Echinostelida
The Echinosteliales are an order of Amoebozoa in the class Myxomycetes. It contains two families, the Clastodermataceae and the Echinosteliaceae. Echinosteliales was circumscribed by George Willard Martin George Willard Martin (October 27, 1886 – September 11, 1971) was an American mycologist. He was born in Brooklyn, New York. He received a bachelor of literature degree in 1912, and a Master of Science degree in 1915, both from Rutgers Universit ... and published in 1961.

Biological Life Cycle
In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.Dixon, P.S. 1973. ''Biology of the Rhodophyta.'' Oliver & Boyd. Life cycles that include sexual reproduction involve alternating haploid (''n'') and diploid (2''n'') stages, i.e., a change of plo ...

Barbeyella Minutissima
''Barbeyella minutissima'' is a slime mould species of the order (biology), order Echinosteliales, and the only species of the genus ''Barbeyella''. First described in 1914 from the Jura mountains, its habitat is restricted to montane ecology, montane spruce and spruce-fir forests of the Northern Hemisphere, where it has been recorded from Asia, Europe, and North America. It typically colonises slimy, algae-covered logs that have lost their bark and have been partially to completely covered by liverworts. The sporangia are roughly spherical, up to 0.2 mm in diameter, and supported by a thin stalk up to 0.7 mm tall. After the spores have developed, the walls of the sporangia split open into lobes. The species is one of the smallest members of the Myxogastria and is considered rare. Taxonomy and classification The species was first species description, described in 1914 by Charles Meylan on the basis of a collection made at an altitude of from the Swiss Jura Mountains, ...
