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.

  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.

NOVOTNÝ D. (2003): A comparison of two methods for the study of microscopic fungi associated with oak roots.   [Quercus robur, oakdecline, Czech Republic, mycobiota, ophiostomatoid fungi]  Czech Mycology 55(1-2): 73-82   (published: 23rd July, 2003)
  abstract   Roots of four trees with symptoms of oak decline and roots of one healthy tree of Quercus robur were examined for the presence of fungi by using two methods (moist chambe rmethod and strong surface sterilisation method). Forty-five species were isolated in this project. Significant differences in composition of mycobiota based on the used method were detected. Fusarium solani, F. proliferatum, Sphaerostilbella aureonitens, Cylindrocarpon destructans, Pénicillium simplicissimum, P. purpurogenumvar. rubrisclerotium, Trichodermaviride, Ophiostomapiceae s.l. and Pénicillium glandicola were the most frequent fungi isolated by the moist chamber method. Cryptosporiopsis radicicola, dark sterile mycelium sp. 1, Cylindrocarpon destructans, ChaetomiuM globosum, Cylindrocarpon didymum, Pénicillium simplicissimum and Trichoderma koningii were dominant species observed by the method of strong surface sterilisation.

NOVOTNÝ D. (2002): Contribution to the knowledge of the mycoflora in roots of oaks with and without tracheomycotic symptoms.   [Quercus robur, Q. petraea, Q. rubra, oak decline, ophiostomatoid fungi, Penicillium, Czech Republic, Moravia]  Czech Mycology 53(3): 211-222   (published: 10th January, 2002)
  abstract   The mycoflora of roots of three species of oak (Quercus robur, Q. petraea, Q. rubra) from two localities near Moravské Budějovice (southwest Moravia, Czech Republic) with and without tracheomycotic symptoms was studied. Fifty-seven species of fungi were identified from the samples. The most frequently isolated were Fusarium solani, Penicillium gl and icola, P. glabrum, P. simplicissimum and Acremonium curvulum. In the roots of trees with tracheomycotic symptoms two species of ophiostomatoid fungi were recorded. Abiotic condiontions (insufieciency of precipitation and higher average temperature) are considered to be primary reasons of oak decline.
