Aliasgharzad N, Martensson LM, Olsson PA (2010) Acidification of a sandy grassland favours bacteria and disfavours fungal saprotrophs
as estimated by fatty acid profiling.
Among them there are obligate parasites, facultative saprotrophs and facultative parasites.
The most popular species of polypores on living English oaks in coppice oakeries of South-Western Central Russian Upland are facultative saprotrophs.
sulphureus combines properties of both facultative saprotroph and facultative parasite .
Fungi are heterotrophs requiring external sources of carbon for energy and cellular synthesis and they have adapted three different modes of nutrition to obtain this carbon, occurring as saprotrophs, necrotrophs and biotrophs.
Mycorrhizal fungi were spatially separated from saprotrophs, which almost exclusively occupied the upper fresh and partially decomposed litter layers (Lindahl et al.
2001) showed competitive sequestration of phosphorus between a saprotroph, Hypholoma fasciculare and an ECM fungus, Suillus variegatus and concluded that the potential for either fungus to out-compete depended on the carbon source available to either competitor.
They are saprotrophs and semi-saprotrophs (facultative parasites), and are characterized by polytrophy, but at the same time they are distinguished by substrate specificity.
Also the last two species belong to the ecological group of saprotrophs [4, 6, 9].
