It is believed that spores infect a host by entering a wound of a young twig. The fungus then spreads to branches and to the trunk. The galls do not kill the host but reduce vigor and girdle small branches causing dieback. Uninfected trees may occur near heavily infected ones.<\/p>\n<p>Galls may occur singly or in clusters on the trunk and branches. They are woody, rough, more or less round swellings. They appear as tight clusters of nodules. They can be very small to 10\u2033 in diameter. If cut open they reveal disorganized woody tissue but no insect chambers or tunnels.<\/p>\n<p><a href=\"http:\/\/minnesotaseasons.com\/Fungi\/Phomopsis_gall_on_hickory.html\" target=\"_blank\">http:\/\/minnesotaseasons.com\/Fungi\/Phomopsis_gall_on_hickory.html<\/a><\/p>\n<div class=\"fcbkbttn_buttons_block\" id=\"fcbkbttn_left\"><div class=\"fcbkbttn_like \"><fb:like href=\"https:\/\/blog.minnesotaseasons.com\/?p=684\" action=\"like\" colorscheme=\"light\" layout=\"button_count\"  size=\"small\"><\/fb:like><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>There are at least 232 species of the fungus Phomopsis.
