Abstract

The Ustilaginales represent a group of fungi which are all parasitic upon the higher flowering plants. The mycelium is hyaline, somewhate septate, mostly intercellular, branched, and practically restricted to the interior of the host. At maturity the mycelium often disappears, partially, at least, through gelatinization. The fertile mycelia becomes compacted into the masses which give rise to numerous chlamydospores. That is, the chamydospores develop directly from the mycelia. Upon germination, each chlamydospore sends out a short tube called a promycelium. From the promycelium are budded off sporidia, generally four. If the sporidia find logment on suitable host tissue, they germinate and cause infection.
