The position and size of the spore are of considerable use in differential diagnosis.
Budding occurs in some kinds of yeast, and would be classified by some authorities under spore formation, but in practice it is so obviously a "budding" that it may be so classified.
The pellicle which forms on the surface affords an ideal place for spore formation.
Budding, division, and spore formation are the three chief ways in which Schizomycetes and Saccharomycetes (yeasts) reproduce their kind.
At its maturity, and before its rupture of the bacillary capsule, a spore is observed to be bright and shining, oval and regular in shape, with concentrated contents, and frequently causing a local expansion of the bacillus.
Spore formation may result in the production of germinating cells inside the capsule of the bacillus, endospores, or of modified individuals, arthrospores.
The spore now escapes and commences its individual existence.
The terminal spore of Bacillus tetani is well known.
For it happens that different species show slight differences in spore formation, e.
When the spore is ripe or has exhausted the parent bacillus, it may take on a resting stage, or under favourable circumstances commence germination, very much after the manner of a seed.
The tough capsule gives way at one point, generally at one of the poles, and the spore sprouts like a seed.
It is important to note that spore formation in bacteria must not be considered as a method of multiplication.
In the Dictyoteae the frond is mostly flat, with a reticulated surface, which is sprinkled when in fruit with groups of naked spores or spore cysts.

Spore formers such as anthrax can survive for an extended time, even under very adverse environmental conditions (dry, extremes of temperatures, and flooding).
Bursting through the skin of the plant may be seen a dense forest of threads, each thread bearing a spore with a joint across the middle.
When a spore in due course germinates, its protoplasmic contents escape through a small aperture in its wall and begin moving about of their own accord in a slow writhing manner.
At C some of the threads and spores are still further enlarged to two hundred diameters, and at D one ripe spore is shown falling from the thread and breaking asunder--each piece is a reproductive body or spore.

In the plants of the genus Morchella the spore sacks, with one or two exceptions, contain eight spores.
A characteristic of this species which distinguishes it from others of the same genus is found in the number of its sporidia, spores as seen in the ascus or spore sack.
A spore is a minute cell containing a nucleus or living germ, the reproductive cell germ called by some authors the germinating granule.
The spore is the reproductive organ of the mushroom.
It will be observed that in color down to color of the spore by transmitted light, the three species are exactly the same; constitute a suite, so to say.
Whether a species brought from spore to maturity on artificial diet would conform in any reasonable way to our dim concept of its identity is also, it would seem, a problem.
Sporangia none; spores superficial, borne on erect papillae or pillars, or even on the inside of minute depressions or pits; each spore surmounting a delicate pedicel or stalk.
The sporangia are at first black; after spore disposal pale ferruginous.
It has the characteristic spore and capillitium but in form and habit differs very decidedly.
The wall of thespore is ruptured and the protoplasmic content escapes as a zoospore indistinguishable so far from an amoeba, or from the zoospore of our chytridiaceous fungi.
The spore cases have a wall with a shiny brown covering, or apparently with this covering worn off and exhibiting an interior white shell.
All these plants begin with a spore or minute colourless cell of living matter (s, Fig.
A spore from a former plant has fallen perhaps on the window-pane, or some other spot over which the fly has crawled, and being sticky has fixed itself under the fly's body.
Antheridia or archegonia, or both, formed upon the stem or branches of the plant itself, which is developed from the germinating spore usually with the intervention of a filiform or conferva-like prothallus.
To the base of each spore are attached 4 thread-like and club-shaped elastic filaments, which roll up closely around the spore when moist, and uncoil when dry.
It should also be observed that an increase in heat above this temperature did not materially diminish the number of organisms present, indicating that those forms remaining were in a spore or resistant condition.
It is these spore forms that make it so difficult to thoroughly sterilize milk.
It is certain that all pathogenic microoerganisms, except the very few sporeformers in that stage, are killed by proper pasteurization.
Gradually the remnants of the former cell contents and the old cell wall disappear or dissolve and the sporebecomes "free" (Fig.
In one or two instances the entire spore swells up, lengthens and becomes a rod without any special germination unless this type might be designated bi-polar.
Some bacteria are readily killed and others, even non-spore formers, are only slightly affected.
Further, though many pathogenic bacteria are killed by drying, many more, including the spore formers, are not.
In the original slide the spore was stained red and the developing bacterium blue.
The point at which the spore capsule bursts to permit the new cell to emerge is characteristic for each kind of bacterium.
Sometimes the spore develops in the end of the cell either without (Fig.
This thickened cell wall is called the "spore capsule.
If the diameter through the cell is increased, then the cell with the contained spore becomes spindle-shaped.
From the above description it follows that the spore is to be considered as a condensation of the bacterial protoplasm surrounded by an especially thick cell wall.
The spore in the center of the field shows a rod growing out of it laterally.
Later, when conditions become favorable for its germination, the spore may form a new filament of pond scum.
This spore is usually protected by a wall and may withstand very unfavorable conditions of dryness or heat; even boiling for several minutes will not kill some forms.
The rapid process of sporeformation results in the breaking down of the blood corpuscles and the release of the spores, and the poisons they manufacture, into the blood.
All of these collectively are called spore plants.
This fungus begins its life as a sporein some part of the tree which has become diseased or broken.
These contain numerous very small spore sacs (E), each with eight spores.
The young spore thus formed contracts somewhat, becoming oval in form, and soon secretes a thick wall, colorless at first, but afterwards becoming brown and more or less opaque.
The outer, dry, brown coat of thespore is first ruptured, and often completely thrown off by the swelling of the spore contents.
The nucleus subsequently divides repeatedly, until there are eight nuclei, about which the protoplasm collects to form as many oval masses, each of which develops a wall and becomes a spore (Figs.
As the spore fruit ripens, it opens at the top, and spreads out so as to expose the spore sacs as they discharge their contents (Fig.
In these the sporesacs are borne directly upon the filaments without any protective covering.
They fasten themselves at intervals to the substratum, and send up from these points clusters of short filaments, each one tipped with a spore case, or "sporangium.
If the young spore fruit is treated with chlor-iodide of zinc, it is rendered quite transparent, and the young spore sacs colored a beautiful blue, so that they are readily distinguishable.
As thespore ripens, it loses its green color, becoming colorless, with a few reddish brown specks scattered through it (F).

These are hygrometric: when moist they are rolled up over the spore; when dry they straighten, and exhibit lively movements, closing over the spore when breathed upon, and unrolling promptly a moment after as they dry.
The spore swells and elongates and the contents grow forth to a cell like that which produced it, in some cases clearly breaking through the membrane, the remains of which may be seen attached to the young germinal rodlet (figs.
