Pronectria oligospora: red dots on Punctelia subrudecta Pronectria oligospora was recorded at 30 sites in The Netherlands during the past two years. Consequently, it can be considered a very common lichenicolous fungus. Pronectria oligospora is distinguished from other lichenicolous fungi for its perithecia, which are immersed and lack setae. Furthermore, at least in The Netherlands Pronectria oligospora seems to be largely confined to the host Punctelia subrudecta.
