Order Sphaeriales: 225 genera, 1300 species. Dark, crusty, globose to pear-shaped individual perithecial ascomata with prominent ostioles. OR many perithecial cavities immersed in a single stroma to form a compound fructification, as in Xylaria below The asci often have an apical ring or sphincter, which is usually, though not always, amyloid (stains blue in iodine). Thread-like, sterile elements called paraphyses are present between the asci in the hymenium of some members, absent from others Ascospores can be light or dark, simple or septate, with or without germ pore or slit, sometimes with gelatinous sheaths or appendages.

Nature 422, 859 - 868 (24 April 2003); doi:10.1038/nature01554 The genome sequence of the filamentous fungus Neurospora crassa Neurospora crassa is a central organism in the history of twentiethcentury genetics, biochemistry and molecular biology. Here, we report a high-quality draft sequence of the N. crassa genome. The approximately 40-megabase genome encodes about 10,000 proteincoding genes—more than twice as many as in the fission yeast Schizosaccharomyces pombe and only about 25% fewer than in the fruitfly Drosophila melanogaster. Analysis of the gene set yields insights into unexpected aspects of Neurospora biology including the identification of genes potentially associated with red light photobiology, genes implicated in secondary metabolism, and important differences in Ca2+ signalling as compared with plants and animals. Neurospora possesses the widest array of genome defence mechanisms known for any eukaryotic organism, including a process unique to fungi called repeat-induced point mutation (RIP). Genome analysis suggests that RIP has had a profound impact on genome evolution, greatly slowing the creation of new genes through genomic duplication and resulting in a genome with an unusually low proportion of closely related genes. Order Hypocreales: 80 genera, 550 species. This order is recognized by its brightly coloured, simple or compound, perithecial ascomata -- usually yellow, orange or red -- which are fleshy or waxy in texture, and usually borne on supporting layers of mycelium (subicula) or in stromata. Four genera are especially well-known. Nectria (27 spp) has bright red, superficial perithecia (right) containing 2-celled (didymosporous) ascospores. Some species cause cankers and die-backs of trees. Below: commonly encountered anamorph, Tubercularia, causes “coral spot”.Nectria species can cause cankers and die-backs of trees.
