NOVOTNÝ D. (2010): First record of Ceratocystis laricicola (Ascomycota, Ceratocystidaceae) in the Czech Republic.   [Ascomycota, ophiostomatoid fungi, Larix decidua, distribution, Ips cembra]  Czech Mycology 62(1): 59-65   (published: 15th February, 2011)
  abstract   During the study of large larch bark beetle (Ips cembrae) mycobiota, the species Ceratocystis laricicola was isolated. It was detected in galleries and on the surface of the beetle body. This fungus is a well-known larch pathogen and this observation is the first report of its occurrence from the Czech Republic.

JANKOWIAK R., ROSSA R., MIŚTA K. (2007): Survey of fungal species vectored by Ips cembrae to European larch trees in Raciborskie forests (Poland).   [ophiostomatoid fungi, Ips cembrae, Larix decidua, fungi associated with bark beetles]  Czech Mycology 59(2): 227-239   (published: 28th December, 2007)
  abstract   The species composition of fungi associated with Ips cembrae was studied in the Raciborskie forests, Poland. The fungi were isolated from overwintered adults, larvae, new adults and from galleries at various stages of development. The results showed that there was a great diversity of fungi associated with this insect. We isolated 2877 cultures, including 61 species. The most important group of fungi were ophiostomatoid species. From these, Ceratocystis laricicola, Ophiostoma brunneo-ciliatum and Graphium laricis were commonly detected, whereas eight other species occurred less frequently or sporadically. Ophiostoma ips is documented here as a new associate of I. cembrae. Ceratocystis laricicola was shown to be the primary invader occurring most frequently at early stages of brood development, particularly in the sapwood. Ophiostoma brunneo-ciliatum and G. laricis were secondary invaders following C. laricicola. In the later stages of brood development other ophiostomatoid fungi appeared.

NOVOTNÝ D., JANKOVSKÝ L. (2005): Notes on mycobiota associated with Ips typographus from the Šumava Mts. (Czech Republic).   [Piceaabies, ophiostomatoidfungi, bark beetles]  Czech Mycology 57(1-2): 91-96   (published: 31st August, 2005)
  abstract   In 1999 and 2000, stem samples of Norway spruce (Picea abies) infested by bark beetle (Ips typographus) from one spruce stand localitya ffected by massive infestation by Ips typographus in the central part of the Šumava mountains were taken.The mycobiota of 20 adults was studied. Eighteen species of microscopic fungi were recorded. Yeasts and ophiostomatoid fungi were detected most frequently.

NOVOTNÝ D., ŠRŮTKA P. (2004): Ophiostoma stenoceras and O. grandicarpum (Ophiostomatales), first records in the Czech Republic.   [ophiostomatoid fungi, distribution, oak, roots, bark, Ceratocystis, Quercus petraea, Quercus robur]  Czech Mycology 56(1-2): 19-32   (published: 12th August, 2004)
  abstract   Two species of ophiostomatoid fungi were observed in oaks. Ophiostoma stenoceras was isolated during a study of endophytic mycobiota of the roots and seedlings of a sessile oak (Quercus petraea). Ophiostoma grandicarpum was recorded in the stem of a pedunculate oak (Q. robur). These fungi have not yet been reported from the Czech Republic. The knowledge on the occurrence of ophiostomatoid fungi in the Czech Republic is reviewed.

KUBÁTOVÁ A., KOLAŘÍK M., PRÁŠIL K., NOVOTNÝ D. (2004): Bark beetles and their galleries: well-known niches for little known fungi on the example of Geosmithia.   [microfungi, Geosmithia, Scolytidae, ophiostomatoid fungi, yeasts]  Czech Mycology 56(1-2): 1-18   (published: 12th August, 2004)
  abstract   The oak bark beetle (Scolytus intricatus, Scolytidae, Coleoptera) was studied during the years 1997-2003 with respect to the occurrence of microscopic fungi on the surface of its body. Samples were collected in eight localities in the Czech and Slovak Republics. The investigation was focused on all different stages of the beetle’s life cycle: eggs, larvae, adults be for e emergence, adults in generation and maturation feeding (nearly 600 samples), and also on galleries (400 samples). The most frequent fungi associated with S. intricatus were yeasts, Geosmithia spp. and Penicillium spp. Ophiostomatoid fungi were isolated, too. Great attention was paid to the occurrence of Geosmithia spp., which were so far recorded rarely. They were frequently found in all stages of the life cycle of Scolytus intricatus, except for males in maturation feeding. The ecology of Geosmithia spp. in feedings of phloem inhabiting insects is discussed for their negative cellulase production and the ecology of associated insect species. Trees infested with Scolytus intricatus represent a major and still little explored niche of Geosmithia spp.
