Allopyrenis tenuis is a species of squamulose lichen-forming fungus in the family Phylliscaceae.[1] It was first described as a new species in 1963 by Aino Henssen, as Phylliscum tenue. The type of Phylliscum tenue was collected by Henssen in Humboldt County, California, at about 1,000 m (3,280 ft) elevation. The specimen was gathered from seepage-streaked exposed volcanic rock.[2] Matthias Schultz and María Prieto recombined the taxon into the new genus Allopyrenis in 2024, following a molecular phylogenetics-informed reorganization of the class Lichinomycetes.[3]
It has dark reddish-brown, roughly rounded [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] measuring about 0.5–0.75 mm across. The thallus surface is [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] because it is covered with clusters of lichenized cyanobacterial cells, about 20–50 μm wide; it lacks both lobules and surface [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. Its fruiting bodies (apothecia) are small, about 200–250 μm wide, and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], with a prominent [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] but no [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. The asci are club-shaped with rounded tips. In young apothecia, only a few primary paraphyses are present, and the [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] or only slightly opened.[4]
Initially described from specimens collected in California,[2] and later found in Alaska,[5] it has also been recorded from Venezuela.[4]
