ABSTRACT
During an excursion in the Landschaftspark Duisburg-Nord in 2009 and 2010 we were able to collect and identify more than 100 specimens of microfungi on different parts of cultivated and wild plant species. We found parasitic and saprophytic microfungi on trees, bushes and herbaceous plants. Some of them have been observed only rarely until now. Most of the collected microfungi species belong to the classes of Ascomycetes, Basidiomycetes and Deuteromycetes - for example Leptosphaeria modesta (Desm.) Rabenh. on Knautia cf. arvensis (L.) Coult., Ramularia urticae Ces. on Urtica dioica L., Stigmina glomerulosa (Sacc.) S. Hughes on Juniperus communis L., Pseudomassaria corni (Sowerby) Arx on Cornus alba L., Mollisia discolor (Mont.) W. Phillips on Cornus alba L., Botryosphaeria quercuum (Schwein.) Sacc. on Quercus robur L., Peronospora cytisi Rostr. on Laburnum anagyroides Med., Microsphaera guarinonii Briosi and Cavara on Laburnum anagyroides Med., Brachysporium dingleyae S. Hughes on Fraxinus angustifolia Vahl and Rhododendron spec., Mamiania fimbriata (Pers.) Ces. and De Not. on Carpinus betulus L., Atopospora betulina (Fr.) Petr. on Betula pendula Roth, Septoria robiniae (Lib.) Desm. (=Phloeospora robiniae (Lib.) Höhn.) on Robinia pseudoacacia L., Chalara hughesii Nag Raj and W.B. Kendr. on Quercus robur L.. All specimens are located in the Herbarium ESS, Mycotheca Parva collection G.B. Feige and N. Ale-Agha.

In June 2009 we organized a botanical student excursion to the eastern part of Sardinia, Italy. On this occasion we were able to collect and identify over 80 species of microfungi growing on higher plants. The collecting sites were spread over a large area, among them were La Caletta, Capo Comino, Monte Albo, Cala Gonone, Monte Maccione, San Teodoro, Capo Testa. The collected microfungi were parasitic or saprophytic; Basidiomycotina (Uredinales), Ascomycotina and Deuteromycotina (Hyphomycetes, Coelomycetes) were predominant. Examples are Pezicula corticola (Jörg.) NANNF. (new for Sardinia), on Pyrus communis. Puccinia chamaecyparissi TROTT. (new for Sardinia), on Santolina insularis. Sphaceloma oleae CICC. and GRANITI (new for Sardinia) and Phlyctema vagabunda DESM. (new for Sardinia), on Olea europaea and Arbutus unedo. Puccinia pseudosphaeria MONT. (new for Sardinia), on Sonchus oleraceus. Discula umbrinella (BERK. and BR.) SUTTON (new for Sardinia)(D. quercina WEST. and BARK), on Quercus coccifera. Zaghouania phillyreae PAT. (new for Sardinia), on Phillyrea angustifolia. Phymatotrichum omnivorum (DUGGAR) HENNEBERT, new on Verbascum thapsus for Sardinia. Guignardia punctoidea (COOKE) SCHROTER (new for Sardinia), on Quercus ilex. Many of the collected species are rare or unknown for the area of investigation until now. All specimens are located in the Herbarium ESS, Mycotheca Parva collection G.B. Feige and N. Ale-Agha.
