Habitat: Roadside of a dirt forest road surrounded by almost pure Fagus sylvatica forest, NW faced steep mountain slope, calcareous bedrock, quite humid and shady place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 655 m (2.150 feet), alpine phytogeographical region.
Substratum: almost completely decomposed trunk of a deciduous tree lying on ground in abundant ground vegetation and bushes; almost certainly not a conifer, most probably Fagus sylvatica.
Place: Bovec basin, NW slopes of Javoršček Mountain, 1.557 m (5.109 feet), toward the end of forest dirty road, East Julian Alps, Posočje, Slovenia EC
Comments: Growing in several clusters on a decomposed log. The size of the largest clumps was about 2.5 × 1.5 cm (1 × 0.7 inch). Photographs have been made on three different days, one and five days after the first visit.
Macro and micro characters fit well to Tubiferra ferruginosa, which is a common slime mold. However I am wandering about the picture No.12. One can see a pseudoaethalia in a quite decomposed state where many of individual sporangia have a small pink bump in the center, which looks like a pseudocapillitium, which takes the form of a columnella-like central body. If my assumption is correct then this character may eventually testify for a Tubireffa casparyi, which is much less common than T. ferruginosa. Unfortunately, I was unable to find additional information about this species or some additional information whether such a central body can be seen also on Tubiferra ferruginosa. A second ‘problem’ is the log. According to Ref. (2) T. ferruginosa substrate are confers and rarely alder or birch. It is almost certain that the log in my case was none of these. There are no alders or birches around and its appearance, though almost nearly totally decomposed, didn’t look like a conifer. Any expert opinion would be appreciated very much.
