Penicillium dravuni is a new monoverticillate, sclerotium-forming species that was isolated from the alga Dictyosphaeria versluyii collected in Dravuni, Fiji. This species morphologically is similar to P. turbatum in the P. turbatum subseries of the P. thomii series of the Monoverticillata. The nuclear ribosomal internal transcribed spacer region exhibited 97% sequence similarity to known Penicillium spp. in the GenBank database. Phylogenetic analyses revealed that P. dravuni is related most closely to Eupenicillium brefeldianum, E. levitum, E. reticulosporum, E. javanicum, E. ehrlichii and PF simplicissimum. However this new species shares only a distant ancestor with this clade because it branches by itself early in the lineage. P. dravuni also is known to produce the secondary metabolites dictyosphaeric acids A and B and carviolin.
德拉武尼青霉是一种新的单轮生、形成菌核的物种，它是从斐济德拉武尼采集的藻类多歧线盘藻中分离出来的。该物种在形态上与单轮生组特异青霉系列特异青霉亚系列中的曲霉菌相似。核糖体DNA内转录间隔区与GenBank数据库中已知的青霉属物种表现出97%的序列相似性。系统发育分析表明，德拉武尼青霉与布雷费尔德正青霉、上升正青霉、网状孢正青霉、爪哇正青霉、埃氏正青霉和简单拟青霉关系最为密切。然而，这个新物种与该进化枝只有一个遥远的共同祖先，因为它在谱系中很早就独自分支了。德拉武尼青霉还已知会产生次级代谢产物多歧线盘藻酸A和B以及香芹醇。
