INFORMATION PROVIDED WITH THE PHOTO
  • date of photo  Sep 19, 2009
  • latitude 46.37473   longitude 13.74063     View on Google Maps.
  • location   Lower Trenta valley, left bank of river Soča, southwest of village Trenta, downstream of Matoja Inn, East Julian Alps (Posočje, Slovenia)
  • notes   Slo.: bakreni polžar - syn.: Gomphidius viscidus (L.) Fr. - Habitat: sandy grassland; mixed broadleaved and conifer wood edge; Picea abies, Pinus sylvestris, Salix eleagnos in the vicinity; semiruderal, calcareous ground; flat terrain; dry, half sunny place; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 580 m (1.900 feet), alpine phytogeographical region. Substratum: soil. Comments: Croomogomphus rutilus is a quite common fungus in this region. Two other species Chroomogomhus helveticus and C. glutinosus grow in the same region. It is not always simple to tell them apart. C. glutinosus is normally very slimy and grows always under Picea abies while Croomogomphus rutilus grows only under two-needle pines. C. helveticus is rarely slimy but grows under Picea abies, two- and fife-needle Pinus species. Inamyloid hypha of the pileipellis is another more demanding distinguishing character. Spore dimensions are very similar of all three and hence of little help in discrimination. Different mycorrhizal partners also did not help in identification of this find since Picea abies and Pinus sylvestris (a two-needle species) were in the vicinity. Yet, characteristic copper tone of the pilei seems to be quite a reliable feature for Croomogomphus rutilus. Growing in small groups of a few fruit bodies and solitary; SP abundant, grayish-brown. Spores smooth. Dimensions 17,3 [18,5 ; 19,1] 20,3 x 5,8 [6,4 ; 6,6] 7,1 microns; Q = 2,6 [2,8 ; 3] 3,2; N = 24; C = 95%; Me = 18,8 x 6,5 microns; Qe = 2,9.
