Psoroglaena spinosa is a species of lichen in the family Verrucariaceae,[1] first described in 2016. It is characterized by its small fruticose (bushy) [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], which is [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], smooth, dull, and bright green, covering small areas and consisting of tiny [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] that branch into somewhat [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] threads.
Taxonomy
Psoroglaena spinosa was formally described by the lichenologists Gothamie Weerakoon and André Aptroot in 2016. The type specimen was collected in the Sinharaja Forest Reserve in Sri Lanka on 15 February 2015.[2]
Description
The thallus of Psoroglaena spinosa is [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], consisting of tiny [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] dissected into branched, somewhat [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] threads that are almost equally wide along their entire length, about 20–25 μm in width. These threads, for the most part, lie in one plane, with some parts emerging in other directions. The branching is dichotomous [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is hyaline (translucent), [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], with dense and high papillae, approximately 1 μm wide and 2 μm high. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], measuring about 4–6 μm in diameter, 2–3-[[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (arranged in rows), but unordered. [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] were not observed to occur in this species.[2]
The chemical composition of Psoroglaena spinosa was not evaluated in the study.[2]
Distribution and habitat
This species is found on trees in wet lowland tropical rainforests and at the time of its publication was known only to occur in Sri Lanka.[2]
