Durella melanochlora?
Jac Gelderblom, 11-02-2016 17:27

Sur bois de chêne j'ai trouve une petite discomycète (0,3-0,4 mm) quej'ai determinée comme Durella melanochlora.


Données: spores 12-14 x 4,5 micro; asques ca 40 x 11 micro.


               Parafyses avec exsudate brunatre.


Le spores ont une couleur gris-verdatre et ca me trouble parce que selon la litérature les spores seraient hyalines.


Qu'en pensez vous?


Amitiés

Re : Durella melanochlora?
D. melanochlora has hyaline spores. Did you test IKI? Perhaps a Dactylospora?

Re : Durella melanochlora?

Vielen Dank Hans-Otto für ihre Antwort.


Ich habe ein Preparat mit Iod gemacht und die ganze Asci haben sich gleich dunkelblau gefarbt.


Es betrifft hier also ein Dactylospora, jedenfalls ein Lichen.


Grüss


Jac Gelderblom

Re : Durella melanochlora?
Jawohl, sicherlich eine Dactylospora. Die lignicolen Arten sind schwer zu bestimmen oder teils sogar unbekannt.

Re : Durella melanochlora?
Hallo Jac,

The paper "Two New Species of Dactylospora (Dactylosporaceae, Lecanorales), with a Key to
the Known Species in Scandinavia" by Ihlen et al. (2004) includes a key to the lichenicolous species of the genus Dactylospora in Scandinavia. It may concern D. parasitica (with three septate spores) or a related species, which also seems to occur on wood (thus unlichenised). It has been found before in the Netherlands (see https://www.knnv.nl/sites/www.knnv.nl/files/2012%20Kaaistoepverslag%202011%2017e%20jaar_2.pdf , page 122).

Groeten, Eduard
