Hello,

Benkert & Schumacher (1985, Agarica 6(12): 28-46) stated in their emendation that the genus Ramsbottomia differs from Lamprospora in not being bryoparasitic, having ectal excipulum of t. globulosa or globuulosa-angularis, and having smooth margin (not crenulate / frayed like Lamprospora). I don't know if there are any molecular data on the Ramsbottomia-Lamprospora relationship. 

There should be short and thick thin-walled hyphoid hairs on the receptacle, either hyaline or light brown. If the latter, you might compare R. lamprosporoidea too (if you acknowledge it as good species and not a synonym of R. asperior). I haven't seen yet the spore sheath to survive to their maturity, usually it disappears sooner. Some Scutellinias have similar one - S. trechispora or legaliae. 

It's a very nice genus, I'm always glad when I find it, but I think it needs some molecular work to clarify how many species there actually are (2, 3, or 4, in different authors' concepts) and how to distinguish asperior from crechqueraultii (is the primary character ornamentation height or less globose shape?).

Viktorie and Gilbert, thank you for your comments.  Would either of you happen to have a copy of the Benkert & Schumacher (1985, Agarica 6(12): 28-46) paper that you could share with me?
