Myxomycetes (Amoebozoa) can be found on a wide range of substrates and among these, the dung of several animal species, primarily herbivorous, in which case they are considered fimicolous. Dung can be a favourable substrate for myxomycete due its relatively high content of water, nutrients and microorganisms. Despite efforts to study fimicolous myxomycetes, there are still informational gaps on the geographical distribution and microhabitat details. Also, scientometric information on these organisms is scarce. This work was aimed to compile the occurrence of fimicolous myxomycetes, from published literature, for the period between 1900 and 2017, resulting in an update on their biogeographical and ecological information. Scientific production involving fimicolous myxomycetes is also discussed. Ninety-eight articles were retrieved, from which authors recorded a total of 544 occurrences classified in 126 myxomycetes species. These records were geographically associated with 51 countries, located primarily on the northern hemisphere. Most occurrences were reported on herbivore dung, mainly from cattle, horse, deer, rabbit/hare, sheep and camel. Arcyria cinerea, Didymium difforme, D. iridis, D. squamulosum, Fuligo cinerea, Kelleromyxa fimicola, Licea tenera, Perichaena chrysosperma, P. corticalis, P. depressa, Physarum apiculosporum, Ph. compressum, and Ph. didermoides were the most frequent species, with at least 10 records each. Despite an increase in scientific production on fimicolous myxomycetes during the studied period, the number of researchers dedicated to this group is low and the inter-institutional collaboration could be improved. It was observed that most authors have produced only one publication, claimed not to be specialists on the group and that tropical fimicolous myxomycetes have clearly been understudied. It is suggested that thematic networks and methodological standardization in molecular studies could increase and improve research on fimicolous myxomycetes. We highlight the importance of the inter-institutional partnership between researchers interested in the study of fimicolous myxomycetes, once access to these technologies is limited for many researchers, especially those in underdeveloped countries, such as Latin American, the formation of collaborative networks may facilitate the application of molecular approaches.

粘菌（Amoebozoa）可以在多种底物上找到，其中包括几种动物的粪便，主要是草食性的，在这种情况下，它们被认为是有丝状的。粪便由于其水，养分和微生物的含量相对较高，因此可能是粘菌的理想基质。尽管努力研究了纤维状粘菌，但在地理分布和微生境细节方面仍然存在信息空白。此外，关于这些生物的科学计量信息也很少。这项工作旨在从公开文献中收集1900年至2017年期间的纤维状粘菌的发生情况，从而更新其生物地理和生态信息。还讨论了涉及纤维状粘菌的科学生产。共检索到九十八篇文章，从中，作者记录了544种情况，分类为126种粘菌菌种。这些记录在地理上与51个国家/地区相关，这些国家/地区主要位于北半球。据报告大多数发生在草食动物粪便上，主要来自牛，马，鹿，兔/野兔，绵羊和骆驼。Arcyria灰霉病，钕镨difforme，D.发红，D. squamulosum，Fuligo灰霉病，Kelleromyxa fimicola，利恰甘紫菜，Perichaena孢菌，P. corticalis，P.扁，绒泡apiculosporum，pH值。compressum，和pH值。didermoides是最常见的物种，每个物种至少有10条记录。尽管在研究期间对纤维状粘菌的科学生产有所增加，但致力于该组的研究人员却很少，机构间的合作可以得到改善。据观察，大多数作者只发表了一份出版物，声称自己不是该组的专家，而且热带丝状黏菌菌素显然已被研究不足。建议分子研究中的主题网络和方法学标准化可以增加和改进对纤维状粘菌的研究。我们着重指出，对纤维状粘菌的研究感兴趣的研究人员之间机构间合作的重要性，一旦许多研究人员对这些技术的访问受到限制，
