| Popis: | International audience; From a survey of arbuscular mycorrhizal (AM) fungi in agro-ecosystems in Central Europe and West Africa, an undescribed species of Acaulospora was recovered and is presented here under the epithet Acaulospora sieverdingii. Spores of A. sieverdingii are 60-80 mu m in diam, hyaline to subhyaline to rarely light yellow and have multiple pitted depressions on the outer spore wall similar to those known for A. alpina, A. cavernata, A. paulinae and A. scrobiculata. The pits in A. sieverdingii are tiny and often irregular and resemble small dots (0.8-1.8 mu m) or lines (0.5-1.2 x 1.8-2.5 mu m). Analyses of the ITS1, 5.8S subunit and ITS2 regions of the rDNA resolved each of the five species in a monophyletic well-supported chide and indicate that A. sieverdingii is phylogenetically closer to A. paulinae, A. cavernata and A. denticulata than to A. scrobiculata. The new species is common in Central Europe only at altitudes below 800 m as1 where, to date, it has been detected in crop rotation systems and grasslands in Poland, Germany, France, Switzerland and Italy. Under these conditions it may co-occur with A. paulinae, A. cavernata, A. scrobiculata and several other Acaulospora spp. A. sieverdingii was also recorded from subtropical and tropical agro-ecosystems and consequently appears to be adapted to ecologically diverse environments. |
