Phlyctema vagabunda Desm. 1847

We can readily distinguish Neofabraea from Phlyctema based on their asexual morphs. Phlyctema species have eustromatic conidiomata, fusiform macroconidia, and filiform microconidia, while all the known Neofabraea species form acervular conidiomata, macroconidia that vary in shape (cylindrical-fusiform, allantoid to ellipsoid), and shorter microconidia.
Neofabraea was protected over Phlyctema ( Johnston et al. 2014), because the type species, Ph. vagabunda, was considered a member of Neofabraea, making Phlyctema a synonym of Neofabraea. However, the present study proved that these two genera are not taxonomically congruent (see below); therefore, Phlyctema and Neofabraea are accepted as distinct genera.
It is suggested by Brook (1957) that this fungus had been previously recorded by Taylor and Brien (1943) as Neofabraea malicorticis (Cordley) Jackson; he showed that together with Pezicula malicorticis it is responsible for ripe spot on apple fruits; it overwinters on trees as a dieback on small stubs left after pruning. Padfield and Cooper (1965) showed that storing fruit at temperatures a little above freezing held up the development of the fungus for 120-180 days. In some seasons, especially when fruit has been picked late in the season, it is an important pathogen.
