Phasmaviridae is a family of viruses with negative stranded RNA genomes associated with insect hosts. They are a member of the order Bunyavirales.[1] Phasmaviruses were first discovered in phantom midges of the genus Chaoborus in 2014.[2]
Taxonomy[edit]
The family contains the following six genera:[1]
Ferak feravirus[edit]
Ferak feravirus, a member of the genus Feravirus, has been isolated in cell culture. The virion is enveloped and spherical with a diameter of 80–120 nanometers. The genome has three segments L (6.8 kilobases), M (4.2 kilobases) and S (1.5 kilobases). It encodes five proteins—the polymerase on the L segment, the p12G and the Gc-Gn protein on the M segment and the N and p12 proteins in the S segment.[3]
A Gn–Gc glycoprotein dimer binds to the cell receptor. The virus is endocytosed and escapes into the cytoplasm where it replicates. It is released from the cell by budding.[3]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
