... Th e infection aff ects mostly the rhizoids (e.g. Benkert 2006, Eckstein and Eckstein 2009), rarely rhizoid tubers (Benkert 1998), stems, and leaves (Benkert andBrouwer 2004) as well as infrequently the protonema (Eckstein and Eckstein 2013, Döbbeler and Facher 2014, Vega et al. 2015). Because of their diffi cult perceptibility, most of bryophilous Pezizales are underrecorded worldwide and they have so far not been detected in many countries (Eckstein 2016). ...
New occurrences, macroscopic and microscopic features, and ecological aspects of Octospora erzbergeri, an obligate bryophilous ascomycete, parasitising exclusively on the moss Pseudoleskeella nervosa are discussed. Furthermore, illustrations regarding circumstances of Hungarian occurrences, microscopic characters including spore ornamentation and infection structure as well as illustrations of the possibly co-occurring species are provided. Apart from the SEM pictures of spores, each photographic illustration of the species is published here for the first time.
Some noteworthy findings of bryoparasitic Pezizales from the federal states of Bavaria, Hamburg, Lower Saxony, Saxony, Saxony-Anhalt and Thuringia are reported. The description for each species contains relevant macroscopic and microscopic characters, host bryophyte relationships and habitat preferences. New federal state records are provided for Lamprospora dicranellae, L. tuberculata and Octospora bridei in Lower Saxony, for Neottiella vivida in Thuringia and for N. albocincta first records for the federal states of Bavaria, Hamburg, Saxony as well as Thuringia are reported. The hitherto unknown parasite host relationships of L. dicranellae and Ditrichum heteromallum as well as of O. coccinea and Acaulon muticum are being described.
Lamprospora hispanica and L. tuberculatella, two rarely collected bryoparasitic Pezizales, are reported as new to Germany. The German finds are described morphologically and details of habitat preferences ands well as observation of host species are reported. The observations from the German finds are compared to the relevant published data. Lamprospora hispanica was found to be parasitic to the mosses Aloina aloides and Trichostomum crispulum. The parasite-host relationship to the latter species was hitherto unknown. Weissia spec. was observed as host of L. tuberculatella. Both species of bryoparasitic Pezizales occur in Germany mainly at warm, sun-exposed sites on small patches of disturbed soil in dry grassland. Since such habitats are endangered throughout Germany due to land use changes, it is assumed that the two species are also endangered.
Taxonomy of some European species of Ephemerum is reviewed. As in several other recent studies, E. minutissimum Lindb. is regarded as a distinct species from E. serratum (Hedw.) Hampe; it is recorded from N. America (by the newly designated lectotype and other specimens) and Turkey, in addition to Europe. E. serratum var. angustifolium Bruch & Schimp. may be a synonym of E. minutissimum; the costate forms E. serratum var. praecox A.W.H.Walther & Molendo and E. intermedium Mitt. in Braithw. are treated as synonyms of E. serratum s.str. Type specimens of E. stellatum H.Philib. are described, a lectotype is designated and it is placed as a synonym of E. serratum s.str. E. hibernicum Holyoak & V.S.Bryan is regarded as a synonym of E. rutheanum Schimp. in Ruthe. The latter is shown to be a rare, European endemic taxon with modern records from Ireland, S. Wales, Germany and The Netherlands, and old records from France and W. Poland; a lectotype is designated. Forms intermediate between E. sessile (Bruch.) Müll.Hal. and the N. American E. crassinervium (Schwägr.) Hampe occur in several countries in W. Europe, some of them indistinguishable from some of the American plants; forms intermediate between E. sessile and E. rutheanum are recorded from S. Portugal and (rarely) Ireland. Differences between E. crassinervium, E. sessile and E. rutheanum in characters of leaves, tubers and capsules are shown to be slight, with considerable overlap. Hence all three taxa are treated as subspecies of E. crassinervium. A revised key to European Ephemerum and Micromitrium is presented.
Abstract: Lamprospora arvensis (Velen.) Svrček is reported from Germany and Portugal for the first time. A description and illustrations of both macroscopic and microscopic characters are provided. The German report on the bryophyte host Ceratodon purpureus (Hedw.) Brid. is compared to the Portuguese one on Pleuridium acuminatum Lindb., a moss which so far has not previously been identified as a host. Several morphological differences suggest the existence of two taxa in Europe. These differences are discussed and the distribution of Lamprospora arvensis in Europe is given.
Seit 1987 sind von Lamprospora maireana und L. tuberculatella vor allem aus Europa eine Anzahl neuer Funde bekannt geworden. Lamprospora maireana ist in Europa nun bekannt aus Deutschland, Finnland, Frankreich, den Niederlanden, Norwegen und Spanien, L. tuberculatella aus Frankreich, den Niederlanden, Portugal und Ungarn. Als Wirtsmoose konnten nachgewiesen werden Archidium alternifolium für L. maireana sowie Didymodon vinealis, Ephemerum megalosporum und Weissia controversa für L. tuberculatella. Es wird diskutiert, ob Lamprospora maireana und L. tuberculatella gut charakterisierte, einheitliche Arten sind, oder ob die taxonomisch und ökologisch sehr unterschiedlichen Wirtsmoose und teilweise auch geringe morphologische Unterschiede auf das Vorliegen von Komplexen von nahe verwandten Taxa hindeuten.

Variability and distribution of Lamprospora maireanaSeaver and L. tuberculatellaSeaver
Since 1987 a number of new collections of Lamprospora maireana and L. tuberculatella have been found in Europe. Within Europe Lamprospora maireana now is known from Finland, France, Germany, the Netherlands, Norway, and Spain, Lamprospora tuberculatella from France, Hungary, the Netherlands, and Portugal. Proved host-mosses are Archidium alternifolium in the case of Lamprospora maireana and Didymodon vinealis, Ephemerum megalosporum, and Weissiacontroversa in the case of L. tuberculatella. It is discussed whether Lamprosporamaireana and L. tuberculatella are homogenous, well characterized species. The taxonomically and ecologically very different host-mosses as well as partly slight morphological differences possibly could indicate, that Lamprospora maireana and L.tuberculatella may be complexes of closely related taxa.
