Anthracobia melaloma sur place à feu?
François Bartholomeeusen, 29-01-2014 14:34
Bonjour à tous,

C'est ma première participation au forum. J'ai peu d'expérience, à la fois en ce qui concerne les ascomycétes que la microscopie. Trouvé sur place à feu sur la rive d'un étang.


Description macroscopique: 1-4 mm, orange clair, en forme de disque, groupé au sol, sur la rive d'un étang. Sur le terrain, je n'ai pas trouvé des poils.


Description microscopie: matière fraîche dans l'eau.


Asques 8 sp, 166-178,41 x 10-11,86 µm.


Spores: biquittulées ; 16,89-20,43 x 7,74-9,27 µm; Q = 2.165


Paraphyse: cylindrique, septé et top gonflé, 163 x 4,5 (top: 6,46)µm


Poils: brun clair, septé, 89,97 x 4,56 µm


Lieu et date: Janvier 24, 2014 Belgique, Mol, de Maat; IFBL: C61434


Est ce que ça peut être Anthracobia melaloma? Je ne pouvais pas trouver de poils sur place. Avec le peu d'expérience que j'ai, je pense que le matériel a été endommagé, peut-être par le gel?


Quelle est votre opinion ?


Cordialement,


François


Hello all,


This is my first participation in the forum. I have little experience, both with respect to mushrooms as to microscopy. Fruiting body found on a fire place on the bank of a pond.


Macroscopic description: 1-4 mm, light orange, disc-shaped with ragged edge, in a group
on burnt ground between charcoal, on the bank of a pond. In the field, I was unable to find any hairs.


Place and date: January 24, 2014 Belgium, Mol Gauge;
IFBL: C61434


Could this be Anthracobia melalomae? On the spot, I was unable to find hairs. With the little experience I have, I suspect that the material was damaged, perhaps by frost?


What's your opinion?


Sincerely,


François

Hello, you write " no find hairs" but you have pics to show them ?  With such hairs melaloma seems right to me.

Hello Jean-Paul,

Thanks for your quick reply. What I meant was that I had not seen the hairs at the discovery place and with the  microscopy I was not sure if it was hair or hyphae, I do not have a good key.


greetings
François

Hi François


My picture shows the hairs of A. melaloma


You must try to do the mycroscopical preparations with the cleanest part of the ascomatal margin and flanks, and in KOH.

Hello Enrique,


Thanks for the tip. I have yet to learn how to handle tiny materials. My chemical stock consists exclusively of: eau de Javel, eau de toilette and eau de cologne.....
I'm just kidding, time to buy the right products.


Beautiful pictures, indeed, there was a lot of sand in my preparation,


kind regards
