Lichen vermicularis Sw,, Meth. Musc.: 37, 1781
Synonyms: Thamnolia subuliformis (Ehrh.) W.L. Culb.; Thamnolia subvermicularis Asahina; Thamnolia vermicularis var. subuliformis (Ehrh.) Schaer.
Description: Thallus fruticose, pure white, remaining white in the herbarium, erect or decumbent, often forming tufts. Thallus units 1-2(-3) mm thick (rarely to 8 mm), worm-like, usually to 5 (rarely to 10) cm tall, more or less cylindrical, with pointed apices, smooth, non squamulose, simple or rarely sparingly branched in upper part. Cortex of longitudinally arranged hyphae; medulla thin, soon becoming hollow. Apothecia not known. Pycnidia poorly evident, immersed, initially covered by cortical tissue, flask-shaped to broadly globose, the wall colourless throughout, uni- or rarely bilocular, densely filled with long, parallel conidiophores comprising erect chains of intercalary conidiogenous cells with bayonet-like processes near the upper cell septum. Conidia bacilliform, slightly tapering at one end, 3-5 x 1-2 µm. Photobiont chlorococcoid. Spot tests: K+ yellowish, C-, KC-, P+ yellow, UV+ yellowish white. Chemistry: baeomycesic and squamatic acids.
