'autosporic' originates from Modern/New Latin and Greek elements: Greek 'auto-' meaning 'self' and Greek 'spora' meaning 'seed' or 'spore', combined with the adjectival English suffix '-ic'.

'autosporic' developed in scientific English by derivation from 'autospore' (a Modern Latin/New Latin or coinage from Greek elements 'autospora' / 'autospore'), with the suffix '-ic' added in late 19th to early 20th century botanical usage to form the adjective.

Initially it simply indicated a relation to an 'autospore'; over time it came to be used more specifically to describe organisms or processes that produce autospores or exhibit autosporogenesis.
