Botryolepraria lesdainii (Hue) Canals, Hern.-Mar., Gómez-Bolea & Llimona

Lichenologist, 29: 340, 1997. Basionym: Crocynia lesdainii Hue - Bull. Soc. Bot. France, 71: 350, 1924.
Synonyms: Crocynia grevilleana B. de Lesd.; Lepraria lesdainii (Hue) R.C. Harris
Distribution: N - VG (Baruffo & al. 2006), Frl (Baruffo & al. 2006), Ven (Thor & Nascimbene 2007), Lomb (Baruffo & al. 2006), Emil (Baruffo & al. 2006, Fariselli & al. 2020). C - Tosc (Baruffo & al. 2006), Sar (Kümmerling & Leuckert 1993, Baruffo & al. 2006). S - Si (Kümmerling & Leuckert 1993, Grillo 1998, Grillo & al. 2001, Grillo & Caniglia 2004, Baruffo & al. 2006).
Description: Thallus leprose, byssaceous, cottony, forming 1-3 mm thick patches to several cm wide (sometimes a dm or more), dull, pale lime-green, composed of very lax mass of thin-walled, hyaline, anastomosing 2-3.5 µm thick hyphae with numerous septa. The hyphae are mainly erect, and bear laterally, in their distal parts, clusters of 1-3 algal cells to 15(-20) µm diam. Medulla not evident. Ascocarps and pycnidia not known. Photobiont chlorococcoid, the algal cells mostly spherical, single or forming short filaments no more than 3 cells long, 2•5–6(-10) µm diam; each cell with a nucleus and a parietal cup-shaped chloroplast with lobes, filling more than half of the cell periphery. Spot tests: all negative. Chemistry: lesdainin, and a range of unidentified terpenoids (mostly in traces).
Note: on limestone, calcareous sandstone, epilithic mosses and soil, sometimes on walls, especially in fissures, in sites protected from rain, certainly much more common throughout Italy below the subalpine belt. According to Baruffo & al. (2006) this is the most shade-loving among all species of Lepraria s.lat.
Growth form: Leprose
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
In underhangs rarely wetted by rain
