Placopsis ("bull's-eye lichen") exhibits a preference for basaltic/andesitic rock. It is especially well developed when growing on trees near creeks and rivers. Members of the genus have roughly circular fruiting discs with rims that have photosynthetic tissue similar to that of the nonfruiting part of the lichen body (). Soil moisture is a critical factor in apothecia production and is one of the principal reasons that ascospore-initiated diseases are associated with irrigation events or periods of high rainfall. The aim of this paper is to review recent advances in understanding the pathophysiology and molecular mechanism of androgenetic alopecia. Since most growers have done a good job of controlling mummy berry in past years, the number of apothecia in blueberry fields will generally be low Sclero-cast is a new tool to aid growers and consultants in identifying high risk conditions for white mold development in soybeans.
