根据形态特征、岩石上独特的栖息地以及核糖体DNA内部转录间隔区序列的分子系统发育分析结果，将其描述为一新种。松材线虫的子实体散布在潮湿的岩石表面，有大量的地衣状小球体。球状菌体是由几个绿色藻类光生物细胞组成的，细胞内有类蛋白，周围环绕着真菌菌丝。系统发育分析表明，其隶属于多棒菌群。在水琼脂上萌发的担孢子，并提供了菌落形态的简要描述。Multiclavula RH Petersen(Cantharellales，担子菌门)属的特征是单枝或分枝的小棒状子实体，通常与藻类、苔藓或据称的黏菌有关(Petersen，1967)。在Multiclavula中，目前已发现12种：M.Clara(Berk.和MA Curtis)RH Petersen、M.Constans(Coker)RH Petersen、M.coronilla(GW Martin)RH Petersen、模式种M.corynoides(Peck)RH Petersen、M.delicata(Fr.)Rh Petersen、哈斯杜拉(M.hastula(Corner)RH Petersen)、鱼腥藻M.ichhyiformis Nelsen、L(M.Umana)、Trest&Will-Wolf、M.Mucida(Pers.)Rh Petersen、波戈纳特支原体(M.pogonati(Coker)RH Petersen)、
Multiclavula petricola is described as a new species based on morphological characters, its unique habitat on rocks, and the result of molecular phylogenetic analyses of the sequence of internal transcribed spacer of the nuclear ribosomal DNA. The fruiting bodies of M. petricola were dispersed on wet rock surface with numerous lichenized globules. The globular thallus was organized by several green algal photobiont cells with pyrenoids surrounded by mycobiont hyphae. The phylogenetic analyses indicated that its affiliation was in Multiclavula. The basidiospores of M. petricola germinated on water agar, and the brief descriptions of the colony morphology are also provided.© 2020 The Mycological Society of Japan. Published by Elsevier BV All rights reserved.The genus Multiclavula RH Petersen (Cantharellales, Basidiomycota) is characterized by simple or branched small clavarioid fruiting bodies usually associated with algae, mosses, or allegedly slime molds (Petersen, 1967). In Multiclavula, 12 species are currently recognized: M. clara (Berk. & MA Curtis) RH Petersen, M. constans (Coker) RH Petersen, M. coronilla (GW Martin) RH Petersen, the type species M. corynoides (Peck) RH Petersen, M. delicata (Fr.)
