Thus it may clear that; the organism or structure which resemble to the thallus is called thalloid. Sometimes it is also called as thallodal/ thalliform/ thalline or thallose.

Exceptionally some vascular plants like Lemnoideae showing thallus like structures are sometimes referred as thalloid.

The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where the structure of a vascular plant is in fact thallus-like, it is referred to as having a thalloid structure, or sometimes as a thalloid...
