Pleurocapsales
order of Cyanobacteria

The Pleurocapsales are an order of coccooid cyanobacteria. Pleurocapsales are characterized by having boocytes, specialized cells where multiple fission takes place.
Their ecology is mainly endolytic and calcareous, they are found inside rocks and in low light conditions. Pleurocapsales were thought to be related to Chroococcidiopsis but recent work with phylogenetics of the 16S rDNA gene has shown that Chroococcidiopsis belongs to its own order Chroococcidiopsidales.
Some genera within Pleurocapsales form pseudo-ramifications such as Pleurocapsa sp., Odorella sp, and all the genera within the Hyellaceae family.
Historically, the order Pleurocapsales has been one of the least studied orders of cyanobacteria, due to its endolithic ecology making them difficult to observe.
Most recently, the order Pleurocapsales has been subsumed within the order Chroococcales.
Begin with the source’s own compact description: “Pleurocapsales” is order of Cyanobacteria. The dossier treats that line as a proposition to test through Pleurocapsales, order and Cyanobacteria, not as a finished interpretation.
Why this record matters
The phrase “order of Cyanobacteria” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 26, 2025. The linked authority identifier is Q12045595. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
