Nanostictis is a genus of lichenicolous (lichen-dwelling) fungi in the family Stictidaceae. These tiny fungi produce minute fruiting bodies that remain embedded within their host lichens and are characterised by very slender, thread-like ascospores divided by multiple cross-walls. The genus contains nine species that parasitise various lichen hosts, though its relationship to similar genera remains uncertain due to the lack of molecular studies on any Nanostictis species.
