Description of Cryptosporiopsis kienholzii and species profiles of Neofabraea in major pome fruit growing districts in the Pacific Northwest USA.

The objectives of this study were i) to give a taxonomic description of a fungus phylogenetically related to Neofabraea and assign the name Cryptosporiopsis kienholzii to this fungus, ii) to expand previous Neofabraea species profiles from infected apple and pear fruit collected from major pome fruit production districts in Oregon and Washington, and iii) to determine the sensitivity of Neofabraea alba, Neofabraea malicorticis, Neofabraea perennans, and C. kienholzii to a range of fungicides. A name is given herein to the anamorph of the fungus previously called 'Neofabraea sp.

Effects of culture media and environmental factors on mycelial growth and pycnidial production of Potebniamyces pyri.

Potebniamyces pyri (anamorph Phacidiopycnis piri) is the causal agent of Phacidiopycnis rot of apples and pears. The disease has recently been recognized in pears in the USA. Little information on the basic biology of the fungus is available.
