The life cycle of wheat rust, Puccinia graminis

teliospore: thick-walled resting spore produced by some fungi, notably rust and smut fungi, from which the basidium is produced (Puccinia teliospores)

pycniospore (syn. spermatium): haploid, sexually derived spore formed in a pycnium of rust fungi (SEM of pycnium containing pycniospores)

uredinium (also uredium; pl. uredinia): fruiting body (sorus) of rust fungi that produces urediniospores (left: uredinia of Puccinia graminia f. sp. tritici; right: SEM of single uredinium of Puccinia recondita)

urediniospore (also urediospore, uredospore)  : the asexual, dikaryotic, often rusty-colored spore of a rust fungus, produced in a structure called a uredinium; the "repeating stage" of a heteroecious rust fungus, i.e. capable of infecting the host plant on which it is produced (Puccinia graminis)
