LIFE CYCLE OF FUNARIA (Division: Bryophyta, Class: Bryopsida, Order: Funariales, Family: Funariaceae, Genus: Funaria) Occurrence: Funaria is a terrestrial moss which grows as dense green patches, in moist shady conditions such as damp soil, shady banks, damp tree trunks and walls. It is circular, cup-shaped lid, present at the top of the capsule. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. They are hygroscopic in nature. In this article we will discuss about the anatomy of funaria. 9. TOS4. Sexual reproduction is oogamous and takes place by antheridia and archegonia.
