Notes: Code: Bot_786/2014_DSC0137
Habitat: ruderal ground, wood edge near town outskirts, almost flat terrain, open and sunny place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 480 m (1.580 feet), alpine phytogeographical region.
Substratum: on bark of live Robinia pseudacacia branch.
Place: Bovec basin, north outskirts of Bovec, near ‘Žaršče’ place, East Julian Alps, Posočje, Slovenia EC
Comments: This small, orange, jelly blobs superficially appeared to me somewhat similar to Dacrymyces or Exidia species. But, very long and narrow, septated ‘spores’ and absence of fork like or longitudinally septated basidia, respectively, exclude these options. I was unable to find anything, which I could recognize as either basidia or asci. Hence I was speculating this observation could eventually be an anamorph of an ascomycete or a hyphomycete. Without experience with them I had no clue what it is. Also numerous sphaerocarps (see Figs. 5, 7, and 9) and large crystals in the context (Fig.:10) were (and still are) a secret to me.
Fortunately Mr. Neven Matočac (Ref.:1) was kind enough to teach me that determination to species level of such finds requires much more than pictures and a little bit of microscopy. In vivo studies, using cultures, and DNA analyses are in most cases required for any certainty level of determination. His very brief and tentative opinion was that the pictures probably show an anamorph of a member of Nectriaceae family, eventually from genera Haematonectria or Gibberella, while the macroconidia resembles to genus Fusarium.
Orange blobs were growing on and through the bark in an area of about 4 × 1 cm; SP was barely noticeable, probably whitish, but spores under the microscope were abundant.
