Pyrenula moniliformis

The species is corticolous, has a crustose thallus, no pseudocyphellae, and is cream to pale brown in colour. It can be distinguished from other members of Pyrenula due to having apiculate spores which are 5- to 7-septate, which range in size between by and by . == Taxonomy ==

The species was first described in 1860 by Charles Knight, using the name Verrucaria moniliformis. It was moved to the genus Pyrenula in 1894 by Johannes Müller Argoviensis. The species was only known from its type collection until 2025, when new specimens were discovered in the Unitec Institute of Technology herbarium, including student specimen collections dating back to 2015. After rediscovery, the species was redescribed in 2025 by Andrew J. Marshall, Peter de Lange, Dan Blanchon and André Aptroot, based on fresh specimens. The holotype is held by the British Museum, and while Knight did not specify a location, is presumed to have been collected from the Auckland Region. == Ecology ==

The species tends to grows in shaded early-stage successional forest dominated by māhoe trees either as a canopy or subcanopy. == Distribution and habitat ==

The species is endemic to New Zealand, living exclusively on the bark of māhoe trees. ==References==
