Actually Larsson & Jeppson (2008) offered a transfer of Vascellum into Lycoperdon (as subgenus). The problem is that they included only a sequences from Vascellum pratense and Vascellum cfr intermedium in their results. So, formally only these two entities from Vascellum can be transfered to Lycoperdon (as is done in Species Fungorum). The rest of Vascellum is waiting for proof that their sequences are falling into the same clade and I think this is why Vascellum is still independent genus in Species Fungorum.
Looking at the good presence of eucapillitium (plus paracapillitium) on the rather good drawing I would bet for Lycoperdon (=Vascellum)lloydianum, but without the necessary confidence:)!
I wish you had cut it in half so that I can see how delineated the diaphragm is. According to Scott Bates (U of Arizona) V. lloydianum has more capillitia than V. pratense. Also, V. lloydianum has a less delineated diaphragm than V. prtense (the later having a well defined diaphragm). Both have paracapillitium that are septate and abundant. Both with about the same size spores, and they are asperulate with a small pedicel.
I do not recall L & J putting Vascellum in with Lycoperdon, and I know that there has not been a name/Genus change to move Vascellum into Lycoperdon. My thesis (monograph of the true puffballs of California) is recognizing Vascellum as a group, and possibly Handkea (slit-like pored Calvatia puffballs). I can send you the Larson/Jepson paper on the European taxa if you send me your email. I can also send you the Bates/Desjardin paper published in 2009 using Arizona taxa of puffballs. Vascellum and Lycoperdon are treated as a separate genera of puffball.
1) We don’t have an access to Larssen & Jeppson’s article (they want $31.50 for it) to find out if they have transferred Vascellum lloydianum into the genus Lycoperdon. Has it been done?
2) From his experience with vascular plants, Adolf claims that plants really do not care how they are called. We guess that mushrooms may have a similar lax attitude.
3) We are using the names and their authorities as they appear in the Index/Species Fungorum. This makes our lives and the lives of the MO users easier. – Oluna & Adolf
