Remarks (internal):Serendipita vermifera was originally reported as a saprotrophic fungus in Germany (Oberwinkler, 1964), subsequently as an orchid endomycorrhizal fungus in Australia (Warcup & Talbot, 1967), also forming ectomycorrhiza with non-orchidaceous plants in Australia (Warcup, 1988), and again as a saprotrophic species in Great Britain (Roberts, 1993b). The original description specified occasional clamp connexions on the hyphae, but cultures of the species produced no such clamps (Warcup & Talbot, 1967; Warcup, 1988) nor were they seen in British collections (Roberts, 1993b).
The species was originally placed in the catch-all genus Sebacina Tul., but is not related to the generic type, S. incrustans (Pers.: Fr.) Tul.

Description:Serendipita vermifera (Oberw.) P. Roberts, Mycol. Res. 97: 474 (1993). Figures 62 & 63
Sebacina vermifera Oberw., Nova Hedw. 7: 495 (1964).
Exidiopsis vermifera (Oberw.) Woj., Grzyby 8: 100 (1977).
Teleomorph. Basidiome: normally not macroscopically visible; if visible, then effused, thin, ceraceous, pale grey to white. Hymenium: not formed; basidia occur singly or in small clusters on sparsely branched hyphae trailing over and through substrata. Hyphae: 'multinucleate (Williams & Thilo, 1989) 0.5-2(-4) µm wide, apparently without clamp connexions; hyaline and thin-walled. Septal pores: dolipores with continuous parenthesomes (Williams & Thilo, 1989). Basidia: 2-4 celled, globose to ellipsoid (Q = 1.0-1.3), 8.5-12 x 6.5-10 µm, normally arising singly on short side-branches or sub-basidial hyphal compartments at right angles to the main hyphae, then proliferating to form small clusters. Sterigmata: (1-)2-4, tubular, sinuous, up to 20 µm long, often producing subsidiary sterigmata and then appearing furcate or branched. Hyphidia: absent. Cystidia: absent. Basidiospores: elongated, vermiform, straight or slightly sinuous (Q = 14-28), 21-86 x 1.5-3 µm, producing secondary spores by replication.
Anamorph. The unnamed Rhizoctonia-like anamorph produces monilioid hyphae comprising chains of mostly subglobose compartments, 9-14 µm diam. (illustrated in Warcup & Talbot, 1967).
Habitat & ecology. Saprotrophic, orchid endomycorrhizal, and ectomycorrhizal.
Distribution. Australasia: Australia (Warcup & Talbot, 1967); Europe: Balearic Islands (K); British Isles (K); Denmark (Hauerslev, 1976); Germany (Oberwinkler, 1964).
Additional illustrations. Oberwinkler (1964); Hauerslev (1976); Roberts (1993b); Warcup & Talbot (1967).
