Trypetheliopsis boninensis is a species of corticolous (bark-dwelling) crustose lichen in the family Monoblastiaceae.[1] It forms a thin, greenish crust on tree bark and is characterised by small, reddish bumps containing the lichen's spore-producing structures. Originally described in 1937 from the Bonin Islands of Japan, where it was found growing on the Bonin-endemic tree Boninia glabra, the lichen was later recorded from Kyushu in southern Japan. The species served as the type for the genus Trypetheliopsis when Japanese lichenologist Yasuhiko Asahina established it as a new genus of pyrenocarpous lichens.
Japanese lichenologist Yasuhiko Asahina described Trypetheliopsis boninensis in 1937 when he established Trypetheliopsis as a new genus of pyrenocarpous lichens. On the basis of several morphological features, he placed Trypetheliopsis in the family Trypetheliaceae, close to Trypethelium but distinct from it, with T. boninensis as the only species then recognised and therefore the type species of the genus. Asahina based the species on material collected by M. Okabe on the smooth bark of Boninia glabra in the Ogasawara (Bonin) Islands, Japan, on 13 January 1937, and stated that the type specimen was preserved in his own herbarium.[2]
In a 2009 study of pyrenocarpous lichens from Japan, Hiro Kashiwadani and co-authors resurrected Asahina's genus, re-examined his original material of T. boninensis, and broadened Trypetheliopsis to include several species that had been placed in other genera, including the type species of Musaespora, which they treated as a synonym of Trypetheliopsis.[3] Modern catalogues and classifications follow this treatment, listing Trypetheliopsis – and hence T. boninensis – in the family Monoblastiaceae rather than Trypetheliaceae.[4][5]
