Orig. Desc. "Initio maji in dorso foliorum Berberis vulgaris macula flava 

 prodit, tandem in faciem usque penetrans; hie semper plana, illic vero 

 in verrucam convexam magis minusve elata; ex qua emergunt funguli 

 aggregati minutissimi aurantiaci, in principio subrotundi, dein, dum 

 augentur, magis ovati a, rarius obverse ovati b, turn oblongi cum aperto 

 apice c, et tandem cylindrici cum margine crenato et pallente d; 

 figuris hisce in icone ad lentem auctis. Ad hunc usque marginem 

 fungulus impletur substantia solida et aurantiaca, quae maturata sol- 

 vitur tota in pulverem subtilissimum concolorem, excussum ex cylin- 

 dris folia ipsa applentem. Rarissime illos in foliorum facie proprona 

 observavi; nonnunquam pedicellos et caljcem denso agmine circum- 

 dare vidi. Solitarium dumtaxat unum alterumve inveni. In sola Ber- 

 beri hue usque occurrit, nee in alio ulto vicino frutice. Maturescunt 

 mense Junio. Valde accedit ad Lycoperdon penicilliforme Florae 

 Danicae."

I. ./Ecidia on more or less thickened and discolored spots, 

 usually in small groups, but when upon growing lateral shoots 

 often covering large areas; margin prominent, white, erect, 

 more or less jagged; ascidiospores orange-yellow, becoming 

 pale yellow after long desiccation, isodiametric, polygonal, 

 14-24 f* in diameter; wall rather thin, smooth, or sometimes 

 rugulose especially upon one side. 



II. Sori large, oblong to linear, amphigenous, either scat- 

 tered or confluent into rather large, definite groups, more 

 usually found on the leaf-sheaths, soon naked, ruptured epi- 

 dermis prominent, ferruginous; uredospores elliptic-oblong or 

 obovate, often somewhat constricted in the middle, 19-38x14- 

 22 fi, brownish-yellow when fresh, becoming yellow with 

 desiccation, echinulate; pores usually four, equatorial.
