Members of Oomycetes are found to grow in both fresh water and salt water as well as in terrestrial habitat. The holocarpic thalli are endobiotic and converted into a zoosporangium. Though members of fungi show similarity in their morphology, mode of nutrition and ecology, but the higher gungi is observed in the base sequences of their 18s rRNA or more precisely in the DNA coding for itwhich is now considered as the most important parameter to determine the genetic relationship.
All the three groups are placed under the Domain Eukaryota. His classification is based on septation of hypha and characteristics of spore. Answer Now and help others.

Cup-shaped ascocarp contains asci, arranged in parallel series …………………………………………………. See Kluge.
Introductory Mycology3rd ed, . Both are of slimy consistency, hence slime molds. Karyogamy occurs in basidium mother cell and forms diploid nucleus, which is ephemeral short lived. The characteristic spores of the sexual or perfect stage are endogenous in origin and are called the ascospores.
They are found profusely in the upper layer of humus in deciduous forests and in cultivated lands. Ainsworth is given: See below for more information. Nova plantarum genera iuxta Tournefortii methodum disposita. Characteristics of Fungi Ch. Endoparasitic Slime Molds Ch.
Thallus highly developed with distinct cell wall. See Brands. Cell divisions both mitotic and meiotic are intranuclear and centric i. Catalogus plantarum sponte circa Gissam nascentium. Based on the above fact and phylogenetic consideration, the entire fungal community are now segregated out and placed them under three different Kingdoms Fungi, Straminopila Chromista and Protozoa.
Order Agaricales – The Mushrooms Ch. This division comprises two subdivisions.

Vegetative fjngi is coenocytic and thalloid, either globose or ovoid structure, either an elongated simple hypha, or well, developed mycelium. See LindleyRendle. In eucarpic forms, the thalli may consist of a single reproductive organ bearing a branched rhizoidal system or may be polycentric with septate and branched hyphae.
