Occurrence of fungi of the genus Nectria s.l. (Ascomycota, Hypocreales, Bionectriaceae, Nectriaceae) in Slovakia

Abstract

In this work we present the recent data on occurrence of 22 fungal species belonging to the Nectria
genus s.l. – of families Bionectriaceae and Nectriaceae, the occurrence of which in Slovakia was
recorded in our survey and/or which were already recorded and published by other authors in the
past. For each individual species, we describe its ecological features and its significance in terms
of phytopathology. Sporadic occurrence has been found for the species Cosmospora coccinea, C.
purtonii, Hydropisphaeria peziza, Nectria berolinensis, Nectriopsis violacea, Neonectria ditis-
sima, N. fuckeliana, N. punicea. The first records in Slovakia hold for the species Nectria coryli,
Neonectria radicicola, Monographella nivalis, Paranectria oropensis, Pronectria pertusariicola,
Pseudonectria rousseliana and Sphaerostibella aureonitens. Nectria tuberculariformis, Nectriop-
sis indigens and Pronectria tincta can also be considered as very rare and, related to the record
date, also threatened of even extinct from the Slovak mycoflora.
