本文对澳大利亚南部红藻门顶毛藻-红毛藻复合体的形态学和分类学进行了研究。顶毛菌属和红毛菌属的模式种都被归入Audouinella属，该属现在被称为Audouinella复合体。该地区有两个属：Audouinella（syn. Acrochaetium，Balbiania，Chromastrum，Grania，Rhodochorton），已知有性繁殖，包含12个南澳大利亚物种（包括A。（Blumii sp. nov.）Colaconema，在此作为一个可与半知菌类的形态属相比较的属处理，包含14个澳大利亚南部形态种，所有这些种的性态都是未知的。本研究不支持Feldmann（1962）、Kylin（1956）和Papenfuss（1945，1947）的属分类建议。audouinelloid藻类的形态特征很少的一般系统的价值，但核的数量，孢子囊的尺寸，和细胞的尺寸似乎是系统的目的最可靠的标准。其他特征（例如，匍匐系统的形式，染色体形状，毛的发生和位置，spennatangial形态，以及受精后立即发育）显示出太多的变异，不能可靠地用于种和！或一般的分离。简要介绍了热带澳大利亚种的信息。
The morphology and taxonomy of the southern Australian representatives of what has been frequentiy referred to as the "Acrochaetium-Rhodochorton" complex of the Rhodophyta have been studied. The type species of both Acrochaetium and Rhodochorton are placed in the genus Audouinella and the group is now referred to as the Audouinella complex. Two genera are recognized in this region: Audouinella (syn. Acrochaetium, Balbiania, Chromastrum, Grania, Rhodochorton), known to reproduce sexually, contains 12 southern Australian species (including A. blumii sp. nov.) and is referred to the Audouinellaceae nom. nov. Colaconema, treated here as a genus comparable with form genera of the Fungi Imperfecti, contains 14 southern Australian form species, all unknown in the sexual state. The generic classification proposals of Feldmann (1962), Kylin (1956), and Papenfuss (1945, 1947) are not supported by this study. Few morphological features of audouinelloid algae are of general systematic value, but pyrenoid numbers, sporangial dimensions, and cell dimensions appear to be the most reliable criteria for systematic purposes. Other features (e.g. fonn of the prostrate system, chromoplast shape, occurrence and position of hairs, spennatangial morphology, and immediate post-fertilization development) show too much variation to be used reliably in species and!or generic separation. Infonnation on the tropical Australian species is briefly summarized.
