location
Vrsnik valley, below 'Na skali' settlement, above Pod Vršičem place, East Julian Alps (Posočje, Slovenia)notes Slo.: črneča ožganka - syn.: Ustulina deusta (Hoffm.) Lind, Hypoxylon deustum - Habitat: light, mixed woodland Picea abies and Fagus sylvatica dominant; slightly inclined mountain slope, south aspect; calcareous, skeletal ground; half shade, quite humid place; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 6 - 8 deg C, elevation 715 m (2.350 feet), alpine phytogeographical region. Substratum: mostly debarked places of a heavily decayed, still standing trunk of Fagus sylvatica. Comments: This is a quite a common fungus in Upper Posočje region, not really among the most beautiful, but still interesting. This species is much brighter when young, becoming black as charcoal when old. Growing on several places of a still standing trunk of large Fagus sylvatica. Ascomata confluent into patches up to 25 x 10 cm, with bumps from 3 to 10(15) mm in diameter, 2 to 6(10) mm thick, perithecia about 1 mm in diameter; very brittle, so it can't be cut even not with a sharp surgical knife without breaking it into pieces; no smell; SP none, spores found within crashed perithecia; these were rather old sporocarps. Spores smooth, dark, seems much flattened on one side (which probably explains large variability of their measured width compared to stable length), some with small drops. Dimensions: 28.3 [30.3 ; 31.2] 33.1 x 8.8 [9.9 ; 10.5] 11.6 microns; Q = 2.5 [2.9 ; 3.1] 3.5; N = 30; C = 95%; Me = 30.7 x 10.2 microns; Qe = 3.
