Mycologia 6: 14 (1914)

Lamprospora maireana, apothecium Lamprospora maireana, ascospores
1: Lamprospora maireana, apothecium with shoots of Archidum alternifolium, Germany, Thuringia leg. Jan Eckstein 2013-11-03 2: Lamprospora maireana, ascospores in water on the left side and stained with lactophenol-cotton-blue on the right side, Germany, Thuringia leg. Jan Eckstein 2013-11-03
Apothecia: 0.3-4.0 mm in diameter with conspicuous membranaceous margin, hymenium yellowish-orange, orange or red
Asci: (280-)315-370 x 20-27(-36) µm, 8-spored, spores uniseriate
Ascospores: globose, inclusive ornamentation 19-24(-25) µm, exclusive ornamentation 15-20 µm in diameter, ornamentation consisting of rounded tubercles 3-6 µm wide and (1-)2-3(-5) µm high, partly confluent, with internal guttules therefore appearing "foamy"
Host: Archidium alternifolium, possibly also Fossombronia spec.
Habitat: on damp soil
Distribution: very rare in Germany (BY, TH) also known from Algeria, Australia, Canary Islands, Finland, France, The Netherlands, Norway, Portugal, Spain, United States
