Biology:Eschatogonia
Eschatogonia is a genus of lichen-forming fungi in the family Ramalinaceae.[1] It has seven species.[2] The genus was circumscribed by the Italian lichenologist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1853.[3]
Description
The genus Eschatogonia includes lichens with a [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] thallus, meaning the body of the lichen is composed of small, scale-like lobes known as [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. These squamules have a single layer of cortical (outer) tissue on both their upper and lower surfaces. The lichen's [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], or photosynthetic partner, is a green alga.[4]
The apothecia (fruiting bodies) are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (directly attached to the surface without a stalk) and lack a [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], meaning they do not have a rim of thallus-derived tissue around them. The apothecia range in colour from flesh-toned (carneous) to reddish brown. Each ascus (spore-producing sac) within the apothecia typically contains eight spores. These spores are colourless and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], meaning they are spindle-shaped, tapering at both ends.[4]
