These organisms are widely occurring in marine and freshwater habitats, mostly infecting filamentous green algae. Presently, all species are only known from their morphology and descriptive life cycle traits. None of the seven species classified in <i>Sirolpidium,</i> including the type species, <i>S. bryopsidis,</i> has been rediscovered and studied for their molecular phylogeny, so far. Originally, the genus was established to accommodate all parasites of filamentous marine green algae. In the past few decades, however, <i>Sirolpidium</i> has undergone multiple taxonomic revisions and several species parasitic in other host groups were added to the genus. While the phylogeny of the marine rhodophyte- and phaeophyte-infecting genera <i>Pontisma</i> and <i>Eurychasma</i>, respectively, has only been resolved recently, the taxonomic placement of the chlorophyte-infecting genus <i>Sirolpidium</i> remained unresolved. In the present study, we report the phylogenetic placement of <i>Sirolpidium bryopsidis</i> infecting the filamentous marine green algae <i>Capsosiphon fulvescens</i> sampled from Skagaströnd in Northwest Iceland. Phylogenetic reconstructions revealed that <i>S. bryopsidis</i> is either conspecific or at least very closely related to the type species of <i>Pontisma</i>, <i>Po. lagenidioides</i>. Consequently, the type species of genus <i>Sirolpidium</i>, <i>S. bryopsidis</i>, is reclassified to <i>Pontisma</i>. Further infection trials are needed to determine if <i>Po. bryopsidis</i> and <i>Po. lagenidioides</i> are conspecific or closely related. In either case, the apparently recent host jump from red to green algae is remarkable, as it opens the possibility for radiation in a largely divergent eukaryotic lineage. <b>Citation:</b> Buaya AT, Scholz B, Thines M (2021). <i>Sirolpidium bryopsidis</i>, a parasite of green algae, is probably conspecific with <i>Pontisma lagenidioides</i>, a parasite of red algae. <i>Fungal Systematics and Evolution</i> <b>7:</b> 223-231. doi: 10.3114/fuse.2021.07.11.</p>","PeriodicalId":73121,"journal":{"name":"Fungal systematics and evolution","volume":"7 ","pages":"223-231"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/6e/1b/fuse-2021-7-11.PMC8165961.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39024004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Until recently most <i>Elaphomyces</i> specimens in North America were assigned names of European taxa due to lack of specialists working on this group and difficulty of using pre-modern species descriptions. It has recently been discovered that North America has a rich diversity of <i>Elaphomyces</i> species far beyond the four <i>Elaphomyces</i> species described from North America prior to 2012. We describe eight new <i>Elaphomyces</i> species (<i>E. dalemurphyi, E. dunlapii, E. holtsii</i>, <i>E. lougehrigii</i>, <i>E. miketroutii</i>, <i>E. roody</i>i, <i>E. stevemilleri</i> and <i>E. wazhazhensis</i>) of eastern North America that were collected in habitats from Quebec, Canada south to Florida, USA, west to Texas and Iowa. The ranges of these species vary and with continued sampling may prove to be larger than we have established. Castellano has studied authentic material of all European <i>Elaphomyces</i> species published through 2016 and it is interesting to note that many <i>Elaphomyces</i> species from eastern North America have morphological similarities but with distinct morphological differences to a number of European <i>Elaphomyces</i> species. <b>Citation:</b> Castellano MA, Crabtree CD, Mitchell D, Healy RA (2020).
