Species S. latifrons
Scientific name: Sticta latifrons
Synonym: Lobaria latifrons
Sticta latifrons is a large foliose lichen found in New Zealand, Australia and Papua New Guinea. This lichen is indicative of rain forests and can survive in deep shade. It is attached to the substrata by a basal stalk. Its thallus has a green upper surface of phycobiont (algae) and a dirty white underside. It has pores on the lower (and sometimes upper) surface have a ring or rim around the pore. These pores are called cyphellae (a cuplike pit or depression that is located on the under surface of the thallus.
A lichens that looks similar to Sticta latifrons is the lichen genus Pseudocyphellaria. They differ in that pores are just fuzzy holes ('false' cyphellae).
