Sticta arachnofuliginosa

Sticta arachnofuliginosa is a species of foliose lichen in the family Peltigeraceae. Found in Central America and South America, it was formally described by Bibiana Moncada and Robert Lücking in 2012. The type specimen was collected near the Laguna de Chisacá (Cundinamarca Department, Colombia) at an altitude of 3734 m. The lichen, which usually grows on bark but has also been recorded growing on soil, tends to associates with liverworts from the genera Metzgeria, Lepicolea, Plagiochila, as well as the lichen Heterodermia circinalis. It has been recorded from páramo, and temperate forests at elevations ranging from 2300 and 4050 m. The specific epithet alludes to its resemblance to Sticta fuliginosa.
