Arachnomyces and Literature search
Norbert Heine, 21-01-2012 14:32
Norbert HeineBonjour à tous, Hi to all,

I'm looking for a copy of the Malloch & Cain paper: The genus Arachnomyces
Canadian Journal of Botany, 1970, 48:(5) 839-845, 10.1139/b70-115
Also I'm interested in: Singh & Mukerji: Studies on Indian coprophilous fungi. III.
The genus Arachnomyces.-Indian.J.Mycol.Res. 16 (1978): 283-289


Actuelly I have on sheep dung Arachnomyces sulphureus Massee & E.S. Salmon (1902) or Arachnomyces nitidus Massee & E.S. Salmon (1902). I'm not sure. Does anybody of you know this small ascomycet?


Perithecia: 300 - 600 µm, yellowish-brown, few together, with red-brown appendages (2-5 mm long, spirally contorted at the apex)
Ascospores: orbicular, if seen from the front and broadly elliptical from the side
3,5-5 x 3,5-5 x 2,5-3 µm, pale brown in mass
Asci: numerous, 8-10(11) µm


Best regards and thanks for your help
Norbert

Re : Arachnomyces and Literature search
Dear Norbert,

I do not read AscoFrance every day and have just seen your request for our paper on Arachnomyces.  It is attached here.  Your picture looks like A. nitidus.  It does not seem to have the sulfur yellow covering of the cleistothecia that we see in A. sulphureus.  If you have the materials for culturing, it should grow and fruit very well.

Re : Arachnomyces and Literature search
Dear Dave,
nice to see you here and thank you very much for your comment.
Meanwhile I've got the paper and I could determinate this Arachnomyces as A. nitidus.
You're right there is no sulfur yellow covering of the cleistothecia.
Maybe this is the first find in Germany.
Do you know something about the distribution in Europe?
Kind regards
Norbert
PS. By the way, your attached link does not work.

Re : Arachnomyces and Literature search
Dear Norbert,

Reports of Arachnomyces species seem to be quite rare.  Checking through culture collections I find only one strain of A. nitidus from Israel.  Your German record must be a first.

I do not understand why my upload of the Arachnomyces paper didn't work.  I tried a second time and that too doesn't work.  Fortunately you have your own copy now.

Kind regards,

Dave

Re : Arachnomyces and Literature search
Dear Dave & Norbert,

my first message was swallowed up in cyberspace, I'm afraid. Anyway, a collection of A. nitidus in Spain has been described by M. Valldosera & J. Guarro in Revista Iberica de Micologia 1(1), 1984.

@ Norbert: Ich kann Dir jederzeit eine Fotokopie schicken, aber die "Scanner" erledigen sowas ja meist viel schneller.


Regards/Gruß
Till

Re : Arachnomyces and Literature search
Thanks Dave, for your further answer. It's interesting for me to know.

@Till: Ich würde mich freuen, wenn Du mir den Artikel, in welcher Form auch immer, schicken könntest. Den suche ich schon länger.

Kind regards
Norbert
