registering a biome in 1.17 error

[the_lizard_king]

I'm pretty new to modding and I was trying to register a new biome for my mod but I am getting an error that say's

Type mismatch: cannot convert from autumnForest to I

here's my code

 

public class BiomeInit {
	
	public static final DeferredRegister<Biome> BIOMES = DeferredRegister.create(ForgeRegistries.BIOMES, myMod.MOD_ID);
	
	public static final RegistryObject<Biome> AUTUMN_FOREST = BIOMES.register("autumn_forest", () -> new autumnForest());

}

Use the proper naming convention. Also, learn Java.
