Abstract
Artillery fungi have been studied scientifically since 1729. For the nearly 3 centuries since, most publications dealing with artillery fungi were mycological
studies. However, in the latter half of the 20th century, this mycological curiosity became of serious concern to homeowners in many parts of the USA, where
artillery fungi grow on foundation landscape mulches, which are often comprised of shredded recycled wood. Such mulch is often colonized by artillery
fungi, which can propel their sticky spore masses (gleba) towards sides of houses covered with highly reflective light-colored siding. The sticky gleba adhere
tenaciously to vinyl siding and are very difficult to remove. If they can be removed, they often leave behind a brown stain. In this review, we examine the
efforts to control this pest in landscape mulch, many of which have been ineffective in the USA. However, one promising “green” sustainable solution is to mix
used recycled mushroom compost into the landscape mulch. Used mushroom compost may contain micro-organisms that are antagonistic towards artillery
fungi. This control effort may result in a substantial reduction of artillery fungus populations, thus minimizing sporulation.
