Orbilia eucalypti/coccinella ?
Chris Yeates, 27-01-2013 18:58
Chris YeatesBonsoir tous
found on an attached Quercus twig, growing on old Colpoma quercinum; I am pretty sure that I have collected this before (lower image, with more abundant apothecia); the confused nomenclature does not help - am I correct in thinking that this is what would be now called Orbilia eucalypti? The spore dimensions - 3.8-4.5 x 2.1-2.6µm match O. coccinella here: http://www.librifungorum.org/Image.asp?ItemID=36&ImageFileName=SyllogeFungorum8-628.jpg further down the page the spore dimensions for O. eucalypti seem to be larger . . . .

any help welcome
amitiés
Chris

Hi Chris

yes, it is quite typical O. eucalypti. The type of O. coccinella has reniform (C-shaped) spores, and eucalypti is the oldest available name. The species is actually frequent also in SW-Australia.

Brian Spooner sent me mayn years ago just such collection on Coploma quercinum. But this seems accidental rather than a constant connection. O. eucalypti is plurivorous.

If you tell me the place I will take up the nicely documented collection.

many thanks for that Zotto - details are:
small woodland area, Edgerton, Huddersfield, West Yorkshire
53°39'23.59"N
1°48'25.58"W
145 metres O.D.
05 January 2013
specimen - Herb. CSVY/F/2272

this is very close to where I recorded Hymenoscyphus aesculi: http://www.ascofrance.com/search_forum/19553 - the KMZ file on that thread takes you to the site in Google Earth


vielen Dank und die besten Wünsche


Chris

Re : Orbilia eucalypti/coccinella ?
thanks, that is for me the same place :-)

I overlooked your remark on the type of eucalypti. here a short excerpt of my discussion:

(1) spores 7 × 3.5 µm (an error for 7 × 2.5 µm, according to the sketch in the type convolute in K). .... the asci are with †60–70 µm extraordinarily long, .... and the spores 5.2-7 x 2.1-2.4 µm.

(2) In a rather small apothecium of the holotype the asci and spores were found much smaller than in the large ones (asci †30–38 × 3–3.2 µm, spores †4 × 1.8 µm)

It remains unclear if the type is a mixtum of too very closely related taxa or only one variable species. But O. eucalypti as we apply the name is in fact very variable in spore and ascus size.
