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. Ref.: (1)

Habitat: alpine valley, mixed forest edge, dominant Fagus sylvatica, Picea abies, Ostrya carprinifolia, Fraxinus ornus, Fraxinus excelsior, Corylus avellana, modestly southeast inclined mountain slope, calcareous ground (overgrown old scree, rock and boulders), limestone bedrock, relatively dry and warm place, partly sunny, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.950 feet), alpine phytogeographical region. - Substratum: dead, thin, very small piece of Picea abies branch loosely lying on rocky ground. - Comments: This seems to be a rare observation. There are more than 30 species in Genus Lachnellula, which are not easy to determine to species level. By luck L. splendens has unique spores, so I hope my determination is correct. Lachnellulas seem to be associated with Larix decidua canker and therefore an economically important genus. - Growing in a group of four fruit bodies on a single small branch. I have been trying hard to find some more fruit bodies, but with no success. Pileus diameter 1.2 (SD = 0.3) mm, n = 4, hairs length: 117 (SD = 23) μ, n = 6. - Spores smooth with many small oil drops.

Habitat: alpine valley, mixed forest edge, dominant Fagus sylvatica, Picea abies, Ostrya carprinifolia, Larix decidua, Fraxinus ornus, Fraxinus excelsior, Corylus avellana; modestly southeast inclined mountain slope, calcareous ground (overgrown old scree, rocks and boulders), limestone bedrock, relatively dry and warm place, partly sunny, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.950 feet), alpine phytogeographical region. - Substratum: dead, thin branches of Larix decidua still attached to the tree. - Comments: Several fruit bodies on several branches were found. The determination seems to me quite certain in spite of the fact that there exists many species in genus. L. occidentalis has relatively large spores, which, together with the substratum, much reduces number of options. The only eventual alternative seems to be Lachnellula willcommii. However it has broader spores (8-10 microns) and it is usually associated with Larix decidua cankers.

Habitat: alpine valley, mixed forest edge, dominant Fagus sylvatica, Picea abies, Ostrya carprinifolia, Larix decidua, Fraxinus ornus, Fraxinus excelsior, Corylus avellana; modestly southeast inclined mountain slope, calcareous ground (overgrown old scree, rocks and boulders), limestone bedrock, relatively dry and warm place, partly sunny, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.950 feet), alpine phytogeographical region. - Substratum: dead, thin branches of Larix decidua still attached to the tree. - Comments: Several fruit bodies on several branches were found. The determination seems to me quite certain in spite of the fact that there exists many species in genus. L. occidentalis has relatively large spores, which, together with the substratum, much reduces number of options. The only eventual alternative seems to be Lachnellula willcommii. However it has broader spores (8-10 microns) and it is usually associated with Larix decidua cankers. All observed fruitbodies, except one (Figs. 9. and 10.), seem to grow on normal not deformed branches. - Spores smooth.
