Aphanothece sacra (Suringar) Okada

Japanese: スイゼンジノリ(水前寺苔) - スイゼンジノリ(英語表記)Aphanothece sacra (Suringar) Okada
Aphanothece sacra (Suringar) Okada
A type of colonial cyanobacteria that is a few centimeters long, slightly flattened, and irregular in shape. It grows in springs and the bottoms of ponds and streams in Kumamoto and Fukuoka prefectures in the Kyushu region. The product is sold commercially under the names Suizenji moss and Jusen moss, and is edible. The colonies are a somewhat hard agar-like substance, and when crushed and viewed under a microscope, they are found to contain numerous elliptical, dark green cells measuring 3.5-4.0 μm x 6-7 μm. This alga was first given the scientific name Phylloderma sacrum Suringar as a new genus and species by WFR Suringar (1872-74), but the name was later changed to the above in 1953, as there was no reason to make it a separate genus from Aphanothece .

長さ数cmのやや扁平で不規則な形状をした群体性のラン藻の1種。九州地方の熊本県や福岡県の湧泉およびその近くの池や小川の底に生育する。製品は水前寺苔や寿泉苔(じゆせんたい)などの商品名で市販され,食用に供される。群体はやや固い寒天質で,押しつぶして顕微鏡でみると,内部に大きさ3.5~4.0μm×6~7μmの楕円形,暗緑色の多数の細胞が埋在する状態がわかる。この藻は初めスリンハーW.F.R.Suringarにより新属新種としてPhylloderma sacrum Suringarの学名が与えられた(1872‐74)が,後にAphanotheceと別属にする理由がないとして1953年に上記のように学名が変わった。
