在具有蓝紫色-紫色子实层表面的Peziza复杂类群中，Petersii、P. proteanaff. Proteana和F. sparassoides进行了研究，使用形态学和分子方法（nrITS和RPB 2序列分析）。成功地从变形粉虱、假紫粉虱和康氏粉虱的全型中获得了nrITS序列。对该菌的nrITS和RPB 2区进行了序列测定。结果表明：（1）变形原甲藻和彼得原甲藻为一个种，彼得原甲藻为Berk.发表于1875年和Aleuria proteana Boud。in 1899，the prioritary name is the former;（ii）P. proteana f. sparassoides（Boud.）Korf，“卷心菜头真菌”，是一个独特的进化线，在这里被认为是在物种水平上使用最古老的可用的绰号，可以在Peziza，Underwoodia campbellii Sacc中组合。因此，引入了Peziza campbellii nov. comb.。
Amongst the complicated group of Peziza with blue-violet-purplish hymenial surface, P. petersii , P. proteana f. proteana and f. sparassoides were studied using both morphological and molecular approaches (analysis of the nrITS and RPB2 sequences). The nrITS sequences were successfully obtained from the holotypes of Aleuria proteana , P. pseudoviolacea and Underwoodia campbellii . The epitype collection of P. petersii was designated, and its nrITS and RPB2 regions were sequenced. Our analyses showed that (i) P. proteana and P. petersii are a single species, and since P. petersii Berk. was published in 1875 and Aleuria proteana Boud. in 1899, the prioritary name is the former; (ii) P. proteana f. sparassoides (Boud.) Korf, the “cabbage-head fungus”, is a distinct evolutionary line and is here recognised at species level using the oldest available epithet that can be combined in Peziza , Underwoodia campbellii Sacc. Consequently, Peziza campbellii nov. comb. is introduced.
