    Dear Norbert!

    I read with a great interest the discussions devoted to "Sordaria minima Sacc. & Speg." and Melanospora aculeata E. C. Hansen: on this site as well as on Ascofrance.

    Fruit bodies of our samples lack seta. We also found Thelebolus cf. stercoreus near the one of perithecium.

    All features we observed fit those in descriptions of "Sordaria minima" collections from the UK (Massee & Salmon, 1901; Richardson, 1998), Denmark (Larsen, 1971), and Italy (Doveri, 2004).

    Dear friends.

    Thanks for answers.

    I agree with the Rada. Massee & Salmon (1901) and Richardson (1998, 2004) admit that due to small perithecia it can be also overlooked.

    In one of our specimens, an apothecium of Thelebolus cf. stercoreus was also found in immediate proximity to perithecia of S. minima.

    I agree with the Nobi too. Nomenclature, identity and placement of this taxon remain problematic. It is referred to in the literature as “Sordaria minima problem” (Doveri, 2004). We use the name S. minima Sacc. & Speg. because it is currently listed as accepted name both in Index Fungorum and Mycobank .

    Dear friends.

    We are now preparing to print an article about new and noteworthy records of coprophilous ascomycetes from Ukraine. Among them is «Sordaria minima».

    Sordaria minima Sacc. & Speg., Michelia 1(4): 373. 1878. This is a very interesting and rare fungus. We assume that this is a new record for Eastern Europe. The question is about its distribution. From the available sources we know about the following localities: Denmark, Germany (Am I right?), Iceland, Italy, Netherlands, Sweden, UK, USA, Argentina.

    Please specify! Perhaps we missed something?

    Thank you.

    Dear Michael!

    I speak both Russian and Ukrainian. :)

    I try to teach my students how to collect mushrooms at least. But it does not always work. The traditions of collecting Paxillus involutus in Ukraine and Russia are very strong. In my childhood I often collected it myself. He, by the way, is quite tasty. ;) It's hard to find arguments when they say to you: "I've eaten it all my life!".

    Dear Nobi!

    Thanks for your welcome. Also thank you very much for the qualified answer and appreciation of my photos!

    Regarding questions about me and about the sample that I collected.

    I’m mycologist, a university lecturer from Ukraine. In recent years, my research interests include coprophilous ascomycetes. I have been studying their species diversity and distribution in Ukraine.

    This sample was collected in the Sumy region (province) of Ukraine (north-eastern part of Ukraine). Fruit bodies detect by incubation in moist-chambers.

    I have many samples of S. tetrasporum from Ukraine. But this is the first with such small spores.

    Kindly regards, Yulia.

    Hello Julia,

    there are 3 species wirh 4-spored Asci. S. inaequale, tetrasporum and nanum. The pictures fit perfectly to S. tetraspora, but not the dimensions. S. inaequale and S. nanum have a different spore-shape. I think it is a small-spored Form of S. tetraspora. I postpone this to the coprophilic mushrooms.

    Dear Rada! Thanks for the answer. In the works dedicated to this genus, I also saw only three species with 4-spore asci. I also thought about the fact that this is either the small-spored form of S. tetraspora, or the large-spored form of S. nanum :) I would like to know, maybe someone else had such samples.

    Dear Friends,

    I have one sample of the Schizothecium with 4-spores asci on domestic rabbit dung, over the identification of which I have been suffering for several months.

    Perithecia semi-immersed, dark brown to blackish, broadly ovoid to pyriform; agglutinated scales 25,5-38,7 μm. Asci 4-spored, cylindric-clavate, 90-125 × 12,5-13 μm. Ascospores uniseriate, apical dark cell (head) 15,30-18,41× 8,92-10,57 μm; olivaceous to dark brown, ellipsoidal, with an apical germ pore, somewhat flattened at the base and a slightly umbonate at the apex; pedicel 10 × 2,2 μm; upper cauda lash-like, the lower one similar, attached to distal end of the pedicel.

    This sample will occupy an intermediate between Sch. nanum and Sch. tetrasporum. In the works that I have, there is no fungus with such characteristics.

    Thank you!
