Abstract

Floristic and taxonomic study on the basis of morphological and cytological characteristics of terrestrial algae found in biological crusts of soil from paddy fields of Los Baños, Laguna showed the occurrence of 14 taxa (3 unicellular, 2 colonial, 7 non-heterocytous filamentous and 2 heterocytous filamentous) belonging to the class Cyanophyceae, Chlorophyceae, Klebsormidiophyceae and Trebouxiophyceae. The collection reported in this study represents 9 orders, 10 families, 13 genera and 14 species based on recent combined taxonomical approach. Of these taxa, the occurrence of a rare green alga Chlorolobion braunii (Nägeli) Komárek is reported for the first time in the Philippines. Three species are also reported here based on current taxonomic nomenclature and these are Planktothrix agardhii (Gomont) Anagnostidis & Komárek, Kamptonema chlorinum (Kützing ex Gomont) Struneckỳ, Komárek & J.Smarda and Tetradesmus dimorphus (Turpin) M.J. Wynne. These taxonomic records are considered important information in enriching the knowledge about the diversity and habitat distribution of cyanobacteria and microalgae in the Philippines.
