Observation 191407: Ramaria aurea (Schaeff.) Quél.
When: 2014-10-02
(46.3596° 13.7585° 1200m)

Notes: Code: Bot_836/2014_DSC4052

Habitat: old mixed wood, dominant Fagus sylvatica mixed with Abies alba and Picea abies; locally almost flat terrain, calcareous ground, in shade, relatively cold and humid place, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 3-5 deg C, elevation 1.200 m (3.900 feet), alpine phytogeographical region.

Substratum: leaf litter and soil under a Fagus sylvatica.

Place: Lower Trenta valley, former Planina Lepoč, next to the trail from Trenta village to Prehodavci pass, northwest slopes of Mt. Lepo Špičje ridge, East Julian Alps, Posočje, Slovenia EC.

Comments: Microscopy revealed simple hypha septa and very wide spores for Ramaria genus. This fits well to Ramaria aurea. Also vividly yellow upper part of the stump (see Fig.5. and the key in Schild’s paper, Ref.: 3) and quite good fit of measured spore dimensions to Schild’s data speak for Ramaria aurea. Spores are still a little bit too wide. They would fit even better to similar Ramaria largenti (having spores dimensions 10-16/4-6.5 microns according to Schild) but this species thrives in coniferous forests, while this find grew under Fagus sylvatica. Also Ramaria largenti is more orange. So Ramaria aurea seems to be the best fit.

Growing in a group of four sporocarps within a range of approximately three by one meter; fruit bodies up to 14 cm tall and 9-15 cm wide; stump massive, up to 4-5 cm tall and 4 cm in diameter; branches fragile; no discoloring noticed when injured, cut or bruised; SP very faint, color could not be determined.
