Lachnum ?callimorphum
Nina Filippova, 24-02-2013 17:38
I was going through the key by Raitviir (1970) to come to this species; but Lachnum's are so numerous that id seems so uncertain..

Growing on Carex limosa leaves, in bog.

Apothecia stipitate, white with white or yellowish hymenium, disc to 0,5 mm in diam, all frb to 300 mk high, stipe about 150 mk high; edge ciliate from hairs (lens), outer surface and stipe covered by hairs as well.


Excipulum textura porrecta/prismatica at stem, textura globosa/prismatica at flanks, cells with thickened walls, about 10 x 6,5; hairs with broadened base and tip, grow from 1-2 globose cells at base, measured length x width at neck x width at tip: 47-70 x 2-3 x 3-5; asci cylindrical, clampless, pore amyloid, 33-44,5 x 3,5-4,2; paraphyses lanceolate, exceeding the asci for 30 mk, broadest ipart in the middle of length, wih 2-3 septa in basal part, sometimes with 2-3 outbranches in basal part, 63-73 x 2,6-3,4 (width in broadest part); spores narrow-fusiform, with small guttules at the ends, 14 (12,2-16,6) x 1,5 (1,4-1,6) (Q=9,5; N=17).

Re : Lachnum ?callimorphum
Hello.
Hairs doesn't seem to be incrusted, but maybe they are so finely...
Nina Filippova, 24-02-2013 17:54
Re : Lachnum ?callimorphum
Well encrusted, actually). Some out of focus, but they completely rough at entire length.

Re : Lachnum ?callimorphum
I do not believe that it is callimorphum, which I do not know. But look at Dennis' 1963 type description: the hairs lack an apical inflation.

We do not know if your species has guttules in the paraphyses, but since it does not seem to change reddish with age, I assume it hasn't. 

L. imbecille has much larger spores and a reddish hymenium.  L. tenue has shorter spores. But what about Lachnum schoenoplecti? I noticed spores up to 28 x 2.3 µm, but also 12-20 x 1.6-1.9 (live).

Re : Lachnum ?callimorphum
Hello, Zotto.

This specimen do not have reddish in color, and not turn reddish/brownish on drying, right.

I looked at at your specimens of L. schoenoplecti, it looks similar. Praphyses in mine more protruding above the asci. Host - yours 5688 collected from Carex as well? I downloaded your paper with sp. nov. description, will read it.

Re : Lachnum ?callimorphum
Yes, 5688 is on Carex ?acutiformis. 12-28 µm protrusion is very much, you say 30 µm, almost incredible :-)

But protrusion is less so in the living state. In the protologue, 10-15 µm seems to refer to living asci.

here is the original article
