Small agarics are poorly documented in Taiwan, with previously reported species either rudimentarily described or lacking a description or diagnosis in most cases. A survey on small agarics in a lowland forest of Taiwan revealed two species previously unrecorded.
One agaric, which is characterized mainly by white hairs overlying the pileus, a conspicuous cup-shaped basal disc surrounding the stipe, and inamyloid basidiospores, fits the genus Mycena and appears undescribed. It readily produced abundant basidiomata in culture in three weeks. The other agaric is Gloiocephala epiphylla, being characterized by its reduced hymenium and conspicuous pileogloeocystidia. ITS sequences from the two agarics further corroborated the identifications. Their macroscopic and microscopic features and culture morphology are described. A dichotomous key is provided to the species of Mycena reported in Taiwan.
The Mycena species is newly described as M. albopilosa herein. Gloiocephala epiphylla is new to Taiwan, being the only species of the genus known on the island.
台湾地区小型伞菌的记录很少，之前报道的物种大多描述简略，或缺乏描述或诊断。对台湾低地森林中的小型伞菌进行的一项调查发现了两个以前未记录的物种。
一种伞菌，其主要特征是菌盖上覆盖着白色绒毛，菌柄周围有明显的杯状基部菌托，以及非淀粉质的担孢子，符合 Mycena 属，似乎未被描述过。它在三周内就能在培养物中大量产生子实体。另一种伞菌是附生球盖菇，其特征是子实层减少和明显的菌盖胶胞。这两种伞菌的 ITS 序列进一步证实了鉴定结果。描述了它们的宏观和微观特征以及培养形态。提供了一个台湾报道的 Mycena 属物种的检索表。
这里将 Mycena 物种新描述为白绒毛 Mycena。附生球盖菇是台湾新记录种，是该属在岛上已知的唯一物种。
