Survey over the fungi which causes diseases in plants (Danish conditions).
(Choosing the links will give you further information.)
It shall bee emphasized, that the dividing of fungi to different divisions, subdivisions, classes, subclasses, families, species and genus......, not always is quite right.
New ways to categorizing and placing fungi in a systematic system is still coming on. In the latest years, by means of molecular work and genetic tools, scientist has done great progress finding the right groups.
As an example, the oomycetes are not longer at part of the fungal system, but now moved to the group called the Chromistra, which is a subgroup under the Pseudofungi.
Another example: the main part of fungi earlier belonging to the class Deuteromycetes (Fungi imperfecti) is now categorized as Ascomycetes.
