Hysteropezizella sp.

It has similar to H. diminuens spores, but shorter, asci there actually inamyloid, and paraphyses shape and incrustation very different.
At Carex rostrata, C. limosa leaves.
Apothecia submerged in leaf tissue, opening by ellipsoid lid, disc convex, white from reachly incrusted paraphyses.
Excipulum from textura globosa-angularis at base and flanks, end cells fusoid, to 50 mk long, with brown content, encrusted; asci with inamyloid pore (after KOH, heat, MLZ), 70-82 x 10,3-13,4; paraphyses strongly encrusted, exeeding the asci up to 50 mk, with cylindrical lower half and fusoid upper, upper segment with yellowish-brown content, 3,3 mk at base, 8,6 in largest part; spores subfusoid, two-guttulate, 15,3 (14,4-16,2) x 4,4 (4,2-4,6) (Q=3,5; N=14).

Re : Hysteropezizella sp.
Yes, Hysteropezizella, but compare also Coronellaria. Important here (and also the other species of the complex) is to look for the croziers, which are species-specific.

Re : Hysteropezizella sp.
Hi Zotto,
i was studying you paper about Coronellaria spec. (2008) and corrected observations of my specimens.
There was mistake in the description, actually ascus pore is RR in lugol, and becoming blue after koh pretreatment. I studied several apothecia to be sure that there is no mix of species, and i think there was only one. Asci without croziers. The excipulum brown (though sometimes, i suppose in underdeveloped frbs, hyaline).
Probably C. caricinella?

Re : Hysteropezizella sp.
Yes I also suppose Coronellaria caricinella s.l. The form without croziers is typical of mountainous sites in Central Europe. What is the locality you found it, has it a high altitude?

Re : Hysteropezizella sp.
Not mountainous - it is plain, almost at sea level. But it is 61° North latitude. In ombrotrophic bog landscape.
Tnank you.

Re : Hysteropezizella sp.
So it is boreal. Interesting indeed. C. caricinella is by Karsten, so should be also boreal. Would be necessary to examine the type for the ascus base.
By the way, what I want to see in fresh state since decades is Crocicreas gramineum. I suspect it is also boreal - subalpine. On various monocots. Did you even encounter it?

Re : Hysteropezizella sp.
Yes, it is boreal zone.
There are three collections prior marked as "Crocicreas", but not identified them yet. I looked at your drawings of C. gramineum, and one of them may be similar. It is from Milium effusum dead leaves. I will microscopy them soon.

Re : Hysteropezizella sp.
yes, could be. But must have lanceolate paraphyses.

Re : Hysteropezizella sp.
Coronellaria caricinella s.l. now commonly seen on Carex limosa fallen leaves. But the measurements of vital structures some different from the previous in dead; and there are the pictures of them.
Apothecia circular to ellipsoid, submerged in tissue, with more or less pronounced dark edge, opening by a circular lid or sometimes irregularly, hymenium surface white powdery when dry, flat to convex, 200–330 mk by long axis, 120–220 mk broad.
Asci clavate, without crozier, mean size in mature specimens 76–114 x 15–17.5 (much shorter when young), with hemiamyloid pore (water - lugol), amyloid reaction appears after KOH pretreatment with heat; paraphyses lanceolate, enlarged in upper part, with acute tip, 5-6 segmented, lower part filled with pale roound VBs, and other kind of tiny vacuoles (oils?) collected in the tip, upper part well incrusted, medium size 113 x 7; spores foot-shaped, with several medium and many small oils at each end, 18.4 (17–19.8) x 5.7 (5–6.8) (n=15).?

Re : Hysteropezizella sp.
Another relative species was noticed as well: the apothecia here are superficial, stipitate, and the size of asci, paraphyses, spores is smaller, content of paraphyses also differ. Probably another Caricinella sp. (or may be it is some variation of the previous one)?.
Apothecia cupulate, superficial, sessile to short-stipitate, white, hymenium powdery, 130–260 mk in diameter, 150–260 high.
Excipulum from hyaline cells (brownish in stem), prismatica, edge from similar to paraphyses lanceolate incrusted structures; asci clavate, without crozier, with hemiamyloid pore, medium size 80 x 12.3; paraphyses cylindrical, with lanceolate not broad upper part, many segmented, VBs of the size of segments, tip incrusted (incrustation turn bright rusty in YKY), medium size 85 x 4.4; spores foot-shaped, with several small oils at the ends, 14.8 (13.3–16.2) x 4 (3.8–4.4) (n=14).?

Re : Hysteropezizella sp.
Yes, and you already stated that the altitude is very low (almost sea- level), which is strange since my finds of those without croziers are mointainous.
