Lamproderma is distinguished by the shining metallic tints of the sporangial wall, and by the short columella scarcely reaching half the height of the sporangium.
Distinguished by the pale silvery sporangial wall and the clear brown spores.
This genus differs from Arcyria in the capillitium springing from numerous points of the sporangial wall.
Capillitium of slender tubules, quite variable in thickness, proceeding from numerous points of thesporangial wall.
Capillitium proceeding from the inner surface of the sporangial wall, forming a complicated network, the threads extremely variable in thickness, minutely warted and spinulose.
Capillitium of long and very slender tubules, proceeding from numerous points of the sporangial wall, loosely branched, forming no evident network, the surface minutely warted or spinulose.
Capillitium of slender tubules quite variable in thickness, proceeding from numerous points of the sporangial wall and forming a complicated network, the surface minutely warted or spinulose.
Capillitial threads transverse to the sporangial cavity, attached usually at each end, plain or only slightly roughened Dianemaceae B.
Outer sporangial wall cartilaginous, the inner less distinct, or concrete with the outer; species oftener stipitate Leangium A.
According to the nature of the sporangial wall, the species fall rather naturally into two sections:-- A.
At the time of sporangial formation the protoplasm with numerous nuclei streams into the swollen end of the sporangiophore and there becomes cut off by a cell-wall to form the sporangium.
The sporangial frustules vary in shape and size, some being long and slender, others clavate, but they are all more or less tumid in the middle, with costae more indefinite than in perfect valves.
On the slide of Peronia are frustules exactly similar to certain of the sporangial variations of M.
It would seem, therefore, that the non-constricted form is a passage from the sporangial to the smaller or adult form, or is of no specific importance.
In conjugation, two frustules form two cylindrical bodies which later become conical and from which are formed the sporangial valves twice the usual size.
The usual method is the union of two frustules, which, throwing off the old valves, coalesce into a single mass of protoplasm which produces an auxospore, sometimes called a sporangial frustule.
Reproduction by zoospores formed of the whole contents of a cell, with a crown of numerous cilia; resting spores formed in sporangial cells after fecundation by ciliated spermatozoids formed in antheridial cells.
Fructification: by zoospores, either single or very numerous, and by resting spores formed in sporangial cells after the contents have been impregnated by the contents of autheridial cells of different forms.
Some of the cells enlarged, and then forming either vesicular empty cells or densely filled sporangial cells.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "sporangial" in a variety of sentences. We hope that you will now be able to make sentences using this word.
