P. moniliformis is unlike any other species of Pyrenula in New Zealand in that its spores are of Trypethelium -type, long-fusiform with pointed ends, and with 8 locules instead of the usual 4. Until further collections of this plant are made and its exact status can be determined with accuracy it is here left in Pyrenula.
