Cristulariella Depraedans
''Cristulariella depraedans'', commonly known as gray mold spot, sycamore leaf spot or bull's eye spot, is a fungal pathogen that affects maple trees (genus ''Acer'') and certain other woody and herbaceous species. In maples, the foliage becomes affected by small grey lesions which expand and coalesce, the leaves later wilting and falling from the tree early. The disease seems to be associated with cool wet summers, and epidemic years sometimes occur. Hosts The fungal pathogen ''Cristulariella depraedans'' is found in Europe and North America and mostly affects trees in the genus '' Acer''. Trees affected in Germany and Britain are primarily the sycamore ('' A. pseudoplatanus'') and the Norway maple ('' A. platanoides''), while in North America the most affected are ''A. platanoides'', the red maple ('' A. rubrum''), the sugar maple ('' A. saccharum''), the silver maple ('' A. saccharinum''), the mountain maple ('' A. spicatum'') and the vine maple ('' A. circinatum'').

Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acer Saccharum
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and eastern United States.
