嗜水喜担子 gen.等十一月（Aurulariales，s.l.）与无性型，CRUCELLA subtilis anam。将军等十一月，进行了描述。这种无性型是从阿拉巴马州[美国]的一条小溪中收集的腐烂叶子中分离出来的。在水中长时间孵育后，有性型在无性型的纯培养物中发育。该真菌产生具有钳连接的双核菌丝体。双核菌丝体形成的初级和次级隔膜简单，中心孔小。浸没后，耳状担子单个散布在菌丝垫中；它们是弯曲的，并且在每个担子节上具有无柄担子孢子簇。单核细胞的分生孢子发生细胞在产生单个分生孢子后变空并塌陷。有丝孢子（分生孢子）通常是四放射状的。在萌发过程中，分生孢子将其细胞质内容物排空到芽管中，并在分生孢子体内形成回缩隔膜。当在双重培养物中生长时，嗜水梭菌的菌丝与其他真菌的菌丝接触并盘绕，表明该物种可以是寄生的。
CAMPTOBASIDIUM hydrophilum gen. et sp. nov. (Auriculariales, s. l.) with an anamorph, CRUCELLA subtilis anam. gen. et sp. nov., are described. The anamorph was isolated from decaying leaves collected in a stream in Alabama [USA]. After prolonged incubation in water, the teleomorph developed in pure cultures of the anamorph. The fungus produces dikaryotic mycelium with clamp connections. Primary and secondary septa formed by the dikaryotic mycelium are simple with a small central pore. Auricularioid basidia are scattered singly in the mycelial mat after submergence; they are bent and bear clusters of sessile basidiospores on each basidial segment. Monoblastic conidiogenous cells become empty and collapsed after producing a single conidium. The mitospores (conidia) are typically tetraradiate. During germination, conidia empty their cytoplasmic contents into germ tubes and form retraction septa in the conidium body. When grown in dual culture, hyphae of C. hydrophilum make contact with and coil around the hyphae of the other fungi suggesting that the species can be parasitic.
