Lachnellula-occidentalis_26

Description:

Lachnellula occidentalis (G.G. Hahn & Ayers) Dharne, syn.: Dasyscyphus occidentalis G.G. Hahn & Ayers, Dasyscyphus willkommii var. hahnianus (Seaver) Robak, Lachnella hahniana Seaver, Lachnellula hahniana (Seaver) Dennis, Trichoscyphella hahniana (Seaver) MannerFamily: Hyaloscyphaceae EN: no name found, DE Gemeines Lrchen-Haarbecherchen, Lrchen-HaarbecherchenSlo.: mecesnova kosmievkaDat.: Dec. 27. 2019Lat.: 46.36030 Long.: 13.702342Code: Bot_1272/2019_DSC8863Habitat: abandoned pasture with some scattered trees and bushes; slightly inclined mountain slope, southeast aspect; calcareous, skeletal ground; sunny, relatively dry and warm place; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region.Substratum: thin, dead, fallen of branch of a Larix decidua tree; planted about 40 years ago.Place: Lower Trenta valley, between villages Soa and Trenta; right bank of river Soa, near the cottage Trenta 2b; East Julian Alps, Posoje, Slovenia EC. Comments: No microscopy has been done on these specimens, therefore the determination is not reliable. There exist several similar species of the genus Lachnellula. This find can easily be very similar Lachnellula willkommii. Both species (some people suspect that both are actually the same species) are widespread and among the most common in the genus.The pictures show the fungi in a relatively dry state. Therefore, the fruit bodies look mainly as a small, white, wooly tufts. In humid conditions they 'open' and show their bright yellow-orange hymenium. Also it appears that not all fruit bodies are fully developed. May be due to quite cold weather at the time of observation, although Lachnellula species are known to be fairly resistant to cold and dryness.
