A new Penicillium species, P. excelsum, is described here using morphological characters, extrolite and partial sequence data from the ITS, β-tubulin and calmodulin genes. It was isolated repeatedly using samples of nut shells and flowers from the brazil nut tree, Bertolletia excelsa, as well as bees and ants from the tree ecosystem in the Amazon rainforest. The species produces andrastin A, curvulic acid, penicillic acid and xanthoepocin, and has unique partial β-tubulin and calmodulin gene sequences. The holotype of P. excelsum is CCT 7772, while ITAL 7572 and IBT 31516 are cultures derived from the holotype.
本文利用形态特征、次生代谢产物以及来自ITS、β-微管蛋白和钙调蛋白基因的部分序列数据，描述了一种新的青霉属物种——卓越青霉（Penicillium excelsum）。该物种是从巴西坚果（Bertolletia excelsa）的坚果壳和花朵样本，以及亚马逊雨林树木生态系统中的蜜蜂和蚂蚁中反复分离得到的。该物种能产生安曲霉素A、弯孢霉菌酸、青霉酸和黄青霉素，并且具有独特的部分β-微管蛋白和钙调蛋白基因序列。卓越青霉的模式菌株为CCT 7772，而ITAL 7572和IBT 31516是源自模式菌株的培养物。
