1905 J. C. Arthur in Bot. Gaz. 39 221 For the sorus of the first spore-stage, usually..called aecidium, [etc.]..I propose aecium..derivatives aecial, aeciospore, etc.
1928 C. E. Owens Princ. Plant Pathol. xix. 394 The aeciospores are functional, being the means by which the rust organism is transmitted from the barberry bush back to the wheat or other grass host.
1962 Salina (Kansas) Jrnl. 24 Apr. b6/2 The spore..which attacks wheat is the aeciospore. The aeciospore is the actual start of the red and black rust stages.
2005 Adv. in Agronomy 86 202 The effect of temperature on latent period and aeciospore production..was determined.
