Polymeridium submuriforme is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae.[1] It occurs in the Philippines. This [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] lichen is characterized by its pinkish-grey thallus, which does not fluoresce under ultraviolet light. P. submuriforme is similar to Polymeridium cinereonigricans but can be distinguished by its much smaller [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. The ascomata measure 0.3–0.6 mm in diameter, with a solitary, spherical [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] that is [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. As the ascomata age, the wall expands up to 0.2 mm sideways. The ostiole is apical, and the hamathecium is inspersed. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] number 6–8 per ascus, iodine-negative, somewhat [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], and measure 18–20 by 6–7.5 μm. These ascospores are not ornamented and are surrounded by a 1–2 μm wide gelatinous sheath. No chemical substances have been detected in this lichen. The type specimen was collected from Leyte on tree bark.[2]
