Ceratiomyxa is a genus of slime molds that,together with its sister taxon, the Protosporangiidae , forms the group of Protosporangiida .

features

The species of the genus Ceratiomyxa form columnar, twig or morel-like fructifications that are on a common base ( hypothallus ). Unlike most slime molds, the spores are not located inside closed fruiting bodies ( sporocarpies ), but on the outside on thin stalks. The fructifications are therefore also referred to as sporophores. Quaduclear protoplasts form from the spores , from which eight haploid swarming cells are formed.

species

The genus Ceratiomyxa comprises four species, of which only Ceratiomyxa fruticulosa occurs in Central Europe:

Art	Distribution area	features
Ceratiomyxa fruticulosa ( OF Müll. ) T. Macbr.	Worldwide	Fructifications from individual, possibly branched, stalks, or poroid, one to ten millimeters high
Ceratiomyxa hemisphaerica L.S. Olive & Stoian.	United States	Fructifications hemispherical, about 100 to 200 micrometers in diameter and about 70 to 120 micrometers high, individually or connected to one another at the base, with about 20 to 120 micrometers long, thin stalks, at each end of which there is a spore.
Ceratiomyxa morchella A.L. Welden	Tropics and Subtropics of America	Morel-like fructifications, about two to three millimeters high
Ceratiomyxa sphaerosperma Boedijn	Tropics and subtropics of Central America and Israel	Fructifications consisting of small stalks, at the ends of which individual, rarely branched branches arise in tufts, on which the spores are located.
