This has resulted in the discovery of 92 different species after a total of 180 visits to the locality. Change in the frequency of survey to approximately a weekly visit during the seasons from 2010 resulted in a large increase in species diversity, also of red-listed species. During these last 13 years of survey, the total number of species more than doubled, and the number of red-listed species more than tripled, which clearly shows the huge effect in changing the frequency of visits to a visit once a week during the season. The survey also clearly shows that the number of finds during a visit varies greatly from year to year and from week to week. In an optimal year for grassland fungi, around 70% of the species that grow there can be found in a weekly survey throughout the season, while a less good year gives a maximum of 40% finds. The survey also shows that the time of visit in a particular year is decisive for how many species are found in one visit. In an optimal year for grassland fungi, at the best possible match with time of survey, you can find up to 50% of the species growing there in one visit, but more likely it will be around 35%. It therefore shows very clearly that visits during the whole season is necessary to get hold on all fungi growing here. The survey also shows that many grassland fungi have very irregular fructification from one year to the other, which particularly applies to species within the genera Clavaria and Entoloma. Only ten species were found each year during the survey, most of which were waxcaps (Hygrocybe s.l.), while 14 species were only found in one of the years of survey. The time of fruiting also seems to have changed during the 20 years the survey has been ongoing. The week with the highest number of species recorded in 2021/22 is approximately 3-4 weeks later than it was in 2013/14. This is particularly clear for the genus Entoloma, which normally has an early and limited fruiting period.

Pretreatment of the virus with antibody and complement (C) resulted in a sixfold increase in the haemolysis. The viral haemolysin (HL) could be inactivated by heating the virus at 37 degrees C for 5 h. HL-inactivated virus became haemolytic again when pre-treated with antibody and C. This acquired haemolytic capacity corresponded to the enhanced haemolysis shown by intact virus. It is concluded that the enhanced haemolytic activity is due to a C-mediated indirect haemolysis and is not dependent on the fusion process. The possibility of cell damage in vivo from virus-antibody-C complexes is discussed.

I løpet av 2009 og 2010 er det gjort supplerende kartlegging i kulturlandskapet i fem av kommunene i Sunnhordland, og det er gjort en rekke nye funn av sopp i flere av lokalitetene som er undersøkt. Lokalitetene som er beskrevet i rapporten er av naturtypen naturbeitemark, som er gamle beitemarker med lang kontinuitet. Det betyr at de har hatt den samme driftsformen i generasjoner ved at området har vært beitet og at det ikke har vært foretatt gjødsling i særlig grad. Slike naturtyper blir mer og mer sjeldne, og naturbeitemark og slåtteenger blir i dag regnet som truete naturtyper. I de 10 lokalitetene som er beskrevet for Stord, Fitjar, Sveio og Tysnes er det gjort hele 83 nyfunn av sopp hvor 42 av funnene er rødlistearter, mange i høy truethetskategori. I alt 29 av disse funnene er nye rødlistearter for de kommunene der de er funnet (11 i Stord, 3 i Fitjar, 3 i Sveio og 12 i Tysnes), noe som er et svært høyt tall når en tenker at dette er områder som har vært undersøkt flere ganger tidligere. Tar en også med Bømlo, der andre har stått for hovedkartleggingen, er tallet på nye rødlistearter 45. Flere av artene som er funnet er sjeldne i landsmålestokk, og noen av dem representerer nye funn for Hordaland. I rapporten beskrives noen av de rikeste og mest verdifulle kulturlandskapene i Sunnhordland, sannsynligvis også i Hordaland, og det blir gitt en oversikt over det biologiske mangfoldet i de ulike lokalitetene. Det er også gjort en oppdatering over alle funn av rødlistearter i seks Sunnhordlandskommuner.

All together 71 different grassland fungi are known from the area including 32 species which are found on the Norwegian red list. The area has been investigated several times the last 11 years (2003-2013), and the last four years almost once a week in the season resulting in totally 80 visits. Every year some new species were found, but after the season had been expanded to a visit almost every week the number increased profoundly. The number of redlisted species was almost doubled from the year before. Even in 2013 six new species appeared, four of them redlisted. Among them was the very seldom Clavaria pullei. Only eleven species were retrieved each year, and these were mostly ordinary species. Nine species, most of them red listed, were found only once. Even after 11 years of investigation the number of species for some gro...

In this paper the earthtongues (Geoglossaceae) are presented and their ecology is discussed. Their distribution in Norway is briefly commented on. Before 1999 only eight species of earthtongues were known from the area and only 14 collections. Today about 300 collections of earthtongues have been made in 130 localities, representing more than 15 different species. Among these are many threatened and redlisted species in Norway like Geoglossum difforme, G. uliginosum, Microglossum olivaceum, M. atropurpureum and Trichoglossum walteri. The richest earth tongue localities also contain a very high number of other rare grasslandfungi. The geology in Sunnhordland is locally baserich, and the most species rich localities are found in the geological richest areas.

paper, Hovaneset in Stord municipality, South-
Western Norway, has been examined for grassland
fungi for 20 years, from 2003 until today
(2022). This has resulted in the discovery of
92 different species after a total of 180 visits
to the locality. Change in the frequency of
survey to approximately a weekly visit during
the seasons from 2010 resulted in a large
increase in species diversity, also of red-listed
species. During these last 13 years of survey,
the total number of species more than doubled,
and the number of red-listed species more
than tripled, which clearly shows the huge
effect in changing the frequency of visits to a
visit once a week during the season. The
survey also clearly shows that the number of
finds during a visit varies greatly from year
to year and from week to week. In an optimal
year for grassland fungi, around 70% of the
species that grow there can be found in a
weekly survey throughout the season, while
a less good year gives a maximum of 40%
finds. The survey also shows that the time of
visit in a particular year is decisive for how
many species are found in one visit. In an
optimal year for grassland fungi, at the best
possible match with time of survey, you can
find up to 50% of the species growing there
in one visit, but more likely it will be around
35%. It therefore shows very clearly that
visits during the whole season is necessary to
get hold on all fungi growing here.
The survey also shows that many grassland
fungi have very irregular fructification
from one year to the other, which particularly
applies to species within the genera Clavaria
and Entoloma. Only ten species were found
each year during the survey, most of which
were waxcaps (Hygrocybe s.l.), while 14
species were only found in one of the years
of survey. The time of fruiting also seems to
have changed during the 20 years the survey
has been ongoing. The week with the highest
number of species recorded in 2021/22 is
approximately 3-4 weeks later than it was in
2013/14. This is particularly clear for the
genus Entoloma, which normally has an early
