Fissurina varieseptata is a species of crustose lichen in the family Graphidaceae.[1] It is known from Florida. It has small, fissure-like lirellae (slit-like fruiting structures) and ascospores that usually have 5–7 transverse septa (internal walls), rather than the more typical three in closely similar species.
Fissurina varieseptata was described as a new species in 2011 by Ralph Common and Robert Lücking. The holotype (the single specimen designated as the name-bearing type; Common 7413A) was collected in April 1997 in Fakahatchee Strand Preserve State Park (Collier County, Florida), at Big Cypress Bend in an old-growth cypress swamp. It is deposited in the herbarium of the Michigan State University Museum (MSC).[2]
The specific epithet refers to the variable number of transverse septa in the ascospores. The species is superficially similar to Fissurina illiterata and may be closely related, but it can be separated by its much more strongly septate spores, a feature unusual in the genus.[2]
