Buenas nochesTengo varias recolecciones de Lachnum virgineum (http://www.micobotanicajaen.com/Revista/Articulos/Fichas/Fichas008/LachnumVirgineum.htm), pero en esta ocasión la microscopía es algo distinta, sobre todo en cuanto a las puntas de los pelos, que son bastante engrosados, y he pensado que podría tratarse de Lachnum subvirgineum. Recolectado en Tenerife (Islas Canarias) en bosque "Monteverde": laurel (Laurus novocanariensis)y brezo (Erica arborea). Ver pdf adjunto.
Gracias,

Good night
I have several records of Lachnum virgineum (http://www.micobotanicajaen.com/Revista/Articulos/Fichas/Fichas008/LachnumVirgineum.htm), but this one has a little different microscopial characters, because it has a clavate tips hairs. I think it could be Lachnum subvirgineum. Record from Tenerife (Canary Islands), in "Monteverde" forest: laurel (Laurus novocanariensis) and brezo (Erica arborea). See attached pdf file.
Thank you,

Re:Lachnum subvirgineum
Dear Miguel
yes, I believe this is L. subvirgineum. Why do you write that croziers are also absent? I see very well the croziers in most of your images. The hairs are also shorter in L: subvirgineum compared to L. virgineum. Do you have no possibility to study your specimens when fresh? The micros are all in dead state, and therefore you loose the VBs which are characteristic of quite a lot of Lachnum species.

Re:Lachnum subvirgineum
Dear Zotto, thank you very much.
Sorry, but, where have you read that "croziers are also absent"? At the second photo in the attached pdf I say "with croziers (right)". I can't find that text.
I used to stay at Tenerife during a week-nine days in June and another week-nine days in December, and I try to come back with a lot of fresh material, but the first days material is difficult to mantein in good condition. Another times I bring the funghi in fresh conditions but I have no time to process all of fresh material, like this L. subvirgineum, because I though it would be L. virgineum again, so perhaps I took more attention to other species before this. Sorry.
Thank you again

Re:Lachnum subvirgineum
Dear Miguel
sorry, I must have been overworked yesterday. Now everything is o.k. :-)
I understand of course the problem with fresh specimens from far away. When I see the fresh macro I think why is the micro so dead. But now I see there are some weeks between. My collections from Tenerife from about 1978 are largely still unexamined :-(
