Hi Chris, you can download it for free at Sydowia's website.
Cheers,
Jacques

Thanks Jacques

I thought that was the case, and I'm sure I am being really foolish here, but I can't see how . . . . I know that vols up to 30 are available on Cyberliber http://www.cybertruffle.org.uk/cyberliber/59633/index.htm

But I can't see anything on the Sydowia homepage http://www.sydowia.at/index.htm

Enjoy Rosellinia!

Thanks both - worked fine
and it has confirmed that my collection is what would have been called Rosellinia britannica based on rather flattened perithecia, disappearing subiculum, straight, full length, germ slits, gel caps on spores, and size of spores and ascal tips.

I notice from Jacques' comments on a different AscoFrance thread that there can also be a gel presence along the straighter side of the ascospores. In a number of spores in my collection this was continuous with one or both 'gel caps' (see arrow in accompanying images.

Interestingly in this collection the spores tended towards the shorter end of the range - 20.5-25.6µm - and the ascal tips were longer (often up to 9-10µm long, and I took care not to distort them by too much pressure).

I note also that "R. britannica" has disappeared as a synonym of R. marrucciana (happily not as a result of Brexit!). Presumably Petrini had the opportunity to examine the type, as the protologue http://www.librifungorum.org/Image.asp?ItemID=7&ImageFileName=SyllogeFungorum1-257.jpg implies spores too short).

Amitiés
Chris

great images Chris, you got all the important details! and good to see you did not "brexit" the forum!
Best,
Jacques
