Mollisias and others.

[Gerel]

The following were all found growing on dead deciduous wood in mixed woodland. This woodland is predominantly oak but also contains ash, hazel, birch and fir.

Two Mollisia types, found, I think, on dead oak.

1.

2.

Growing on a rotten stump, this looks like a Lachnum sp., (L. impudicum?)



Finally, on what looks like an ash twig, a collection of small fungi including this tiny white fruit body. For scale the twig is roughly the thickness of a finger.

Nice one, looks quite "hairy", so I would not be surprised if it turns out NOT to be M. cinerea. But for me no chance withou detailed microscopy.

2.

Not sure whether this is the same. It looks much smoother then the other. Don't be influenced by the colour, they can without problem be the same species from that sight. Also this ones look like an albinotic form, because the outside also seems to be white instead of brown?

quite unlikely, in my opinion. On dead truncs of Quercus in winter you have in most cases Dasyscyphella nivea. You can immediately see the difference between this and any Lachnum species when looking at the paraphyses (not lanceolate in Dasyscyphella) or at the hairs (with a smooth and inflated end cell in Dasyscyphella).

Finally, on what looks like an ash twig, a collection of small fungi including this tiny white fruit body. For scale the twig is roughly the thickness of a finger.

This looks like a very young fruitbody of a Hemimycena. The middle foto seems to show that it has cystidia on the cap and on the stipe. There are no Mycenas which have cystidia on the cap.

Except M aciculata All right I know they are just hairs.

Probably H. crispula or might just be H tortuosa both of which have hairy cap and stipe

Hi, thanks for your comments, as always

I hoped that you'd like the first two Andreas, unfortunately I can't supply microscopy yet. The best I can do is a slightly clearer shot of number 1. It definitely does appear to be hairy outside.



And here is another one I picked up today. Smaller than than the first two the discs of this were all <1mm across whilst the some of the others were >2mm.



I'll try to get some better shots of the Dasyscyphella nivea and label them correctly, thanks.

There were a number of the small white Hemimycena sp. on the twig, all much the same size. (The close-ups are of two different individuals.) I'll try to keep an eye on them as they develop. Are there any macroscopic features to look for to separate the two you suggest Mal, or is that another microscopy job?

Cheers

Unless you have VERRRRY good eyes it's a microscope job

Hallo Gerel,

small ascomycetes, the so-called inoperculate ascomycetes are for 99% of the species undeterminable without proper microscopy. If you have gained much experience by using microscop, you will recognize the one or other species more by macroscopy. So then it's only 98% which need in all cases the microscope ...
So no need for new shots of Dasyscyphella nivea when there is no chance to look in a microscope. These white hairy ascos are undeterminable eben with a hand lens.

Your new unknown asco with the yellowish hymenium and the yellowish hairs is very likely to be Neodasyscyphus cerinus. This is one of the few which can often be determined without microscope.

best regards,
Andreas
