Description

Cetrelia chicitae (W. L. Culb.) W. L. Culb. & C. F. Culb.

Description.

Thallus foliose, heteromerous, dorsiventral, loosely attached, forming wavy, wide-spreading, usually orbicular, wide rosettes. Upper surface glaucous-grey, lower surface black in the central part to brown at the lobe edges. Lobes broad and round, up to 20 mm wide, with raised margins. Pseudocyphellae punctiform to irregularly-shaped on upper surface, which are rather large and usually not raised, also developed in the older, central parts of thallus; pseudocyphellae on lower surface not developed, or appearing as very small white dots. Soralia primarily marginal on strongly twisted lobes, giving the lobe-ends a somewhat nibbled appearance, usually smooth, with coarse soredia (35–55 µm). Lower surface rather regularly ridged, with scattered, simple, black rhizines and a rhizine-free zone along the margin. Never found fertile in Italy.

Chemistry.

Cortex with atranorin (sometimes in low concentrations); medulla with alectoronic, α-collatolic and physodic acids.

Distribution in Italy.

Central-eastern Alps (16 specimens from 5 sites): Friuli Venezia Giulia (4 specimens from 2 sites), Veneto (2 specimens from 1 sites), Trentino Alto Adige (1 specimen from 1 site), Lombardia (9 specimens from 1 site). Fig. 2.

Habitat.

Beech, coniferous or mixed beech-coniferous forests in the montane belt (870–1195 m a. s. l.), moist due to frequent rainfall and / or fog, usually near streams.

Phorophytes.

Abies alba, Fagus sylvati ca.

Literature.

Confirmed citations: Friuli Venezia Giulia: Nascimbene et al. (2021); Veneto: Nascimbene et al. (2021).

Remarks.

This is the rarest Cetrelia species in Italy, which is in accord with the data from the rest of Europe (Obermayer and Mayrhofer 2007; Harrold et al. 2009). It is instead one of the most widespread species in other areas, e. g., North America (Howland and Lendemer 2023) and India (Mishra and Upreti 2015).
