Category: Dothideomyceta

Belongs within: Dothideomyceta. The Asterinaceae are a primarily tropical family of fungi biotrophic on leaves (Kirk et al. 2001). Characters (Kirk et al. 2001): Mycelium superficial, often hyphopodiate. Ascomata round or elongate, strongly flattened, either opening by radiating or longitudinal splits, or by a lysigenous pore; peridium usually composed of radiating isodiametric cells; hymenium often gelatinous, J+ blue. Interascal tissue absent.… Continue reading Asterinaceae

Belongs within: Dothideomyceta. The Microthyriaceae are a family of saprobic or epiphytic fungi with strongly flattened, superficial ascomata (Kirk et al. 2001). Characters (Kirk et al. 2001): Superficial mycelium indistinct. Ascomata small, strongly flattened, superficial, with small central ostiole sometimes surrounded by thickened tissue; peridium brown, composed of radiating rows of irregular, epidermoid or more or less isodiametric cells, basal layer… Continue reading Microthyriaceae

Belongs within: Dothideomyceta. The Parmulariaceae are fungi biotrophic on leaves and stems (Kirk et al. 2001). Characters (Kirk et al. 2001): Superficial mycelium absent. Ascomata superficial or subcuticular, developing from more deeply immersed stromatic layer, sometimes as locules in compound structure, strongly flattened, discoid or pulvinate, often elongate, opening by irregular disintegration or longitudinal splits; peridium composed of one or few… Continue reading Parmulariaceae

Belongs within: Ascomycota.Contains: Arthoniaceae, Roccellaceae, Pleosporomycetidae, Asterinaceae, Microthyriaceae, Schizothyriaceae, Parmulariaceae, Parodiopsidaceae, Saccardiaceae, Strigulaceae, Capnodiales, Myriangiales, Dothideales. The Dothideomyceta are a diverse clade of fungi with fissitunicate asci (Schoch et al. 2009). The larger number of representatives are included within a Dothideomycetes, in which ascomata are formed lysigenously from stromatic tissue, asci usually lack apical structures, and anamorphs are hyphomycetous… Continue reading Dothideomyceta

Belongs within: Dothideomyceta.Contains: Mycosphaerellaceae. The Capnodiales are a group of sooty moulds, most of which are epiphytic (Kirk et al. 2001). Characters (Kirk et al. 2001): Mycelium superficial, well-developed, dark, very varied in form, composed of sometimes irregular, more or less cylindrical or torulose hyphae, sometimes with erect branches, sometimes with mucous coating. Ascomata small, globose or vertically elongated, thin-walled, sometimes covered… Continue reading Capnodiales

Belongs within: Pleosporomycetidae. The Trypetheliaceae are a lineage of crustose lichens bearing globose ascomata (Kirk et al. 2001). Characters (Kirk et al. 2001): Thallus crustose, often poorly developed or immersed. Ascomata globose, sometimes aggregated within pseudostromatic tissues, papillate, the ostiole sometimes lateral. Interascal tissue of narrow branched and anastomosed trabeculate pseudoparaphyses. Asci cylindrical, fissitunicate, with wide ocular chamber, without refractive ring,… Continue reading Trypetheliaceae

Belongs within: Capnodiales.Contains: Passalora, Pseudocercospora, Cladosporium, Cercospora. The Mycosphaerellaceae are a group of often plant-pathogenic fungi including the genus Cercospora and related taxa, commonly associated with spot formation on leaves. Mycosphaerella graminicola is the cause of septoria leaf spot, one of the most significant diseases of wheat. <==Mycosphaerellaceae [Mycospherellales, Mycosphaerellineae] |–+–Davidiella tassianaSS09 [=Mycosphaerella tassianaKC01; incl. Cladosporium herbarumSS09]… Continue reading Mycosphaerellaceae

Belongs within: Pleosporomycetidae.Contains: Zopfiaceae, Melanommataceae, Didymosphaeriaceae, Sporormiaceae, Lophiostomataceae, Pleosporaceae, Phaeosphaeriaceae, Leptosphaeriaceae, Cucurbitariaceae, Didymellaceae, Dacampiaceae, Montagnula. The Pleosporales are a clade of microfungi producing black, often thick-walled ascomata (Kirk et al. 2001). Characters (Kirk et al. 2001): Thallus or stroma absent or rarely poorly developed. Ascomata perithecial or rarely cleistothecial, sometimes clypeate, variable in form but usually more or less globose, thick-walled, immersed or… Continue reading Pleosporales
