Hypoxylon Canker Of Shade Trees
''Hypoxylon'' canker of shade trees is a weak ascomycete fungus that negatively affects growth and can eventually lead to the death of already dying or diseased host trees. There are many different species that affect different trees. For example, '' Hypoxylon atropunctatum'', a common species, is found on oak trees, '' Hypoxylon tinctor'' affects sycamore trees, and '' Hypoxylon mammatum'' infests aspen trees. Although the fungus is found on the majority of tree bark in an infested area, it only harms the tree when the tree becomes stressed or injured because it is easier to infect. Thus, ''Hypoxylon'' had an endophytic stage. An endophyte is an organism such as a bacterium or fungus that spends some of its life not causing disease to the host while being on it. When a stress or injury occurs, the fungus will infect and begin living off the nutrients of the tree. ''Hypoxylon'' infects trees throughout the United States, but a few notable wide-scale problems have occurred in Arka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypoxylon Mammatum Signs On Aspen
''Hypoxylon'' is a genus of ascomycetes commonly found on dead wood, and usually one of the earliest species to colonise dead wood. A common European species is ''Hypoxylon fragiforme'' which is particular common on dead trunks of beech. Based on morphological studies and gene sequence analyses, 27 species formerly assigned to ''Hypoxylon'' sect. ''Annulata'' were reassigned to a new genus called ''Annulohypoxylon'' in 2005. Research in Iran has shown the potential of some species of Hypoxylon in producing chemicals that are antagonistic against the disease Hymenoscyphus fraxineus, Ash dieback. Use in the cultivation of ''Tremella fuciformis'' Some species in the genus ''Hypoxylon'' may be used in the cultivation of ''Tremella fuciformis'', one of the foremost Medicinal mushrooms, medicinal and Edible mushroom, culinary fungi of China and Taiwan. ''Tremella fuciformis'' is a Parasitism, parasitic yeast that does not form an edible fruitbody without parasitizing another fungus ...
