Pyrenula dalmatioides is a species of lichen in the family Pyrenulaceae which is endemic to New Zealand. It was first described in 2025 by Andrew J. Marshall, Dan Blanchon, Peter de Lange, and André Aptroot. Found in the northern North Island, the species lives almost exclusively in mangrove forests, and is an early coloniser species, displaced by different lichens over time.
The species is corticolous, has a crustose thallus, no pseudocyphellae, and is white to creamy-white in colour. It can be distinguished from other members of Pyrenula due to having 5- to 7-septate apiculate spores, which measure between 22 μm (0.00087 in) by 8 μm (0.00031 in) and 30 μm (0.0012 in) by 10 μm (0.00039 in).[1]
Taxonomy
The species was first described by Andrew J. Marshall, Dan Blanchon, Peter de Lange, and André Aptroot in 2025.[1] The species epithet was chosen due to the thallus of the lichen resembling a Dalmatian dog's coat.[2] The holotype is held by the Unitec Institute of Technology herbarium.[3]
