Anamorph: not known.
Teleomorph: ascomata perithecia, in clusters of 5 to 15 within galls of the host lichen; galls 0.6-0.9 (-1.2) mm diam., pulvinate, slghtly darker and browner than the surrounding thallus, the perithecia visible as distinct bulges in the gall surface with broad ± flat black necks that hardly extend beyond the substratum surface. Ascomata 160-195 µm diam. and 220-260 µm tall, pyriform, without a distinct clypeus, the ostiole not papillate. Peridium 12-15 µm thick in the basal region, composed of 5-7 layers of strongly flattened thin-walled irregularly angular cells to 10 µm diam., almost completely occluded by melanized material except at the base; massively thickened (to ca 50 µm) around the ostiole which is surrounded by hardly protruding strongly melanized hyphae to 20 µm long and 2.5 µm diam. Interascal tissue composed of very thin-walled arching paraphyses to 2.5 µm diam. Asci 87-95 x 7-8 µm, narrowly cylindric-fusiform, short-stalked, the apex obtuse, thin-walled and not fissitunicate, without visible apical structures, not blueing in iodine, 4-spored. Ascospores 58-64 x 2.5-3 µm, filiform, falcate, gradually tapering towards the acute apices, not constricted at the single ± median septum, thin-walled, smooth, without an epispore, gelatinous sheath or appendages.
Not evaluated; only a single collection is known.
Easily distinguished from other Neolamya species by the four-spored asci and host preference. There are a few species of Lichenochora that have been described with elongate ascospores (e.g. L. bacidiispora Etayo (2017) on Parmotrema sp. from Ecuador) and the gall-forming nature of the species from Parmeliella and the four-spored asci make a placement there possible. The relationships of Neolamya and Lichenochora merit examination. Sagediopsis species also have elongate, falcate ascospores but the hymenium blues in iodine in this genus.
Causing galls on the thallus of Parmeliella parvula.
Known from a single collection in a strongly oceanic part of VC97 W Inverness.
