A novel fungal species, Aspergillus labruscus sp. nov., has been found in Brazil during an investigation of the fungal species present on the surface of grape berries (Vitis labrusca L.) for use in the production of concentrated grape juice. It seems to be associated to V. labrusca, and has never been recovered from Vitis vinifera. This new species belonging to Aspergillus subgenus Circumdati section Nigri is described here using morphological characters, extrolite profiling, partial sequence data from the BenA and CaM genes, and internal transcribed spacer sequences of ribosomal DNA. Phenotypic and molecular data enabled this novel species to be clearly distinguished from other black aspergilli. A. labruscus sp. nov. is uniseriate, has yellow mycelium, poor sporulation on CYA at 25 °C, abundant salmon to pink sclerotia and rough conidia. Neoxaline and secalonic acid D were consistently produced by isolates in this taxon. The type strain of A. labruscus sp. nov. is CCT 7800 (T) = ITAL 22.223 (T) = IBT 33586 (T).
一种新型真菌物种， Aspergillus labruscus sp. nov.，在对用于生产浓缩葡萄汁的葡萄浆果（ Vitis labrusca L. ）表面存在的真菌物种进行调查时在巴西被发现。它似乎与 V. labrusca 有关，从未从 Vitis vinifera 中回收过。本文使用形态特征、外生代谢产物分析、来自 BenA 和 CaM 基因的部分序列数据以及核糖体 DNA 的内部转录间隔区序列，描述了属于 Aspergillus 亚属 Circumdati 节 Nigri 的这个新物种。表型和分子数据使这个新物种能够与其他黑曲霉明显区分开来。A. labruscus sp. nov. 是单轴的，有黄色菌丝，在 25°C 的 CYA 上产孢不良，大量鲑鱼到粉红色的菌核和粗糙的分生孢子。该分类群中的分离株一致产生新诺林和 secalonic 酸 D。A. labruscus sp. nov. 的模式株是 CCT 7800（T）= ITAL 22.223（T）= IBT 33586（T）。
