Abstract

The development of the pink fungus stages showed that among the five stages, cobweb stage is the most important, since this stage may form the other four stages. I. Cobweb stage, develops following the germination of either basidiospores or conidia both on exposed and shaded side of branches. II. Pseudonodular stage, develops from symphogenous aggregation of cobweb stage mycelia on the surface of lenticel or cracks on shaded bark. III. Teleomorph, develops in two ways: a. Teleomorph incrustation develops from cobweb stage mycelia through four layers: basal layer, intermediate layer, subhymenial layer, and hymenial layer; b. Teleomorph pustule, develops from pseudonodular stage, through four layers, mirror to teleomorph incrustation. IV. Nodular stage, develops from meristogenous aggregation of cobweb stage mycelia on exposed bark. V. Anamorph, develops in two ways: a. From nodular stage; b. From cobweb stage mycelia on exposed bark.

Abstract

In the complete life cycle of pink fungus, in this study five stages were recognized as follows: stage I (cobweb stage), stage II (pseudonodular stage), stage III (teleomorph), stage IV (nodular stage), and stage V (anamorph). The five stages are arranged into a sexual cycle (I, II, and III) on shady side of a branch, and asexual cycle (I, IV, and V) on exposed side of a branch. Most of the pink fungus on the 23 plant species found in this study formed only two or three stages of the sexual cycle. Only on apple, lime, calliandra, cinchona, coffee, oleander, crotalaria, and tephrosia, may the fungus form the complete five stages.
