è intervenuto Rod Tulloss (noto studioso americano di Amanita) ed ha definito i miei esemplari:
e poi ha sostenuto che A. flaverscens e A. subnudipes sono specie diverse ed ha postato una sua chiave di determinazione al riguardo...Nice pictures of subnudipes, mefi!
che ne pensate?The likelihood that the two species of Amanita sect. Vaginatae that you have photographed well is that neither is a described species. This is a BIG problem with sect. Vaginatae in North America. I would agree with those who said that orange-brown species resembles what we call "A. fulva" in North America. The problem is that we have it thoroughly wrong. We have a look-alike that needs a name. I have collected A. flavescens in Norway and seen the original material from Sweden. It is a different species from A. subnudipes (=crocea var. subnudipes). There's a key to the species related to fulva, crocea, and romagnesiana at
http://pluto.njcc.com/~ret/amanita/key.dir/crocekey.pdf
This key only deals with the NAMED taxa in a few closely related groups. I hope it is clear that A. flavescens is a northern(?) European species that can be segregated without too much difficulty from A. crocea and A. subnudipes.
Very best,
Rod Tulloss
L'olotipo di Amanita flavescens non corrisponde ad Amanita crocea var. subnudipes?
se ne era già parlato in questo forum -> http://www.funghiemicologia.com/phpBB3/ ... f=5&t=1718
Indexfungorum tiene separate le 2 specie... ...anzi ne fa 3...
