Malmidea atlanticoides
species of lichen
Malmidea atlanticoides is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Malmideaceae. It is found in Brazil.
Taxonomy
It was formally described as a new species in 2021 by the lichenologists Klaus Kalb and Marcela Cáceres. The type specimen was collected by the authors from the Parque Nacional Serra de Itabaiana (Sergipe) at an elevation of 190 m (620 ft). The species epithet alludes to its resemblance to Malmidea atlantica, the species to which it was initially referred. Subsequent analysis revealed its chemical differences with this species. Malmidea atlanticoides is only known to occur at its type locality.
Description
Malmidea atlanticoides is a crustose lichen with a continuous thallus measuring 75–100 μm in thickness. The thallus surface is verrucose (warty), featuring more or less spherical verrucae that are 0.1–0.25 mm in diameter. The colour of the verrucae ranges from dull ash-grey to greenish-grey and light olive.
The public source identifies “Malmidea atlanticoides” as species of lichen. This brief keeps that definition visible, then builds a research path around Malmidea, atlanticoides and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Malmidea atlanticoides”, 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 Mar 6, 2026. The linked authority identifier is Q123983218. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
