Tricharia duotela
species of fungus
Tricharia duotela is a species of foliicolous (leaf-dwelling) lichen in the family Gomphillaceae. It is characterized by its pale greenish-grey to white color, small ascospores, and preference for open habitats. Found in South Florida, it can be found on the leaves of saw palmetto in pine barrens. This lichen is similar to other species in the genus Tricharia, but it is differentiated by its smaller ascospores and unique diahyphae.
Taxonomy
Tricharia duotela was formally described by lichenologists William Sanders and Robert Lücking. The species was discovered by the first author in Lee County, Florida, at the Florida Gulf Coast University campus on May 31, 2014. The holotype specimen was found on the leaf blade of a Serenoa repens plant. The species epithet duotela comes from the Latin word telum ("weapon"), referring to the morphologically distinct sterile setae and hyphophores of the lichen.
Description
The Tricharia duotela lichen has a thallus that is continuous to dispersed, with areolae measuring 1–3 mm across and 20–30 μm thick. It is pale greenish-grey to white in color and has a cartilaginous, corticiform layer.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Tricharia duotela”, the useful work is to connect “species of fungus” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 14, 2023. The linked authority identifier is Q21308573. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2014.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
