Porina monilisidiata
species of lichen
Porina monilisidiata is a species of corticolous (bark-dwelling), crustose lichen in the family Porinaceae, first described in 2016. This species is characterised by its shiny, olive-green thallus with numerous isidia and low conical ascomata.
Taxonomy
Porina monilisidiata was formally described by the lichenologists Gothamie Weerakoon and André Aptroot in 2016. The type specimen was collected in the Sinharaja Forest Reserve, Sri Lanka, on the bark of a tree on 17 February 2015.
Description
The thallus of Porina monilisidiata is corticate, smooth or slightly rugulose, covering areas up to 10 cm (4 in) in diameter, shiny, continuous, and thin. The colour of the thallus is olive green, surrounded by a thin black prothallus. Isidia are numerous, corticate, the same colour as the thallus, mostly simple, but some are branched, wavy to a bit moniliform, cylindrical, approximately 0.05 mm in diameter and 0.3–0.8 mm high. The algae are trentepohlioid. Ascomata are low conical, approximately 0.7–1.2 mm in diameter, fully covered by a thin layer of thallus through which the dark ascomata appear grey-brown, with a black, 0.1–0.3 mm wide ostiole. Ascospores consistently have nine septa, and measure 65–75 by 10–13 μm.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Porina monilisidiata”, the useful work is to connect “species of lichen” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 19, 2024. The linked authority identifier is Q108282558. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2016 and 2015.
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.
