Helicodendron praetermissum sp.nov. and Spirosphaera carici-graminis sp. nov., aero-aquatic fungi on monocotyledonous debris

Two new species of aero-aquatic fungi, Helicodendron praetermissum sp.nov. and Spirosphaera carici-graminis sp.nov. are described and illustrated. They are compared with similar species. Because they were found exclusively on monocotyledonous plant remains submerged in small pools and ditches, their ecology and distribution is discussed. Key words: mitosporic fungi, hyphomycetes, aero-aquatic fungi, Helicodendron praetermissum, Spirosphaera carici-graminis.
