When: 2014-02-25
(46.3611° 13.7025° 615m)

Notes: Code: Bot_785/2014_DSC0119

Habitat: Light mixed wood edge, Fagus sylvatica, Picea abies, Ostrya carprinifolia, Fraxinus ornus, Corylus avellana dominant; modestly southeast inclined terrain; calcareous ground, overgrown old scree and rocks; relatively dry and warm place; mostly in shade; partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 615 m (2.000 feet), alpine phytogeographical region.

Substratum: still standing dry branch of Corylus avellana still in bark and about 3.5 cm in diameter; sporocarp about 1 m (3 feet) above ground.

Place: Lower Trenta valley, east of ‘Na melu’ place, between villages Soča and Trenta, East Julian Alps, Posočje, Slovenia EC

Comments: This quite rare Polyporaceae was growing solitary in a form of three ‘pilei-like’ clumps fused together, all three together measured 6 × 2.5 cm and were max 1 cm thick; flesh hard, brittle, fibrous; sporocarps photographed in still moist, apparently alive condition; but SP none – I have no good luck regarding spores with this species.
