Habitat and geographical distribution.

Saprobe on decaying deciduous wood of Acer campestre , Alnus glutinosa , Quercus sp. and other unidentified hosts, and on decaying basidioma of Trametes gibbosa , known from the Czech Republic, Belgium and France ( Réblová 2006; MyCoPortal; this study). According to GlobalFungi, identical sequences were found in 50 samples collected in temperate and subtropical regions. These samples mainly originated from air, soil, but also shoots, roots and deadwood. Ceratostomella pyrenaica is commonly found in croplands and forests, also in grasslands, woodlands and anthropogenic habitats in Croatia, Czech Republic, Italy and the USA (Hawaii, Michigan, and North Carolina).

Notes.

Ceratostomella pyrenaica is well distinguished from other species by its ellipsoidal to oblong ascospores, which are slightly curved, apiculate at both ends and flattened on one side, pale brown, measuring 7–9 × 3–4 μm.
