Structure of Rhizopus spp. - Scheme drawing
|Honorary ex Corda|
Rhizopus cultures form a cobweb-like mushroom lawn with flat runners. At the points where rhizoid hyphae are anchored in the substrate , there are densely tufted, unbranched, brownish and up to 3 millimeter long sporangia carriers .
The spores are more or less oval, between 10 and 15 micrometers long and 6 to 8.5 micrometers wide.
Rhizopus species can be found on rotting parts of plants and in the soil. The spores are common in the air and spread quickly. Rhizopus nigricans in particular often affects food.
In Germany only four species are common, but very common. Many other species are found in the tropics.
From a morphological point of view, the genus can be divided into three groups; a molecular biological study from 2006 essentially confirmed these three groups. These are:
- the oryzae group, with:
- the microsporus group, with:
- and the stolonifer group, with:
