Abstract

Psathyrella ammophila is a psammophilous fungus most frequently inhabiting seashore beaches, sand dunes and sandy inland areas. Although it is a widely spread species, in some countries it is rare or threatened, including Poland, where it is classified as “endangered” (E). In Poland, P. ammophila has been found in 26 localities, including 14 new reports after 1970. We present two new Polish localities from white sand dunes at the western shore of the Baltic Sea (Wolin Island). Moreover, ecological information and macroscopic and microscopic features of the basidiocarp based on collected samples are presented. The problem of the disappearance of dunes as a primary habitat of P. ammophila is also discussed.

Highlights

Climatic changes, which result in the elevation of the sea and ocean levels as well as more aggressive abrasion of seashores (Jakusik et al, 2012; Prasad & Kumar, 2014; Räisänen, 2017) lead to, among other consequences, degradation and disappearance of habitats such as mobile white or grey dunes (e.g., NamuraOchalska, 2004a, 2004b; Tylkowski, 2017)
Considering the modest biological variability of seashore dunes, even a minimal disturbance in their biological balance may be dangerous to the survival of species strongly dependent on this habitat. This especially refers to a small group of dune-inhabiting macrofungi, including Hohenbuehelia culmicola Bon, Laccaria maritima (Theodor.) Singer ex Huhtinen, Phallus hadriani Vent., and Psathyrella ammophila (Durieu & Lév.) P
The fungi are vulnerable because of their specific requirements of sandy nutrient-poor sites with initial vegetation (Fraiture & Otto, 2015). This type of vegetation is rare in Europe and mainly threatened by coastal management and by nitrogen deposition from air pollution (Houston, 2016; Ozinga et al, 2013)
