On the other hand, conidia of the related Apiognomonia errabunda do infect leaves of its host, Fagus sylvatica and can persist in them as endophytes (Viret and Petrini, 1994). 1918, Gnomonia erythrostoma (Pers.)

The early spotting of leaves and fruits of Prunus species, particularly cherry and apricot [Prunus armeniaca], can result in significant defoliation and loss of yield in certain years when weather conditions are favourable for infection by airborne ascospores. Distribution Maps of Plant Diseases. Incidence of fungal diseases on leaves of apricot and plum cultivars in Hungary. Hecht and Zinkernagel (2006) provide some initial data towards a model for prediction of spore release and infection that would guide appropriate and timely application of protective chemicals in the spring.

Two species cause a “shot-hole” symptom, in which the necrotic tissue in limited spots dries and falls out of the leaf. Valiuskaite A, 2002. A. erythrostoma is a perithecial ascomycete known primarily from Europe, although it has also been reported from eastern Asia. Ascospores are ejected from perithecia after rain (Hecht and Zinkernagel, 2006) and disseminated by wind (Sanchez and Becedas, 2007). Prunus species are subject to quarantine for the more threatening plum pox virus (USDA/APHIS, 2008; DAFF, 2009). Ellis MB; Ellis JP, 1997.

Leaves were first infected near the end of May, and fruit were first infected in mid-June, in one year, but earlier in the spring the next year. The spots turn yellow to red, depending on the tree variety. Wallingford, UK: CABI, CABI, Undated b. CABI Compendium: Status as determined by CABI editor.
