Unguicularia?
Steve Clements, 27-04-2015 21:06
Hi,
I used Fungi of Switzerland and W.G. Dennis (A Revision of the British Hyaloscyphacaea)in coming to a possible genus for this asco – with the very refractile hairs (FOS), and a lumen at the base only (Dennis) combined with urniform shape and minute size. However, I have read that the hairs of Unguicularia dissolve on heating in KOH solution – these didn't.
On very rotten wood – likely Fagus, in small groups. Sessile, urn-shaped, maximum 0.3mm diameter, 0.2mm height. Colour white. Surface minutely hairy. Spores 6-8 x 1.5-2 – maybe with polar guttules. Asci with croziers (some) about 40x5: reaction with Lugol: contents reddening, tip darkening rather than blueing. Hairs(?) highly refractile, irregular, with lumen at base, up to 5 wide, not dissolving on heating in 10% KOH. Paraphyses thread-like, about 1 micron wide.
I suspect this is a difficult fungus – any advice would be very welcome,
Kind regards,
Steve

Re : Unguicularia?
Hi Steve
I think I have sent you Raitviir's "Revised Synopsis of the Hyaloscyphaceae"? If not let me know  . . . .
I think this will prove to be Olla millepunctata (= Unguicularia scrupulosa amongst other names). Compare with http://www.ascofrance.com/search_recolte/3993

cheers
Chris

Re : Unguicularia?
The ascus base should be without croziers, actually. I prefer to separate scrupulosa for those on wood, with slightly wider asci and spores.

Re : Unguicularia?
Many thanks Chris and Zotto,
yes - I wasn't too convinced about the croziers.
I have just spotted the Raitvir paper on my overcrowded desktop!
Cheers,
Steve

Re : Unguicularia?
Hi,
I have run my findings through the key for Olla in Raitviir, and apart from the details on excipular cells (which I found hard to differentiate in my squash preparation) my data is a good match for Olla millepunctata. I see that Congo Red and Meltzer's were used in Raitviir, as well as KOH.
Kind regards,
Steve
