Question:On our lawn there have suddenly appeared irregular shaped growths which are taffy-colored at first and later become black. When the lawn mower goes over the grass a fine black soot-like material blows over the lawn. Will you please tell me what this growth is and how to get rid of it?

Answer/Response:The soot-like development which you describe is one of the fungi known as slime mold. It is a superficial growth which grows on grass when the conditions of temperature and moisture are favorable for its development. The black dust-like material consists of very fine grains which are the spores and act as seed to propogate the fungus. Ordinarily the fungus grows in the soil and is not detected until it suddenly sends up the fruiting bodies which you have observed. At first these fruiting bodies may be the large irregular, light brown or grey masses or tiny steel grey bodies, sometimes hundreds of them on a single grass blade or clover leaf. Both types of fruiting bodies mature rapidly and break open, exposing the masses of black spores inside. When mowers run over these areas they spread the spores over a large area of turf. Ordinarily if you can take a hose at that stage you can risne this black dust off the rass and you will find that it causes no permanent damage to the grass.
