INFORMATION PROVIDED WITH THE PHOTO
  • date of photo  Jul 31, 2011
  • latitude 46.29742   longitude 13.46668     View on Google Maps.
  • location   Northeast slopes of Mt. Kobariški Stol mountain ridge, near the top of Prvi Hum hill southwest of village Žaga, East Julian Alps (Posočje, Slovenia)
  • notes   Slo.: zelenkasti zelenivec - syn.: Chlorosplenium aeruginascens (Nyl.) P. Karst., Peziza aeruginascens Nyl. - Habitat: Fagus sylvatica forest with some Picea abies; moderately steep mountain slope, north aspect, calcareous ground, in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, elevation 1.000 m (3.300 feet), alpine phytogeographical region. Substratum: a highly rotten trunk of probably Fagus sylvatica lying on ground. Comments: Chlorociboria aeruginascens is a small but stunning colored fungus. It stains decaying wood beautifully blue-green by the production of the pigment xylindein. The stained wood has been used by woodworkers for centuries to provide the blue-green colors in their marvelous inlaid intarsia designs (see Ref.1). Two morphologically indistinguishably similar species of Chlorociboria exist: Chlorociboria aeruginascens and Chlorociboria aeruginosa. They can be distinguished only microscopically, mainly by the size of their ascospores. The spores of Chlorociboria aeruginosa are typically larger than those of C. aeruginascens. Unfortunately, I found no spores and hence it is not sure, which species the pictures show. Since the Chlorociboria aeruginosa is much less frequent in general and also in Slovenia I assume I photographed Chlorociboria aeruginascens. These two fungi are distributed throughout the temperate forests of the world. Ref.: (1) http://botit.botany.wisc.edu/toms_fungi/jul2008.html (2) M.Bon, Pareys Buch der Pilze, Kosmos (2005), p 332.
