一个新的棒形地衣化担子菌--喜藻枝棒菌。et sp. nov.，根据形态学观察和分子系统学分析，描述了日本的一个新种。虽然子实体是分散在身份不明的衰老bratelites生长在潮湿的岩石表面，菌丝不与bratelites细胞。相反，我们证实，菌丝松散包围的球形藻细胞存在于表面上的薄壳藻，形成一个未分化的叶状体。透射电子显微镜观察表明，该菌具有蛋白核样结构。B.与Multiclavula属地衣化种相似，但新种与Multiclavula属地衣化种的区别在于它不形成球状或珠芽状的叶状体。核核糖体RNA基因大亚基的分子序列数据表明，该物种被放置在一个新的谱系在Cantharellales，显然独立于genusMulticlavula。一个多孢子分离物B.成功地建立了嗜藻性菌株Phycophilia，并对其培养特征进行了简要描述。
A new clavarioid, lichenized basidiomycete,Bryoclavula phycophilagen. et sp. nov., is described from Japan based on morphological observations and molecular phylogenetic analyses. Although the fruiting bodies were dispersed on unidentified senescent bryophytes growing on a moist rock surface, the hyphae were not associated with the bryophyte cells. Instead, we confirmed that the hyphae loosely surrounded spherical algal cells present on the surface of bryophytes to form an undifferentiated thallus. The observations by transmission electron microscopy revealed that the alga had a pyrenoid. Morphological characters ofB. phycophilawere similar to those of lichenized species in the genusMulticlavula, but the new species differs from the latter in that it does not form a globular or bulbil-like thallus. Molecular sequence data of the large subunit of the nuclear ribosomal RNA gene showed that the species was placed in a new lineage in the order Cantharellales, clearly independent from the genusMulticlavula. A multispore isolate ofB. phycophilawas successfully established and the brief cultural characteristics are described.
