When: 2013-04-01
(46.2919° 13.5102° 360m)
No herbarium specimen

Notes: Auricularia auricula-judaea, syn: A. auricula, A. auricularis, A. sambuci
Jelly Ear
Slo.: bezgova uhljevka, judeževo uho

Dat.: April 01. 2013
Lat.: Long.:
Code: Bot_692/2013_IMG2541

Habitat: Steep river bank, northeast oriented, calcareous ground, in mixed predominantly Fagus sylvatica forest, humid place (ground and air), about 15 m above water level of the river, mostly in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 360 m (1.200 feet), alpine phytogeographical region.

Substratum: a large stump of a cut down Fagus sylvatica in its initial stage of disintegration.

Place: Soča valley between Kobarid and village Žaga, left bank of river Soča near village Srpenica, East Julian Alps, Posočje, Slovenia EC.

Comments: Unusual shape and substratum. Short but distinctive stalk. First I thought it’s an ascomycete like Peziza sp. or something similar. But I found no asci. Growing solitary, pileus diameter 2.5 cm (~1 inch), flesh gelatinous, almost liquid, with quite strong, flexible and thin ‘skin’, hairy underside; SP faint whitish. During drying it shrunk heavily.
