Saelania glaucescens is recognizable for the striking, glaucous green colour of the leaves, which is caused by a covering of waxy rods on the leaf surface. It is an arctic-montane species, growing on soil in the crevices of basic rocks or in sheltered niches on calcareous crags. It is rare in southern Italy, and in Calabria it was previously reported only from Gioia Tauro (

Schistostega pennata is a peculiar moss species well known for its luminescent appearance when growing in very dark places, due to the light reflective properties of the convex cells of its persistent protonema.

Lentinellus ursinus (Fr.) Kühner (Auriscalpiaceae)
+ CAL: Botanical Garden, University of Calabria, Rende (Cosenza), on a fallen decaying oak branch under a downy oak (Quercus pubescens Willd.) tree at the edge of a mixed deciduous oak coppice stand, Q. pubescens as prevailing species (UTM WGS84: 33S 605916.435729), 200 m, 25 October 2021, G. Sicoli, A.B. De Giuseppe, N.G. Passalacqua (CLU F320). – Species new for the flora of Calabria.
A fasciculate cluster of five basidiomata referable to the genus Lentinellus Karst. was detected on a partially decayed branch fallen from an oak tree (Q. pubescens) standing over it. Pilei were spathulate, less than 5 cm wide, and laterally attached to the wood via a very rudimentary stipe. The above side of the pileus was felty and dull, brown-to-bay and slightly hirsute in the centre, paler and smoother towards an involute margin. The downside showed crowded and irregularly toothed gills producing hyaline, subglobose, finely ornamented and strongly amyloid spores, measuring 3.0–4.5 × 2.5–3.5 µm. The above characteristics led to identify this saprotrophic fungus as L. ursinus (

De Giuseppe, N.G. Passalacqua, G. Sicoli (CLU F321). – Species new for the flora of Calabria.
A dozen sparse pileate and stipitate basidiomata were detected on the ground in a 10m2-wide grassy clearing between a downy oak tree (Q. pubescens) and a holm oak tree (Q. ilex). Pilei were infundibuliform, vividly brownish, striate at margin and less than 3 cm wide. Stipes were slender, sometimes flexuose, glabrous and more or less concolorous. The hymenophore consisted of pale brown, rather distant and decurrent gills producing hyaline, amygdaloid and smooth spores, measuring 7.5–8.5 × 4.5–5.0 µm. Cystidia were not observed. The above characteristics led to recognise this fungus as the saprotroph Omphalina pyxidata (

+ CAL: Botanical Garden, University of Calabria, Rende (Cosenza) (UTM WGS84: 33S 605966. 4357130), on the ground under the crown of an Atlas cedar tree [Cedrus atlantica (Endl.) Manetti ex Carrière], 220 m, 15 November 2021, N.G. Passalacqua, A.B. De Giuseppe, G. Sicoli (CLU F322). – Species new for the flora of Calabria.
A group of five small, gregarious collybioid basidiomata were observed on the ground among the dead needles of a planted tree of Cedrus atlantica. The youngest pilei were convex and narrowly involute at the edge, the most mature were applanate, slightly depressed, matt, smooth to wrinked, dark grey-brown in the centre, light greenish at the edge, and 1.5–3.5cm wide. The lower side of the pileus showed rather distant and emarginated gills, which were green-yellowish and were supported by a concolorous, slender, tapering, flexuose and fibrillose stipe. Spores were amygdaliform, smooth, hyaline, and 9–11 × 5–7µm-sized. Based on the above characters and ecology, this fungus had first been described as Callistosporium olivascens (Boud.) Bon, more specifically as C. olivascens var. aerinum (Quél.) Bon, but its current name is Xerophorus olivascens (

Agonimia repleta is characterized by a granular-verrucose to minutely squamulose thallus with black, smaller, roughened pyriform perithecia. It is widespread in Europe mainly on bark among mosses, often in riparian habitats. In temperate forests, it is common on bark at bases of deciduous trees, especially beech.
