A synopsis of the biology of the Ascomycotina

A synopsis of the biology of the Ascomycotina. A wide variety of classifications of the Ascomycotina has been proposed but a consensus is being reached on the main orders that it is appropriate to recognize. Most of these orders are well characterized with respect to their ecology and nutritional requirements although defined primarily on morphology. The 43 orders are displayed diagrammatically to illustrate their host and substratum requirements. This display is intended to stimulate argument and research by broadening the consideration of evolutionary pathways to include ecological and nutritional factors. It will also be of value as a teaching aid; overlays can be constructed to show additional features not treated here.
