Am. Midl. Nat., 77: 212, 1967. Basionym: Clavaria mucida Pers. - Comm. Fung. Clav.: 55, 1797.
Synonyms: Lentaria mucida (Pers.) Corner; Stichoclavaria mucida (Pers.) Paechn.
Distribution: N - Frl (Ravera & al. 2019b), Ven (Onofri & al. 2013), TAA (CLU 10971), Emil (Bernicchia & al. 1981, Fariselli & al. 2020).
Description: Thallus crustose, episubstratic, forming a soft, gelatinous (when wet), green to grey-green, 0.5-1 mm thick film made of minute granules consisting of clumps of algal cells incompletely surrounded by hyphae. Basidiocarps not lichenized, ephemeral (summer and autumn), cylindrical to club-shaped, 3-15(-20) mm tall, 0.2-0.5(-1) mm wide, creamy white, geotropically oriented, the apices pointed or slightly forked, the upper fertile part sometimes yellowish brown at maturity, the base slightly cottony, with a simple monomitic hyphal system, the hyphal septa with clamps, a dense subhymenium, and a thickening hymenium. Basidia clavate, with (4-)6 sterigmata. Basidiospores ellipsoid to slightly cylindrical, hyaline and smooth-walled, with (1-)2 oil droplets, (4.5-)5.5-6.5(-8) x 2-3.5 µm, I-. Photobiont chlorococcoid. Spot tests: all negative. Chemistry: thallus without lichen substances.Note: on decaying wood (logs, stumps) in pristine, humid montane forests; perhaps overlooked by lichenologists, but certainly very rare in Italy.
