1: Lamprospora kristiansenii, apothecia between shoots of Ceratodon purpureus, Germany, Thuringia, Duderstadt, leg. J. Eckstein 2010-Oct-17 2: Lamprospora kristiansenii, ascospores in water, Norway, Asmaløy, leg. Roy Kristiansen 1988-Oct-18
Apothecia: 1-2.5 mm in diameter, with prominent membranaceous, dentate margin, hymenium orange to orange-red
Asci: 260-340 x 18-25 µm, 8-spored, uniseriate
Ascospores: globose, inclusive ornamentation 16-19 µm in diameter, exclusive ornamentation 14-16 µm in diameter, ornamentation consisting of ridges 0.8-1.2(-1.5) µm broad and 1 µm high forming an areolate, large-meshed reticulum of the Campylopodis-subtype with 3-5(6) meshes per diameter
Host: Ceratodon purpureus
Habitat: on nutrient-poor, sandy soil with Ceratodon purpureus
Distribution: Czech Republic (Janošík unpublished), Germany (TH), Norway
