Blastodesmia is a monotypic fungal genus in the family Pyrenulaceae.[2] It contains the single species Blastodesmia nitida,[3] a corticolous (bark-dwelling) crustose lichen found in Europe. Both the genus and the species were described in 1852 by the Italian botanist Abramo Bartolommeo Massalongo.[4] Historically, two other species have been included in the genus, but are currently not accepted by Species Fungorum:[3]

  • Blastodesmia albonigra Zahlbr. (1927)[5]
  • Blastodesmia lactea A.Massal. (1852)[4]
Blastodesmia
Blastodesmia nitida; the black structures are perithecia (fruiting bodies)

Characteristics of genus Blastodesmia include paraphyses in the hamathecium, transversely septate ascospores that are grey to brown in colour, and pyrenocarp-type ascomata with carbonized ascoma walls. The ascospores are mostly 37–47 μm long and have a constriction at the septa.[6]
