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), Lig (GE 151). 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, up to several cm wide patches (sometimes 1 dm or more), dull, pale lime-green, entirely composed of a very lax mass of thin-walled, hyaline, anastomosing, 2-3.5 µm thick hyphae with numerous septa, without true soredia-like granules. The hyphae are mainly erect, and bear laterally, in their distal parts, shrub-like clusters of 1-3 algal cells which are up to 15(-20) µm wide, in a form resembling a bunch of grape, not completely enclosed by hyphae. Medulla not evident. Photobiont chlorococcoid, the algal cells mostly spherical, single or forming short filaments of no more than 3 cells, 2.5-6(-10) µm thick, each cell with a nucleus and a parietal cup-shaped chloroplast with lobes, filling more than half of the cell periphery. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: lesdainin (6α-acetoxyhopan-22-ol), and a range of unidentified terpenoids (mostly in traces).

Note: on limestone, calcareous sandstone, basic siliceous rocks (e.g. basalt, lava), epilithic mosses and soil, sometimes on walls, especially in fissures, in shaded 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 leprarioid species.

Growth form: Leprose

Substrata: rocks, soil, terricolous mosses, and plant debris

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
