Abstract: Zhurbenko, M. P. 2021. Studies on lichenicolous fungi in the Uppsala (UPS) collection curated by the late Rolf Santesson. – Herzogia 34: 493 –507. A new genus and species, Stromatoneolamya ugandensis, is described for a lichenicolous ascomycete growing on Canoparmelia nairobiensis that mainly differs from Neolamya peltigerae in its well-developed clypeus, completely immersed ascomata clustered in stromatic warts on the host thallus, and the absence of external periphyses. Three additional new species are described: Lichenopeltella mobergii (on Hypogymnia kiboensis), Llimoniella bryonthae (on Pertusaria bryontha), and Plectocarpon santessonii (on Parmotrema pseudonilgherrense). Polycoccum laursenii is reported as new to the southern hemisphere from Australia, Lettauia hypotrachynae new to Uganda, Merismatium corae new to Guatemala, Scutula miliaris new to China, and Stigmidium triebeliae new to Portugal from Madeira. Lettauia hypotrachynae is first reported from Hypotrachyna densirhizinata and Muellerella lichenicola from Pertusaria papillulata.
