PP-54: Ganoderma Butt Rot of Palms
Figure 3. Three phases of basidiocarp (conk) development of Ganoderma zonatum. The white "button" near the top of the picture is the beginning stage of the conk. The lower-right structure is a mature conk. The lower-left structure is also a mature conk, but it is an old one; the underside of this conk is no longer white.
