From the Vault: Realms

Murmuring Bosk is a Forest, but it isn't a basic land. Things that affect basic lands don't affect it. Things that affect basic land types do. For example, you can't find Murmuring Bosk with Fertilid's ability ("searches their library for a basic land card"), but you can find Murmuring Bosk with Everbark Shaman's ability ("search your library for two Forest cards").
