Mushroom Observer Image 640160: Lasiobelonium relicinum (Fr.) Raitv.

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. Dimensions: (16.4) 17.8 - 21.8 (24.6) x (4.8) 6 - 7.9 (9.1) microns, Q = (2.2) 2.4 - 3.4 (3.7) ; N = 31; Me = 20 x 7 microns ; Qe = 2.9.

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. All observed fruitbodies, except one (Figs. 9. and 10.), seem to grow on normal not deformed branches. - Spores smooth. Dimensions: (16.4) 17.8 - 21.8 (24.6) x (4.8) 6 - 7.9 (9.1) microns, Q = (2.2) 2.4 - 3.4 (3.7) ; N = 31; Me = 20 x 7 microns ; Qe = 2.9.
