Ceratiomyxa fruticulosa , also known as antler-shaped slime mold in German-speakingcountries, is a slime mold from the Protosporangiida groupthat is widespread worldwide.
features
The fructifications ( sporophores ) are white, also hyaline or yellow, rarely also bluish in color. Externally, they appear frosted due to the spores formed on the surface. They stand in tightly packed groups that are often ten centimeters or more spread out. The individual columns are one to ten millimeters high, 0.3 millimeters wide at the base and taper towards the top. Sometimes they are branched into up to five limbs, which gives them an antler-shaped appearance. The membranous underlay ( hypothallus ) on the substrate surface connects the entire group with one another. The hypothallus is colored white and tears open into small fields when it is dry.
Close up of the fructifications
Yellow variant
The spores are located on the outside of the surface of the fructifications on stems about 7 to 20 micrometers long and 1.5 to 3 micrometers thick. The spores themselves are broadly elliptical, teardrop-shaped or round and measure 8–15 × 6–10 micrometers. They are colorless to pale green-yellow and have a granulated content. The plasmodium is watery white to yellow.
ecology
In Central Europe, the slime mold fructifies mainly from late spring to summer on hardwood and coniferous wood, especially on old stumps. It is often found primarily after short periods of moisture. Ceratiomyxa fruticulosa is associated with the blood milk fungus , the wasp's nest , Trichia varia , Arcyria pomiformis , Didymium ovoideum and species of the genus Cribraria .
distribution
Ceratiomyxa fruticulosa is widespread worldwide and is probably the most common slime mold of all. It can be found from the Arctic to the tropics .
Systematics
Ceratiomyxa fruticulosa has at least two variations, but their justification has not yet been established.
The var. Porioides has poroid fructifications that extend flat on the substrate. The pores are between 0.1 and 0.5 millimeters in size. The variation is also widespread, at least in Central Europe. Microscopically it cannot be distinguished from var. Fruticulosa . However, the var. Porioides on a common hypothallus with the var. Fruticulosa be encountered; both can merge into one another.
The var. Descendens is mainly known from Japan, but is also found in France and Taiwan. The fructifications consist of individual unbranched columns that are on a polygonal base. However, both variations can be found in all transitional forms. Hence this variation does not seem to be justified as such.
Similar species
Ceratiomyxa fruticulosa can hardly be confused with other species. If in doubt, it can be identified by its slimy consistency.
