Phellinus hippophaëicola (Hymenochaetaceae) Is Not Rare in Poland: Findings from the Pobrzeże Szczecińskie Coastland

Abstract

The occurrence of Phellinus hippophaëicola H. Jahn, a fungal pathogen of Hippophaë rhamnoides L., on the Pobrzeże Szczecińskie coastland, NW Poland, was surveyed during 2015–2016. Altogether 59 localities of Phellinus hippophaëicola were recorded, including the first Polish inland locatlities on cultivated plants of Hippophaë rhamnoides. The localities are from 18 ATPOL grid squares, including 43 localities on the Baltic Sea coast. Phellinus hippophaëicola occurred at 74% of all the localities of Hippophaë rhamnoides examined, and at ca 84% of the plant’s natural sites. These findings, and also the status of Hippophaë rhamnoides as a protected species occurring in protected habitats in Natura 2000 sites, mean that Phellinus hippophaëicola is not a rare and endangered species in Poland. In total, 69 localities located in 28 ATPOL grid squares, including the localities reported here, are currently known from Poland.
