Genus-species names
These should be typed in italics except Author(s) name, e.g. Cladophora albida (Hudson) Kützing. Spell out the full generic and specific names on the first use: Enteromorpha linza. Thereafter, the genus name may be abbreviated to the first letter: E. Linza. If the name appears frequently and may be sonfused with another genus whose first letter is the same, spell both names out every times. Never abbreviate generic names when used alone; also, do not abbreviate the species name when a subspecies is designated. For example: B. thuringiensis israelensis, not B. t. israelensis
