Arthur and Gulielma Lister's *A Monograph of the Mycetozoa* (1894) gathered 78 hand-painted plates of slime moulds — bright sulphur-yellow Physarum sporangia on slender stalks, reticulate plasmodium veins, life-stage sequences fading from fresh yellow to aging brown.
This design system reads those plates honestly: glowing yellow set against the dim decaying-substrate grey the organisms actually grow on, not on cream. Soft watercolour modelling, fine veining linework, and engraved figure numbers carry the period naturalist's hand into the interface.
阿瑟·李斯特与古列尔玛·李斯特合著的《黏菌专论》（A Monograph of the Mycetozoa，1894 年）汇集了 78 幅手绘图版：纤细柄上明亮的硫磺黄色 Physarum 孢子囊、网状的原质团脉络，以及由鲜黄渐渐褪向枯褐的生命阶段序列。
本设计系统忠实还原这些图版的观感——发光的黄色衬在黏菌真正生长的、晦暗的腐殖基质灰之上，而非奶白底。柔和的水彩塑形、纤细的脉络线描与雕版式的图号编号，将这位维多利亚博物学家的笔触带入界面。
