Thalloidima is a genus of lichen-forming fungi in the family Ramalinaceae.[2] It has 13 species.[3]
Taxonomy
The genus was originally circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852.[4] It was subsumed into genus Toninia by Einar Timdal in 1992.[5] The genus was resurrected for use in 2018 by Kistenich and colleagues following a molecular phylogenetics-led restructuring of the Ramalinaceae.[1]
Description
Thalloidima is defined by the distinctive grey pigment in the [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] rim, which turns violet with K+ and N+ reactions, originally termed as "Thalloidima-grün" (equivalent to [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]). The thallus predominantly appears as flattened [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] to [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. Two species in this genus are not lichenized. While many, if not all species, initiate their lifecycle as parasites on [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], some remain parasitic throughout. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] generally range from ellipsoid to [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] shapes and are 1-septate, though some rare forms are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and 3-septate.[1]
