Apoglossum minimum and A. gregarium (Delesseriaceae, Rhodophyta),Two New Records from Korea

Abstract

Two species of Apoglossum is newly recorded in Korea collected from subtidal habitats of Jeju Island. Apoglossum minimum Yamada has previously been known only from the coast of Japan. It is characterized by having corticated midrib but lacking microscopic veins. Apoglossum gregarium (Dawson) Wynne is reported for the first time from the north western coast of Pacific Ocean. It has been distinguished by its ecorticate midrib from the former species. Their morphological characteristics in detail and taxonomic issues are discussed.

“…It did not show mixed-phase phenomena such as the occurrence of spermatangia and tetrasporangia on the same blade as reported by Park et al (2006) in Korean material.…”

“…Despite the small stature of this algal species (less than 10 mm in height) and its usual deep sublittoral habitat, Apoglossum gregarium has been reported to occur from scattered tropical, subtropical, and warm temperate locations, including southern California (Stewart 1974(Stewart , 1989, Puerto Rico (Ballantine & Wynne 1985), Kwazulu-Natal, South Africa (Wynne & Norris 1991), Italy (Sartoni & Boddi 1993), the Mediterranean coast of Spain (Clavell & Polo 1998, 2000, Hawaii (Abbott 1999), Bermuda (Schneider 2000), the State of São Paulo, Brazil (Horta & Oliveira 2001), Korea (Park et al 2006), Greece (Tsiamis & Bellou 2010), Venezuela (Gómez et al 2013), and the northern Gulf of California, Mexico (Norris 2014). It is an easily recognized species because the usually simple blades often arise from a shared prostrate stolon and have a ruffled, undulate appearance, and they have a conspicuous uncorticated midline.…”
