Ascomycota

Belongs within: Opisthokonta.Contains: Trichoconis, Foveostroma, Taphrinales, Saccharomycetales, Pezizales, Orbiliaceae, Geoglossaceae, Sordariomyceta, Eurotiomycetes, Lecanoromycetes, Xylonales, Dothideomyceta, Lichinales. The Ascomycota are a diverse group of often multicellular fungi in which sexually-produced spores develop within saccate asci. Asci may or may not be associated with visible fruiting bodies (ascomata). The majority of ascomycetes are small with only a limited… Continue reading Ascomycota

Saccharomycetales

Belongs within: Ascomycota.Contains: Endomycetaceae, Stephanoascales, Dipodascaceae, Metschnikowia, Phaffomycetaceae, Candida, Pichia, Eremotheciaceae, Saccharomyces. The Saccharomycetales are a clade of fungi mostly existing as yeasts. Their morphology is correspondingly simple so taxa are primarily identified by chemical and/or molecular data. Phylogenetically basal taxa often have cell walls containing glucose, mannose and galactose whereas more derived taxa contain glucose and mannose alone Schweigkofler… Continue reading Saccharomycetales

Pichia

Belongs within: Saccharomycetales. Pichia is a somewhat loosely defined genus of yeasts reproducing by multilateral budding from a narrow base. In a Pichia Published 8 October 2015 In my previous post, I alluded to the revolutionary effect that DNA analysis had on the classification of bacteria. A similar thing happened for the study of yeasts. Previously,… Continue reading Pichia

Metschnikowia

Belongs within: Saccharomycetales. Metschnikowia is a genus of yeasts reproducing by multilateral budding, and producing elongate asci containing one or two needle-like spores. A barely pronounceable yeast Published 7 November 2007 “Yeast” is, admittedly, not one of the most tasteful-sounding words in the English language (it’s right up there with “moist” and “sphagnum” in the category… Continue reading Metschnikowia

Asterinaceae

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

Saccharomyces

Microthyriaceae

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

Dothideales

Belongs within: Dothideomyceta.Contains: Dothideaceae. The Dothideales are a group of fungi living as saprobes or necrotrophic parasites of plants (Kirk et al. 2001). Interascal tissue is absent, with no sterile cells or hyphae in the stroma. Members include the Dothioraceae, in which ascomata are immersed to erumpent with a thick peridium of large pseudoparenchymatous cells (Kirk et al. 2001).… Continue reading Dothideales

Parmulariaceae

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

Pezizaceae

Belongs within: Pezizales. The Pezizaceae are a group of fungi saprobic on soil, dung or very rotten wood, producing relatively large fruiting bodies (Kirk et al. 2001). Characters (Kirk et al. 2001): Ascomata large, apothecial or cleistothecial, formed from a single ascogonium or ascogonial coil, some shade of brown, violaceous, yellow etc. (without carotenoid pigments), usually sessile, flat or cupulate, without… Continue reading Pezizaceae
