Collybia reinakeana (P.) Henn used to be a wild endemic edible mushroom not until it was discovered in the mountainous area of Puncan, Carranglan, Nueva Ecija, Philippines after the great earthquake that jolted Central Luzon in 1990. It is characterized to having big fruiting bodies (about 1 foot tall) that grow in cluster. Its mycelia were rescued from the wild and the first domestication studies were conducted which lead to the generation of its production technology. It is a nutraceutical mushroom that exhibits antibacterial and anti-hypertensive properties aside from its appreciable content of both standard as well as non- standard amino acids. It also exhibits mycoparasitic habit against species of Aspergillus, Cladosporium and Fusarium. Recently, emergence of this mushroom in the different areas in the Philippines have been reported which prompted our research team to conduct geo – tracking in order to rescue its secondary mycelia in our desire to conserve this endemic species of mushroom. With our conservation efforts, we have tracked the areas where it was found growing and subsequently isolated the secondary mycelia. At present, our research team were able to collect 9 different strains from the different areas namely Bataan (1), Science City of Munoz (2), Urdaneta City (1), San Manuel, Pangasinan (1), Rosales, Pangasinan (1), Bicos, Rizal, Nueva Ecija (1), Dipaculao, Aurora (1) and Bamban, Tarlac(1).
