Observation 161598: Cladonia gracilis (L.) Willd.
When: 2013-09-06
(46.3609° 13.7036° 590m)

Notes: Code: Bot_748/2013_DSC7921

Habitat: abandoned stony pasture, moderately southeast inclined mountain slope with some Picea abies and Corylus avellana bushes, overgrown calcareous, stony ground, however possibly somewhat acid; very shallow soil layer, more or less open place, but mostly in shade of high Picea abies trees,exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevations 590 m (1.950 feet), alpine phytogeographical region.

Substratum: stony ground, among low grasses and mosses.

Place: Lower Trenta valley, between villages Soča and Trenta, former pasture near abandoned farm house ‘Koc’, Trenta 3, East Julian Alps, Posočje, Slovenia EC

Comment: Determined by habitus and habitat only. No chemistry tests done. This species is very variable according to literature. Usually published pictures show much less podetia squamules and less branched habitus. Hence I have doubts the determination is correct. On other side. Ref.:(1) shows very similar habitus. Also I was unable to find a better alternative with characteristically almost absent ground squamules and typical ‘cups’ of the podetia.
