The strings and documentation don't make it too easy to distinguish, but the docs do explicitly distinguish between aDH and ADH. I think "DH" includes any and every cipher that might use DH, but there's a good chance that for a cipher string like TLS_DH_DSS_WITH_AES_256_GCM_SHA384, which uses "DH", it's actually part of the "aDH" umbrella (certificate carries DH keys). (Credit to the original author of the article for spotting that one via RFC5246.)
