Fissurina tuckermaniana is a lichen that forms a thin, crust-like growth on bark and belongs to the family Graphidaceae.[1] It is known from subtropical Florida. It has fissure-like, darkened lirellae (slit-like fruiting structures) and unusually large ascospores with three septa, produced in low numbers in each ascus. It also has spinulose (spiny-tipped) paraphyses and periphysoids.
The species was described as new in 2011 by Ralph Common and Robert Lücking. The holotype (the single specimen designated as the name-bearing type; Common 7323D) was collected in April 1997 in Fakahatchee Strand Preserve State Park (Collier County, Florida), along the Scenic Drive (CR 837) near gate 14 in a second-growth area. It is deposited in the herbarium of the Michigan State University Museum (MSC).[2]
The epithet tuckermaniana honors Edward Tuckerman, in recognition of his contributions to North American lichenology. The species resembles Fissurina comparilis and Fissurina comparimuralis in overall appearance, but it can be separated by microscopic features, especially the large 3-septate spores and the spiny structures in the hymenium.[2]
