Hello everyone, On 08/04/26, I found a growth sit
Bonsoir tousfound 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

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.

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

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.
