There are two close species which are going to be send to Danny Halewartes soon for detailed study, but i also wanted to show them here.

Plus I am sending to him these taxonomically related earlier posted samples:
Cyathicula starbaeckii http://www.ascofrance.fr/search_forum/22273
Crocicreas gramineum http://www.ascofrance.fr/search_forum/22254

The first species is close by macro-morphology to Stamnaria persoonii, but has spores more cylindrical, paraphyses of two types and its host is different (E. sylvaticum).

Stamnaria sp., Kh-3519, 09.06.2012, 61,070617N 69,468112E, Russia, Khanty-Mansiyskyi avtonomniy okrug, Khanty-Mansiysk, Shapsha village, Coniferous mixed forest. On litter of Equisetum sylvaticum.

Apothecia turbinate, stipitate, 0.4-0.6 mm in diameter in mature state, 0.5-0.7 mm height; yellow with whitish collar and translucent stem when alive, becoming light brown on drying; when dry collar closes the hymenium making flat crest; scattered abundantly on branches of Equisetum sylvaticum.

Outer layer of apothecium made by gelatinose loosely more or less parallel hyphae, septate, 2-3 mk broad; inner layer of excipulum made from textura prismatica, cells of middle flanks near 30 x 10 mk, shorter to the edge; medulla well developed from wide segmented hyphae, cells near 50 x 7 mk; subhymenium well developed, from intricate hyphae; raising under the hymenium part (collar) has inner layer made from similar to gelatinose narrow hyphae, free upper part of these hyphae covered by warts (outgrowths).

Asci cylindrical, ascus development starts from crozier, barely seen in mature asci, with apical thickening, with euamyloid ring of "Calycina-type", †98 x 9 (90-110 x 8-10.5) mk (measured in dead state); paraphyses of two types; first type of lanceolate paraphyses exceed asci for 30-40 mk, segmented in lower part, lanceolate in upper part with quite acute tip, vacuolar content in vital state not observed, †100-130 mk long and 3-6 mk broad in lanceolate part; second type of cylindrical paraphyses more abundant, not exceed the asci, †80-100 mk long and about 2 mk broad, segmented, cylindrical with obtuse tip, rarely branched and scarcely some enlarged in upper segment; spores fusiform, slightly heteropolar, with obtuse ends, guttulate (but character of guttulae not observed in vital state), †22 x 4.2 (19.4-23.6 x 3.8-4.6) mk, n=20, Q=5.3.

Re : Stamnaria and related

These are big news, Nina! I am very curious about the genetic result of Crocicreas gramineum.


Yes for the second sample, C. cyathoidea at least in a wide sense. How did you keep it alive over the years? ;-)

The paraphysis content is not oil but vacuoles, and every living paraphysis has it.

About your first sample here, it did not survive, regrettably. It really looks like a Stamnaria, but the very atypical paraphyses remind me of Crocicreas too, also the apical ring. We will see, hopefully.
