Arnium lanuginosum Nitschke [as ‘lanuginosa’], Bot. Ztg. 31: 450 (1873)

MycoBank number: MB 189013; Index Fungorum number: IF 189013; Facesoffungi number: FoF 10137;

Saprobic on wood. Sexual morph: Ascomata perithecial, superficial, globose to subglobose, tomentose. Asci 8-spored, unitunicate, cylindrical. Ascospores oval to ellipsoidal, dark brown, with gelatinous appendage at each end. Asexual morph: Undetermined (adapted from Nitschke 1873; Ellis and Everhart 1892).

Notes: Ellis and Everhart (1892) believed that Arnium lanug- inosum and Podospora brassicae were conspecific, and these species were synonymized under A. olerum (Lundqvist 1972) based on similar ellipsoidal ascospores with cylindrical gelati- nous appendages. In this study, A. olerum was transferred as C. olerum based on phylogenetic analysis (see notes for Cladorrhinum olerum). However, there is no molecular data for A. lanuginosum and we could not obtain any related specimens.
