Four new species of Bjerkandera, viz. B. ecuadorensis, B. fulgida, B. minispora, and B. resupinataspp. nov., are described from tropical America and Asia. B. ecuadorensis is characterised by dark grey to black pore surface, a monomitic hyphal system, hyaline to yellowish-brown generative hyphae, and ellipsoid basidiospores measuring 3.9–4.5 × 2.7–3 μm. B. fulgida is distinguished from the other species in the genus by clay buff to pale brown and shiny pore surface. B. minispora is characterised by white tomentose pore mouth and small basidiospores measuring 3.1–4.2 × 2–2.8 μm. B. resupinata is characterised by resupinate basidiomata, pinkish buff to pale brownish pore surface, and ellipsoid to broadly ellipsoid basidiospores measuring 4.5–6 × 3.2–4.1 µm. All these new species grow on angiosperm trunks or rotten wood, and cause a white rot. The closely related taxa to four new species are discussed. An identification key to the ten accepted species of Bjerkandera is provided, and a phylogeny comprising all known Bjerkandera species is provided.

Bjerkandera（Polyporales，Basidiomycota）的系统发育和多样性，包括来自南美和亚洲的四个新物种

Bjerkandera的四个新种，即。厄瓜多尔芽孢杆菌，fulgida芽孢杆菌，minispora芽孢杆菌和resupinataspp。芽孢杆菌。十一月，描述来自热带美洲和亚洲。厄瓜多尔芽孢杆菌的特征是黑灰色至黑色的孔表面，单核菌丝系统，透明的至黄褐色的生成菌丝和椭圆形的担子孢子，大小为3.9–4.5×2.7–3μm。富丽芽孢杆菌与该属中的其他物种有区别，其粘土抛光剂为浅棕色和有光泽的孔表面。微小芽孢杆菌的特征是白色的绒毛孔口和大小为3.1–4.2×2–2.8μm的小的担子孢子。B. resupinata的特征是重生的basidiomata，粉红色的浅黄色至浅褐色的孔表面，椭圆形到宽椭圆形的basidiospores大小为4.5–6×3.2–4.1 µm。所有这些新物种都生长在被子植物的树干或腐烂的木头上，并引起白腐。讨论了与四个新物种密切相关的分类单元。提供了十个公认的Bjerkandera物种的识别码，并提供了包含所有已知Bjerkandera物种的系统发育信息。
