location
Lower Trenta valley, left bank of river Soča, between villages Trenta at Soča, across the river near Soča 46 house, East Julian Alps (Posočje, Slovenia)notes Slo.: trobljasta rebrica - Habitat: at the foot of a mountain, river bank, modestly NW inclined slope, mixed wood on scree, rocks and boulders, in shade, humid place in shade of a mountain, almost no sun, calcareous ground, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 525 m (1.720 feet), alpine phytogeographical region. - Substratum: fallen, dead, mostly debarked Fagus sylvatica trunk (diameter about 25 cm) in its late initial stage of disintegration. - Comments: Growing in groups, many fruit bodies; pileus diameter up to 7-8 mm, about 6 mm high at max; taste and smell indistinctive; flesh gelatinous but quite firm; SP yellow, oac 856. Spores have been observed twice with quite different results. On the day of observation spores were collected with a soft wet brush directly from the largest fruit body. These spores had no septa. Two days after spore print was analyzed.These spores were mostly three septated as expected and significantly larger. On many germinating spores small spherical conidia can be seen. - This is a widespread species but in literature mostly considered as a rare one. In Britain and Ireland it is very seldom recorded (Ref.: (4)) while Ref.: (5) considers it as rare worldwide.The Bovec region seems to be an exception, because this observation is my fifth here around. - Spores smooth. Dimensions when collected by rubbing fertile surface of the largest, apparently mature fruit body by a soft wet brush: 13.5 (SD = 1.0) x 5.1 (SD = 0.4) μ, Q = 2.7 (SD = 0.23), n = 30. Spores taken from spore print two days later: 14.2 (SD = 1.1) x 6.0 (SD = 0.2) μ, Q = 2.37 (SD = 0.2), n = 28.Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil, (and NEA 40x/0.65, magnification 400x other pictures), in water.
