Reichlingia leopoldii Diederich & Scheid.

Bull. Soc. Nat. Luxemb., 97: 5, 1996.

Synonyms:

Distribution: N - Lomb (Brackel 2010, 2016).

Description: Thallus crustose-subleprose, episubstratic, grey-green in marginal parts, brown in central parts, entirely granulose, up to 2 mm thick, rather felty, usually forming large patches, sometimes delimited by a pale to brownish prothallus. Granules 200-300 µm across, developing on a conspicuous, purplish brown hypothallus, soon disintegrating into 30-50 µm wide soredia (often gathered into larger consoredia), with few or no projecting hyphae. Apothecia absent. Conidia produced in central parts of thallus, in reddish to brownish, irregular, 0.1-0.4 mm wide, sporodochia-like structures which start as separate dark dots and later coalesce covering larger surfaces. Conidiophores dark brown, with a thick, warted wall. Conidia brown, 17-35 µm long, mostly 3-septate and constricted at septa, the individual cells 4-6 x 3.5-5.5 µm, with a strongly warted wall. Photobiont trentepohlioid. Spot tests: thallus K-, C-, KC- or KC+ faintly reddish, P-, UV-. Chemistry: 2’-0-methylperlatolic acid.

Note: originally described as a lichenicolous fungus, this species is now recognised as a lichenised hyphomycete (see e.g. Aptroot 2010). It grows under overhangs of siliceous rocks, more rarely on the bark of old oaks in sheltered situations, mostly in the submediterranean belt.
