Yes, fungi can survive in space and may even thrive there.
Based on observations from the Mir Space Station, fungi have demonstrated the ability to not only survive but also spread in the harsh conditions of space. The fact that a fungus was able to proliferate within the enclosed environment of a space station suggests a resilience and adaptability that could allow them to endure and potentially flourish in the vacuum and radiation of outer space. This does not guarantee they would automatically thrive, but it indicates a strong potential for survival.
