Observation 154168: Lachnellula splendens (J. Schröt.) Baral & Matheis

Lachnellula splendens
Slo.: ?

Dat.: Nov. 10. 2013
Lat.: Long.:
Code: Bot_771/2013_DSC9185

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.

Place: Lower Trenta valley, near ‘Na Melu’ place, between villages Soča and Trenta, East Julian Alps, Posočje, Slovenia EC

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 it is 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) micr., n = 6.

Sequencing is still a problem

Sequencing is still a problem in my country. I was modestly involved into studies of Nigritella species in Slovenia. A new species was (allegedly) discovered in Slovenia recently http://www.flickr.com/... , however, not all pros agreed with it. Now it is the third year we are talking about sequencing of all Slovenian Nigritellas, because there is a lot of ambiguity with them. Morphological differences are very ‘tiny’ and very variable at the same time. But somehow still nothing has happened so far… Frankly, I don’t know where is the problem, is it high cost or lack of knowledge. May be that the botany is financially so underfeed here? Lucky you …. Meanwhile, if Nigritella species from Alps are in the Genbank coded by the names only, then they have a real problem. Thank you Martin for your suggestion about picture captions. I will try to use them more frequently.

Ahh haaa!

I thought that microscopy was too good to be true. But I really like it, and will try it myself soon. You should add a short descriptive label underneath the photos so it is easier to tell them apart. My own personal project is to sequence a whole bunch of local species, post the material to Genbank, and add the link to the MO Observation. It is fairly pathetic that the main repository for genetic data does not require morphological data or a picture of any kind. So on this continent where people on both coasts use the same name for a different critter, (and everyone knows it) and the name is borrowed from Europe anyway, the idea that you can compare different sequences by using the name as a contact point is silly, pathetic, or to put it nicer, just a starting point! But it seems like a starting point that could already benefit from some revision in thinking.

Hi Martin,
Thank you for your comment and praise. Regarding sequencing data I asked Slovenian Forestry Institute whether they have interest to make the analysis. Unfortunately, they are not since their main research interests (for which they are paid) are pathogens potentially important for forests. However, they confirmed my determination and told me that this observation is a new species in Slovenia. So, I will start the process to register it. Of cause I have to present the herbarium sample to Slovenian Mycological Commission for inspection, but after that, if you know somebody, who would like to make sequencing, I am just happy. I’ve never have a contact with people, who do this job.
The picture of spores and the picture with three asci and two paraphyses are arranged. The picture of aski is a combo of two shots (a simple PhotoShop copy/paste, rotate, merge layers). The picture of spores is a combo of several shots (may be up to ten) processed in the same way. Nevertheless, spores were quite abundant.

amadej does it again.

these are, hands down, the finest observations on the site.

Fantastic observation!

Great job amadej! The only thing missing is a link to sequence data on another site, preferably for me on GenBank, but European based site also fine. Any chance that will be added? Currently there is none. It would be excellent for this observation to be the first.


Did you arrange photo 11? It looks too good to be true.
