The species diversity of corticolous myxomycetes on 4 vegetation types in the Tianmu Mountain National Natural Reserve, eastern China, was examined from 2011 to 2012. A total of 1440 moist chamber cultures were prepared with bark samples, which yielded several hundred collections representing 42 species in 20 genera. It was found that 79% of cultures produced some evidence (either plasmodia or fruiting bodies) of myxomycetes. Eight species (Comatricha elegans, Cribraria confusa, Licea pusilla, Cribraria microcarpa, Collaria arcyrionema, Licea biforis, Arcyria cinerea, and Clastoderma debaryanum) were abundant (exceeding 3% of all records), but about a third of all species were classified as rare. Species richness (S = 33) and diversity (exp[H'] = 16.60, S/G = 1.74) of corticolous myxomycetes were the most diverse in the deciduous broadleaf forest. The species recorded from coniferous forest showed the lowest species richness (S = 21) but the highest evenness (J' = 0.91). The cluster analyses were based on the Bray-Curtis similarity matrix, and the results indicated that corticolous myxomycete assemblages were distributed by a seasonal and annual pattern. Canonical correspondence analysis showed that season and pH were key factors in determining species distribution.
2011 年至 2012 年，对中国东部天目山国家级自然保护区的 4 种植被类型的树皮附生粘性菌进行了物种多样性调查。共准备了 1440 个湿室培养物，用树皮样本进行培养，得到了数百个代表 20 个属的 42 个种的标本。结果发现，79%的培养物产生了粘性菌的某些证据（无论是原质团还是子实体）。8 种（Comatricha elegans、Cribraria confusa、Licea pusilla、Cribraria microcarpa、Collaria arcyrionema、Licea biforis、Arcyria cinerea 和 Clastoderma debaryanum）丰富度较高（超过所有记录的 3%），但约三分之一的物种被归类为稀有物种。树皮附生粘性菌的物种丰富度（S=33）和多样性（exp[H']=16.60，S/G=1.74）在落叶阔叶林最高。从针叶林记录的物种显示出最低的物种丰富度（S=21），但最高的均匀度（J'=0.91）。聚类分析基于 Bray-Curtis 相似性矩阵，结果表明树皮附生粘性菌组合受季节性和年度模式分布。典范对应分析表明，季节和 pH 值是决定物种分布的关键因素。
