1: Lamprospora tuberculata, apothecia with Pleuridium subulatum |
2: Lamprospora tuberculata, spores in water (left) and spores stained with lactophenol-cotton-blue (right) |
Apothecia: 1-2 mm in diameter with broad membranaceous margin, hymenium orange
Asci: 320-375 x 20-25 µm, 8-spored, spores uniseriate
Ascospores: globose, inclusive ornamentation (13-)15-18(-20) µm in diameter, ornamentation consisting of rounded warts and tubercles of very uneven sizes, large ones (2-)3-6(-8) µm broad, small ones 1-2 µm broad
Host: Pleuridium acuminatum, Pleuridium subulatum
Habitat: on soil
Distribution: Australia, Austria, Czech Republic, France, Germany (rare, BW, BY, BB, NI), Hungary, The Netherlands, Norway, Slovakia, Spain, Switzerland, United States
Note: Vega et al. 2021b: 'Contrary to reports by Benkert (1987)
and Wang & Kimbrough (1992) we observed Pleuridium subulatum as the host. Astonishingly, a few
plants have large irregular shaped rhizoidal tubers which had
not been reported for P. subulatum in North America but are
known from Scandinavia (Jensen 1939; Hallingback 2006).
Our spore measurements are 15-17 µm diam. with larger
tubercles 2-4 µm wide and up to 2.5 µm high. Whereas the
host is the same in North American and European collections,
there are differences in the spore ornamentation. The
tubercles in Seaver's samples are more hemispherical and not
so irregularly shaped as in European collections examined in
this study or in those documented in Eckstein et al. (2014)
and Egertova et al. (2015). Furthermore, one of the collections
presented here as L. tuberculata agg. (ZT Myc 61081)
and the collection in Egertova et al. (2015) induce large
galls (60-125 µm in case of ZT Myc 61081) on the rhizoids
of the bryophyte host while no galls could be found in the
United States material. New collections of L. tuberculata from
Northern America are needed for DNA analysis to resolve
the question whether United States and European collections
of L. tuberculata represent the same taxon.'
