Many of the asexual states were formerly classified in the coelomycete genus ''Cryptosporiopsis''.
==Morphology==
Sexual states are often associated with cankers on bark, and are leathery black, brown, grey, or reddish apothecia about 1–2 mm diam. that usually lack a stipe, and have 8-spored cylindrical to club-shaped asci, often with an apical ring, and ellipsoidal to curved 1-celled, hyaline ascospores that sometimes germinate and produce conidia from phialides. Asexual states have stromatic coelomycetous conidiomata (which are often sporodochium-like when growing in agar culture) with slimy, cylindrical, ellipsoidal or fusiform 1-celled macroconidia and/or 1-celled cylindrical microconidia.<ref name=Verkley1999></ref>
==Ecology and pathology==
Most ''Neofabraeae'' species are temperate and associated with living trees; they often sporulate or make cankers on recently killed or fallen branches, or are isolated as endophytes from living branches or roots. Some species are weak bark, leaf or root pathogens.
Some ''Neofabraea'' species are serious plant pathogens in apple and pear orchards around the world that canker-bearing trees are usually removed.<ref name=Verkley1999></ref> ''Neofabraea malicorticis'', ''N. perennans'' and ''N. keinholzii'' cause apple anthracnose and post-harvest bull's eye rot. Bull's eye rot is somewhat amenable to control by fungicides, but effectiveness varies by species.<ref>{{cite journal |last1=Spotts |first1=RA |last2=Seifert |first2=KA |last3=Wallis |first3=KM |last4=Sugar |first4=D |last5=Xiao |first5=CL |last6=Serdani |first6=M |last7=Henriquez |first7=JL |title=Description of Cryptosporiopsis kienholzii and species profiles of Neofabraea in major pome fruit growing districts in the Pacific Northwest USA. |journal=Mycological Research |date=2009 |volume=113 |issue=11 |pages=1301–1311|doi=10.1016/j.mycres.2009.08.013 |pmid=19733662 }}</ref> Conventional and multiplex PCR assays for several species are available, derived from TUB2 (beta-tubulin) sequences.<ref>{{cite journal |last1=Gariépy |first1=TD |last2=Lévesque |first2=CA |title=Species specific identification of the Neofabraea pathogen complex associated with pome fruits using PCR and multiplex DNA amplification |journal=Mycological Research |date=2003 |volume=107 |issue=5 |pages=528–536|doi=10.1017/S0953756203007810 |pmid=12884949 }}</ref>
