Agonimia tenuiloba is a species of corticolous (bark-dwelling) lichen in the family Verrucariaceae. Found in Brazil, it was formally described as a new species in 2013 by lichenologists André Aptroot and Marcela Cáceres. The type specimen was collected by the authors in the Estação Ecológica de Cuniã [es] (Rondônia), where it was found growing on smooth tree bark in a rainforest. The lichen thallus comprises tiny, green, fan-shaped (flabellate) lobes (about 0.1 mm wide) and spherical goniocysts (clumps of photobiont cells surrounded by fungal hyphae).[1] Its ascomata are in the form of perithecia that are 0.3–0.4 mm wide and grey in colour due to a thin thalline cover. Its ascospores typically measure 30–50 by 20–35 μm.[2] The European species Agonimia flabelliformis is similar in morphology, but it has shorter and narrower ascospores.[1]
