The thin inner coat of certain spores.

A thick-walled spore formed in a bacterial cell. It is very resistant to being killed by heat and various other chemical and physical agents. Endospores are best verified by demonstrating that cultures survive a temperature of 70-80 C for 10 min.

in the Microsporidia, a protective coat of chitin located between the outer protein exospore and the cell membrane.

The type of spore produced during the spherule stage of the life cycle of the fungus Coccidioides immitis, the cause of coccidioidomycosis ("valley fever")

spore produced within the spherule of Coccidioides immitis

resistant, thick-walled asexual spore formed within a bacterial or fungal cell

A type of spore that develops within the cytoplasm of an enveloping mother cell or sporangium.

a small asexual spore that develops inside the cell of some bacteria and algae

a generalized term for a type of spore that is produced within an organism (usually a bacterium)

A spore formed within a spherule by a cleavage process following karyogamy and mitosis.

The innermost layer of a spore wall ( Jackson, 1928). Comment: It is probably homologous with the intine of a pollen grain. Also used as a synonym for the corpus in camerate spores. Mycologists use the term for spores formed on the inside of a sporangium. See also: exospore, perispore. Endosporium ( Erdtman, 1943) Synonym of intine.

1) The inner coat or wall of a spore of certain plants; endosporium; 2) a spore formed within a cell of certain bacteria.

An asexual spore developed within a cell.
