Descrission:

Fungi Bartl. ? (sp.1) - Hanitat: Steep mountain slope NNW oriented, mixed forest, Picea abies and Fagus sylvatica dominant; calcareous bedrock, however acid local ground possible, next to the mountain trail, in full shade, humid place, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 3-5 deg C, elevation 890 m (2.900 feet), alpine phytogeographical region. Substratum: forest ground, rotten leaf and needles litter. - Comments: No idea what could this pale blue quite dense fibrous saliva be? Any help appreciated! It looked neither like a myxomicete nor like excrement. Possibly non-fungal. A kind of algae? To some extent similar to Trentepohlia aurea (except color, of course)? A few patches in the radius of half a meter (1.5 feet) found.
