Strangospora microhaema (Norman) R.A. Anderson

Bryologist, 78: 55, 1975. Basionym: Biatorella microhaema Norman in Th. Fr. - Bot. Not.: 99, 1865.

Synonyms:

Distribution: N - TAA (Nascimbene & al. 2007b). C - Mol (Caporale & al. 2008, Paoli & al. 2011), Sar (Rizzi & al. 2011, Di Nuzzo & al. 2022).

Description: Thallus crustose, granulose, endosubstratic or thinly episubstratic and developed only around the apothecia, generally inconspicuous, pale green-grey or grey. Apothecia biatorine, scarlet red to coral-red, 0.05-0.2(-0.3) mm across, with a strongly convex disc, without a distinct margin. Proper exciple poorly developed, K-; epithecium bright golden yellow, 10-20 µm thick, K-; hymenium golden yellow in parts, (60-)70-85(-95) µm high, I+ blue; paraphyses 1(-1.5) µm thick, richly branched and anastomosing, not thickened at apex; hypothecium colourless to pale yellow, 25-50 µm thick, Asci 50-100-spored, broadly clavate, thickened in upper part, without a gelatinous outer layer, the wall and well-developed apical dome strongly K/I+ blue. Ascospores 1-celled, hyaline to orange, globose, (3.5-)4-4.5 µm wide. Photobiont chlorococcoid, with ellipsoid cells. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a cool-temperate to boreal-montane, perhaps circumpolar, very rare species of more or less acid bark and lignum. It is included in the Italian red list of epiphytic lichens as “Vulnerable” (Nascimbene & al. 2013c).
