endospore

 [en´do-spor]
1. a thick-walled body formed within the vegetative cells of certain bacteria (e.g., Bacillus, Clostridium, Sarcina) that can withstand adverse environmental conditions for prolonged periods; under favorable conditions it will germinate to form a vegetative bacterium.
2. an asexual fungal spore produced within the hyphae or cell, as in a spherule of Coccidioides immitis or in a sporangium.

en·do·spore

(en'dō-spōr),
1. A resistant body formed within the vegetative cells of some bacteria, particularly those belonging to the genera Bacillus and Clostridium.
2. A fungus spore borne within a cell or within the tubular end of a sporophore as in the spherule of Coccidioides immitis.
[endo- + G. sporos, seed]

endospore

(ĕn′də-spôr′)
n.
1. The inner layer of the wall of a spore.
2. An asexual spore developed within a cell, as that formed by some bacteria.
