Acanthocladium japonicum Broth. et Par. K(n)=5=V(H)+2V+J+J(h)
Acanthocladium nakanishikii Broth. K(n)=9=V(H)+4V+3J+J(h)
Acroporium nipponense Sak. K(n)=8=V(H)+4V+2J+J(h)
Ctenidium capillifolium (Mitt.) Broth. K(n)=11=V(H)+5V+4J+J(h)
Drepanocladus uncinatus (Hedw.) Warnst. K(n)=11=2V(H)+5V+3J+J(h)
Bryhnia tokubuchii Broth. K(n)=10=V(H)+6V+2J+J(h)
