根据形态学和分子生物学特征，将采自中国南方的晚刚毛伪毛藻（Pseudochaete latesetosa）和亚硬毛伪毛藻（P.subrigidula）描述为新种。两种的担孢子均呈狭圆柱形至尿囊状，刚毛具硬壳，这是假毛纲的特征。P.latesetosa与P.tabacina相似，不同之处在于后者的担子果倒着，倒着或倒着，皮层和绒毛层发达。亚硬毛蕨与硬毛蕨相似，但后者的刚毛和担孢子较短。从ITS和nLSU rDNA序列分析推断的系统发育结果表明，这两个物种嵌套在Pseudochaete分支，并从其他采样物种以及彼此分离。这两个物种的说明提供。
Pseudochaete latesetosa and P. subrigidula collected from southern China are described as new species based on a combination of morphological and molecular characters. Both the species have narrowly cylindrical to allantoid basidiospores and encrusted setae, which are diagnostic characters of Pseudochaete. P. latesetosa is similar to P. tabacina, except that the latter has resupinate, effused-reflexed or pileate basidiocarps and well-developed cortex and tomentum. P. subrigidula resembles P. rigidula in macroscopical and anatomical structures, but the latter has shorter setae and basidiospores. The phylogenetic results inferred from analysis of combined ITS and nLSU rDNA sequences show that the two species were nested within the Pseudochaete clade and were separated from other sampled species as well as from each other. Illustrated descriptions of these two species are provided.
