella cuspidata、Cymbella mongolica、Encyonema gracile、Gomphonema augur var. turris、Gomphonema clavatum、Brachysira steindorfiana 和Luticola mutica f. intermedia 等。Brachysira 屬於台灣新記錄屬。本文主要係以掃描電子顯微鏡下觀察到的微細形態構造為依據。

This study described 23 species of diatoms, belonging to five families and seven genera found in the Mystery Lake, a slightly acidic lake, located within a hardwood nature preserve in northeastern Taiwan. Of the species described, seven are new record to Taiwan. They are: Cymbella cuspidata, Cymbella mongolica, Encyonema gracile, Gomphonema augur var. turris, Gomphonema clavatum, Brachysira steindorfiana, Luticola mutica f. intermedia. Brachysira is a new genus to Taiwan. The fine structures of each species are described on the basis of observations under the scanning electron microscope.
