Gymnocarpium

See list of 2 species in this genus

Hybrids in this genus, which are likely underreported, often possess two types of spores—smaller, black, malformed spores and larger, brown, round spores. Hybrids are not confined 
to areas of parental sympatry. References: Pryer (1993), Pryer and Haufler (1993).
