Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. E. Henn. life Cycle

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

spermagonium) : globose or flask-shaped haploid fruiting body of rust fungi bearing receptive hyphae and pycniospores (SEM)

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

Telia on wheat plants and Teliospores of Puccinia graminis f. Note dark color and thick cell walls.

pustule: small blisterlike elevation of epidermis formed as spores emerge (pustules of wheat stem rust urediniospores)

rust: a disease caused by a specialized group of Basidiomycetes that often produces spores of a rusty color (stem rust of wheat)

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)

promycelium (pl. promycelia): in rust and smut fungi, a germ tube issuing from the teliospore and bearing the basidiospores (germinating teliospore of Puccinia pampeana
