mytheme

has 'content'. It contains both signification and meaning.

Unlike Levi-Strausss mythemes (the 'gross constitutive elements' of myth, by analogy with phon-eme), phonemes are bits of meaningless and non-significant information. Phonemes and phonemic oppositions are the tools of analysis and articulation (whose basic characteristic is difference) in a system in which both signification and meaning are outside the phonemic structure. Mythemes and oppositions between mythemes, on the contrary, involve both signification and meaning: they have content. (Wilden 1972a .pdf)

is the smallest unit (much like how a phoneme is the smallest unit of speech that distinguishes one unit from another) in myths.

Myth differs from language (as Saussure describes it) because the basic units of myth are not phonemes (the smallest unit of speech that distinguishes one utterance from another, like a letter), morphemes (the smallest unit of relatively stable meaning that can't be subdivided, like a non-compound word), or sememes (the meaning expressed by a morpheme), or even signifiers and signifieds, but rather are what Levi-Strauss calls 'mythemes.' ' (net),

is the smallest unit of meaning in myth, unique in that, in contrast to phonemes which are bits of meaningless information lacking signification, mythemes involve both meaning and signification.
