Notes: Code: Bot_835/2014_DSC3951
Habitat: mixed wood, Picea abies and Fagus sylvatica dominant, moderately steep, southeast oriented mountain slope, calcareous skeletal ground covered by leaf and needles litter without ground vegetation, under Picea abies, in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, elevation 950 m (3.100 feet), alpine phytogeographical region.
Substratum: on moss covering a small Picea abies stump in the last disintegration stage, decomposed to almost soil.
Place: Lower Trenta valley, near the trail from Trenta village to Zasavska koča na Prehodavcih mountain cottage, halfway between the village and Planina Lepoč, East Julian Alps, Posočje, Slovenia EC
Comments: Geastrum quadrifidum is among the smallest species of about 50 of them worldwide (and ten of them described in Slovenian checklist (Ref.7)). It is a rare find. As its species name suggests it usually has four exoperidium ‘legs’. However, sometimes, as in my find, it has five of them. Growing solitary; exoperidium diameter 20 mm, endoperidium diameter 8 mm, its height (without the peristom ‘beak’) 7 mm; SP and spores on mass dark brown.
