摘要

Dendrodacrys属是一个单系类群,属于泪菌门(Agaricomycotina,担子菌门),包括以强烈分枝的菌丝和3-分开的担子孢子为特征的物种。虽然最初的限定主要针对欧洲分类群,但在这里,我们将重点转移到热带和亚热带的材料上,并揭示了在树endrodacrys中更广泛的形态学变化。仍由菌丝形状和担子孢子分隔统一,本属扩展为10个分类群,具有黄色至深棕色的脓疱状、脑状或具柄的担子果,圆柱形至卵球形的担子孢子和有夹或不带夹的菌丝间隔。通过6个标记(SSU、ITS、LSU、TEF1-α、RPB1和RPB2)的系统发育分析,证实了改良后的树突属植物的单系性。因此,我们描述了两个新种(De. laetum和De. rigoratum),将三个现有的物种转移到Dendrodacrys (De. brasiliense, De. dendrocalami和De. pezizoideum),并将一个品种提升到物种水平(De. kennedyae≡Dacrymyces enatus var. macrosporus)。此外,我们还提供了早期合并的De. aparyysatum和四个新的非正式分类群的描述。最后,我们提出了插图,一个特征表,和一个识别键,地址所有已知的泪霉菌分支菌丝。引用本文:Savchenko A, Zamora JC, Alvarenga R, Kõljalg U, miiettinen O(2022)。担子菌科泪霉菌属枝孢子的增补和枝孢子分类群的轮廓。真菌分类学与进化(10):103-126。doi: 10.3114 / fuse.2022.10.04。

Additions to Dendrodacrys and outline of taxa with branched hyphidia in Dacrymycetes (Basidiomycota).

The genus Dendrodacrys is a monophyletic group that belongs to Dacrymycetes (Agaricomycotina, Basidiomycota) and accommodates species distinguished by strongly branched hyphidia in combination with 3-septate basidiospores. While the original circumscription mainly treated European taxa, here we shift the focus to tropical and sub-tropical material and uncover wider variation in morphology within Dendrodacrys. Still united by hyphidia shape and basidiospore septation, the genus is expanded with 10 taxa having pustulate, cerebriform, or stipitate basidiocarps of yellow to dark brown colours, cylindrical to ovoid basidiospores, and hyphal septa with or without clamps. Monophyly of the amended Dendrodacrys is confirmed with a phylogeny based on six markers (SSU, ITS, LSU, TEF1-α, RPB1, and RPB2). As a result, we describe two new species (De. laetum and De. rigoratum), transfer three existing species to Dendrodacrys (De. brasiliense, De. dendrocalami, and De. pezizoideum), and raise one variety to the species level (De. kennedyaeDacrymyces enatus var. macrosporus). In addition, we provide descriptions for the earlier combined De. paraphysatum and four new informal taxa. Lastly, we present illustrations, a character table, and an identification key that addresses all known dacrymycetes with branched hyphidia.
