	~~'''~~Dothideomycetes''' is the largest and most diverse class of [[Ascomycota]] fungi. It comprises 11 orders, 90 families, 1300 genera and over 19,000 known species. This class includes many plant pathogenic fungi, lichens, and other ecologically important species.		{{DISPLAYTITLE:Dothideomycetes}}

	== ~~Taxonomy~~ ==		== Overview ==
			[[File:Apple_scab_SEM.jpg\|thumb\|right\|Scanning electron micrograph of apple scab, a disease caused by a member of Dothideomycetes.]]
	~~The class~~ Dothideomycetes is ~~divided into two subclasses:~~ [[~~Dothideomycetidae~~]] ~~and~~ [[~~Pleosporomycetidae~~]]. ~~The former~~ includes ~~the orders~~ [[~~Capnodiales~~]], [[~~Dothideales~~]], ~~[[Hysteriales]]~~, and ~~[[Myriangiales]], while the latter includes [[Pleosporales]]~~.		'''Dothideomycetes''' is the largest and most diverse class of [[ascomycete]] fungi within the phylum [[Ascomycota]]. This class includes a wide variety of fungi that are primarily characterized by their production of [[ascospores]] in a structure known as an [[ascoma]]. Dothideomycetes are known for their ecological diversity, with species found in a range of habitats including terrestrial, aquatic, and symbiotic environments.

	~~== Characteristics ==~~

	Dothideomycetes ~~species~~ are typically ~~characterized by their asci, which are~~ bitunicate, meaning they have ~~two layers~~. The ~~outer layer~~ is ~~designed to build up turgor pressure~~ to ~~forcibly discharge the ascospores, while the inner layer houses the ascospores~~.		== Morphology ==
			Dothideomycetes exhibit a wide range of morphological forms. The fruiting bodies, or [[ascomata]], can be [[perithecial]], [[pseudothecial]], or [[apothecial]]. The [[asci]] are typically bitunicate, meaning they have a double wall, which is a distinguishing feature of this class. The ascospores are often darkly pigmented, which is thought to provide protection against [[ultraviolet radiation]].

	== Ecology ==		== Ecology ==
			Members of Dothideomycetes play significant roles in various ecosystems. They can be [[saprotrophic]], breaking down organic matter, or [[pathogenic]], causing diseases in plants and animals. Some species form [[lichen]]s, while others are involved in [[endophytic]] relationships with plants. A notable example of a plant pathogen in this class is the fungus responsible for [[apple scab]], a disease that affects apple trees and is of economic importance in agriculture.
	Dothideomycetes ~~are found~~ in ~~a wide range of habitats~~, ~~including soil~~, ~~plant debris~~, and ~~as endophytes in plant tissues~~. ~~Many~~ species are ~~also found~~ in ~~aquatic environments~~. ~~Some species are pathogenic to plants~~ and ~~can cause significant crop losses~~.

	== Economic Importance ==		== Economic Importance ==
			[[File:Apple_scab_SEM.jpg\|thumb\|left\|Close-up of apple scab lesions on a leaf.]]
			Dothideomycetes include several species that are important in agriculture and industry. Plant pathogens such as those causing [[apple scab]] and [[black spot]] on roses can lead to significant crop losses. Conversely, some species are beneficial, being used in the production of [[enzymes]] and [[bioactive compounds]] for pharmaceuticals.

	~~Several species of~~ Dothideomycetes ~~are of economic importance due to their role as plant pathogens. For example~~, ~~species in the genus~~ [[~~Mycosphaerella~~]] ~~cause leaf spot diseases in a variety of crops~~, ~~while~~ [[~~Venturia inaequalis~~]], ~~the cause~~ of ~~apple scab~~, ~~is a member~~ of ~~the~~ Dothideomycetes.		== Taxonomy ==
			The class Dothideomycetes is divided into several orders, including [[Capnodiales]], [[Pleosporales]], and [[Dothideales]]. Each order contains a variety of families and genera, reflecting the diversity within the class. The taxonomy of Dothideomycetes is complex and subject to ongoing research and revision as new molecular data become available.

'''Dothideomycetes''' is the largest and most diverse class of [[Ascomycota]] fungi. It comprises 11 orders, 90 families, 1300 genera and over 19,000 known species. This class includes many plant pathogenic fungi, lichens, and other ecologically important species.

== Taxonomy ==

The class Dothideomycetes is divided into two subclasses: [[Dothideomycetidae]] and [[Pleosporomycetidae]]. The former includes the orders [[Capnodiales]], [[Dothideales]], [[Hysteriales]], and [[Myriangiales]], while the latter includes [[Pleosporales]].

== Characteristics ==

Dothideomycetes species are typically characterized by their asci, which are bitunicate, meaning they have two layers. The outer layer is designed to build up turgor pressure to forcibly discharge the ascospores, while the inner layer houses the ascospores.

== Ecology ==

Dothideomycetes are found in a wide range of habitats, including soil, plant debris, and as endophytes in plant tissues. Many species are also found in aquatic environments. Some species are pathogenic to plants and can cause significant crop losses.

== Economic Importance ==

Several species of Dothideomycetes are of economic importance due to their role as plant pathogens. For example, species in the genus [[Mycosphaerella]] cause leaf spot diseases in a variety of crops, while [[Venturia inaequalis]], the cause of apple scab, is a member of the Dothideomycetes.
