Caloglossa species occurs in freshwater streams around Southest Asia. We report it from 2 different riverine sites in Kerala, India. Tetrasporangiate plants were observed in field collections from the Periyar River and Chalakkudy River. The Chalakkudy isolate did not reproduce in culture but the Periyar isolate developed abundant tetrasporangial sori in culture. Many spores were discharged and most were abortive, but some germinated normally, sporelings forming male gametophytes with numerous spermatangial sori and females with many procarps, viable carposporophytes and some nonfunctional (no carpospores) pseudocystocarps. Some carpospores germinated forming new tetrasporophytes. Molecular evidence (28S rDNA and rbcL) placed the Indian specimens close to C. beccarii and C. fluviatilis. Considering the freshwater habitat and morphology of vegetative thalli (blade shape, rhizoid arrangement, and number of rhizoid filament per cell), the Indian specimens should be assigned to C. beccarii.

Freshwater red algal diversity and the relationship with water conditions in 22 stream segments in the area around Khao Luang National Park, Nakhon Si Thammarat province, southern Thailand, were studied during a period of twelve months (May 2014 to April 2015). Sixteen species of freshwater red algae, belonging to eight genera (Audouinella, Balliopsis, Batrachospermum, Caloglossa, Compsopogon, Kumanoa, Sirodotia, and Thorea) were identified, which were all reported earlier for the country. Thorea clavata (Thoreaceae) was the most common species occurring in eight stream segments. Caloglossa beccarii sensu lato (Delesseriaceae) and Sirodotia huillensis Skuja (Batrachospermaceae) had the highest percent cover with up to 40% and 20% per stream segment, respectively. The water quality showed most sites to be unpolluted or ultra-oligotrophic to oligotrophic. Canonical Correspondence Analysis revealed some trends in occurrence of individual species with stream environmental variables: Batrachospermum sp.with strong current velocity; Kumanoa hirosei with high turbidity, total dissolved solid and alkalinity; Caloglossa beccarii with high conductivity; Kumanoa tabagatenensis with high ammonia-nitrogen and Thorea siamensis with high calcium and magnesium. In view of the scarce studies on the stream ecology of freshwater red algae in Philippines and neighbouring countries, it is expected that the data presented here would be helpful in more critical further studies in south-east Asia in general.

The mangrove algal flora of Guam and the Federated States of Micronesia has been poorly explored. We add to our knowledge of this region by observations of collections from these regions. This paper presents new and additional records of: Rhodophyta-Acrochaetium globosum, Colaconema sp., Caulacanthus indicus, Bostrychia moritziana / B. radicans, B. radicosa, B. simpliciuscula, B. kelanensis and B. tenella, Murrayella periclados, and Caloglossa ogasawaraensis; Chlorophyta-Boodleopsis carolinensis; and Phaeophyceae-Dictyota adnata, Dictyotopsis propagulifera, and Canistrocarpus cervicornis. Most specimens were cultured to investigate their reproductive biology and many specimens were further identified using molecular data. Low molecular weight carbohydrates (dulcitol, sorbitol, and digeneaside) were identified in samples of B. radicosa and B. simpliciuscula. We also present data on manganese-rich deposits found on B. simpliciuscula and B. tenella in culture, possibly formed by epiphytic bacteria.

Objective : The purpose of this dissertation is to make a list of the Ceramiales growing naturally in the Korean coastal waters, and to carry out a survey on the current distribution status to investigate the Ceramiales which can be used as medicinal herbs. Methods : References and research papers about herbology published at home and abroad were examined. Results : The results of this study were as follows: 1. A total of 60 genera and 157 species of Ceramiales was found in the Korean coastal waters among which 5 genera and 6 species(approximately 4%) were medicinal plants. 2. Out of the 157 species of Ceramiales 67 species belonged to Rhodomelaceae, and out of the 6 species of medicinal plants 3 species belonged to Ceramiacera. 3. Among the medicinal parts 6 species belonged to algae. 2 species had flatness property, and 3 species had salty flavors. 4. As for the domestic distribution of medicinal plants, four species are distributed on the coast of the country, and Charmakji Caloglossa leprieuriii is distributed at the mouth of the Nakdonggang River and Goheung, Jeollanam-do. 5. 6 species had the efficacy of Spleen, stomach and large intestine meridian 2 species had the potency of remove phlegm, which helps to remove quench one's phlegm in human body. 6. None of the total medicinal Ceramiales were toxic. Conclusion : There were totaled to 60 genera and 157 species in Theaceae in Korea and among them medicinal plants are 5 genera, 9 species, some 4% in total.

본 조사는 1986년 1월부터 4월까지 경남 하동군 김양식장에서 작황조사, 병해조사, 부착생물조사 등을 통해 작황저조의 원인을 분석하고자 실시되었다. 그 결과 본 조사지역의 경우 김의 단위당 생산량은 섶발이 평균 31.53g/피, 그물발이 평균 6.020g/10cm이었으au 대조구의 경우는 섶발이 평균 46.31 g/피, 그물발이 평균 6.225g/m로, 섶발의 경우 대조구가 높았으나 그물발의 경우는 큰 차이가 없었다. 김 부착층은 김의 단위당 생산령과 매우 밀접한 관계를 보였다. 즉 섶발의 경우 50cm 이하인 수식부탁 범위를 가지는 조사정점 전부가 생산량이 20g/피 이하인 정점과 일치하고 있으며 이들 조사 정점의 대부분이 등이 높은 섶 양식장의 서편 증 광양제철소 맞은 편에 위치하고 있다. 유아개체수는 지점별로 다소 차이는 있으나 본 조사정점의 전체 평균치는 961 개체로 대조구의 966개체와 별로 차이가 없었다. 병해조사 결과 병해의 대부분은 구멍갯병과 쪼그랑 병이었으며 양식말기에 가서는 병세가 다소 호전되는 경향을 보였다. 섶발 양식장의 주된 부착생물은 고랑따개비(Balanus albicostatus), 가시파래(Enteromorpha prolifera), 매생이(Capsosiphon fulvescens), 고리매(Scytosiphon lomentaria)였으며 낙동강 하구에 서식하는 것으로 알려진 홍조류의 일종인 Caloglossa leprieurii가 분포하였다. 따라서 1986년도산 하동 김의 작황감소의 주된 원인으로 수직부착범위의 감소, 병해, 해황의 변화, 부착생물, 김발의 정리와 관리문제를 들 수 있었다.
