Also in the common gray mould of infusions and preserves, Penicillium, by a process which is perhaps intermediate between budding and cell-division, a cell at the end of a hypha constricts itself in several places, and the constricted portions become separate as _conidiospores_.
Saprophytic bacteria can readily make their way down the dead hypha of an invading fungus, or into the punctures made by insects, and Aphides have been credited with the bacterial infection of carnations, though more recent researches by Woods go to show the correctness of his conclusion that Aphides alone are responsible for the carnation disease.
Compartments before (A, E) and after (B-D, F-H) dissection of a hypha with a closed (A-D) and an open (E-H) septum.
Plugging of a septal pore depends on its position in the hypha and the presence of glucose in the medium.
(C) Magnification of boxed area in (A) and (B) showing a hypha with the first and second septum as referred to in the text.
A common thought for 50 years has been that the hypha direct their growth to the apex of their cell through outward flow of growth material forming a longer and longer blimp-like shape.
"We think the hypha is recycling material," he said.
Growth of the fungi is confined to the apex or end of the hypha cell.
A closer look shows that fungi are made of thread-like cells called hypha.
But Shaw found that there is a region of the cell at the growing apex of the hypha that directs material inward.
