Totally unfamiliar

March 17, 2007, Naro-Fominsk, Moscow region, at the base of a dry stem of herbaceous plant (most probably Urtica). Hight up to 1.5-2 mm. I don't think it's a right place to ask but maybe someone could recognize it... My guess it's a slime mold.

Re:Totally unfamiliar

I couldn't make out much with the microscope. Its base seems to be covered with fine hairs. I could also see some root-like structures. Here's a portion of its external structure.

Re:Totally unfamiliar

Hi,

I have no idea. But the outside structure reminds me of the structure of several sclerotia, e.g. from Typhula or from some Sclerotiniaceae. May be it something in this direction?

best regards,
Andreas

Re:Totally unfamiliar

Hello Andreas,

Thanks for the hint. Sclerotia might be a good idea. I am only familiar with more or less spherical yellowish to brown sclerotia which were abundant on fallen leaves in humid places from autumn throughout this (exceptionally mild) winter.

Re:Totally unfamiliar

Hi Dmitry

probably you are writing about this Sclerotia of Typhula: http://www.bio-forum.pl/messages/33/10209.html

Re:Totally unfamiliar

I've found quite similar images of Typhula quisquiliaris at http://www.mykonet.ch/Pilzbilder_T.htm, http://www.mycocondroz.be/champignons/t/typhula_quisquillaris.jpg and http://karlkeck.heim.at/typhquis.jpg. T. sclerotoides at http://www.nahuby.sk/sk/sources/obrazok_detail.php?id=2241 also looks alike. T. uncialis at http://www.floraislands.is/fungpic.htm seems less fit. Is it possible to grow basidiocarps from them?

P.S. Thanks Piotr - the initial pix do look quite similar.
P.P.S. According to the key for European Clavariaceae (Pilat, 1958), Typhula quisquiliaris occurs on Pteridium aquilinum which is not the case...
