Nectriopsis lecanodes

Gernot Friebes, 02-12-2011 20:56

Hi,

I am looking for the part of the following article that deals with Nectriopsis lecanodes:

Sérusiaux, E.; Diederich, P.; Brand, A.M.; Boom, P. 1999 - New or interesting lichens and lichenicolous fungi from Belgium and Luxembourg. VIII. Lejeunia 162: 1-95.

It'd be great if somebody could send me these pages.

Best wishes,

Gernot

Re : Nectriopsis lecanodes

Hi Gernot,
I haven't those pages but I know this species quite well (Christian too). If you want confirmation, please give your observations.

Re : Nectriopsis lecanodes

Tu le trouves sur quel support toi Alain ?

Re : Nectriopsis lecanodes

Je le trouve sur Peltigera leucophlebia mais il est donné aussi sur Parmeliella, Peltigera, Lobaria, Nephroma et Pseudocyphellaria. Donc principalement des Peltigerales.

Re : Nectriopsis lecanodes

Hi Alain,

thanks but I'm not actually looking for confirmation but for a recent description with synonyms and maybe further literatur given for this species. Also I'm not sure if the correct basionym is Sphaeria lecanodes Ces. 1857 or Nectria lecanodes Ces. 1863...

Best wishes,

Gernot

Re : Nectriopsis lecanodes

Dear Gernot,
here is the basionyme of N. lecanodes:

Nectriopsis lecanodes (Ces.) Diederich & Schroers
Basionym: Nectria lecanodes Ces., in Rabenhorst, Herb. mycol. ed. 2: 525, 1863.

However, ?I think that it is not the genus Nectriopsis but the genus Lasionectria, I'm working to a new combination. In section, ascomatal wall >40 µm thick composed of two regions fits better to the genus Lasionectria

Best wishes

Christian

Re : Nectriopsis lecanodes

Hi Gernot.
I can get these pages, but only on the next Monday.

Gernot Friebes, 03-12-2011 12:56

Re : Nectriopsis lecanodes

Hi,

@Christian: Thanks for this information! I thought there already was a combination to the genus Lasionectria? (http://www.cybertruffle.org.uk/cyberliber/59351/0021/003/0267.htm)

@Nicolas: That would be great, thank you!

Best wishes,

Gernot

Re : Nectriopsis lecanodes

thank you very much, Nicolas! I'm a bit surprised by the different descriptions in literature concerning the ascospore ornamentation: "distinctly verruculose to verrucose" in Sérusiaux et al., "finely punctate" in Dennis (British Ascomycetes) and "smooth" in Nordic Macromycetes Vol. 1. I observed the ascospores to be finely punctate but with the tiny warts arranged longitudinally so the ascospore surface seemed somewhat striate (I add micros). What is your experience with this species?

Best wishes,

Gernot

Alain GARDIENNET, 06-12-2011 22:15

Re : Nectriopsis lecanodes

Exactly the same observation about spore's ornementation : finely and longitudinally warted, almost striated.
But, it's obviously 'Nectriopsis' lecanodes.

Re : Nectriopsis lecanodes

Hi Alain,

thanks for sharing your experience! Maybe the different descriptions result from different maturities of the material examined in literature.

Best wishes,

Gernot
