The Boletales is a morphologically diverse order of
Basidiomycetes that includes poroid, gilled, resupinate and
epigeous gasteroid fungi. The work presented here is
included in the Flora Micologica Iberica project. The main
purpose was to establish the relationships, based on
morphological, molecular and chemical data, between the
Boletales. Although, the main collections belong to the
Iberian Peninsula, material from all over the world were
included to compare with the Iberian ones. The
phylogenetic analyses, based on sequences of the ITS
regions including the 5.8S rDNA, allow to arise the
following conclusions: a) The boletoid, agaricoid, secotioid
and gasteroid basidiomes appear in different groups. The
genera with gills (Chroogomphus (Singer) O.K. Mill,
Gomphidius Fr., Hygrophoropsis (J. Schröt) Maire ex
Martin-Sanz, Neopaxillus Singer, Omphalotus Fayod, and
Paxillus F.) included in three families according to
Hawksworth et al. (Dictionary of the fungi, 1995) appear in
five clades. Only the family Gomphidiaceae is
monophyletic. b) The family Rhizopogonaceae is not
monophyletic. Alpova C.W.Dodge is not included between
the species of the genus Rhizopogon Fr. & Nordholm but
within the clade of the Boletus species. On the other hand,
Truncocolumella Zeller is closely related to Suillus species.
c) The family Suillaceae should include not only Suillus
and Gastrosuillus, but also Truncocolumella and
Rhizopogon.

Morels (Morchella spp.) are known to grow in a wide
range of habitats, in various places around the world,
usually for one extended wave of three weeks per season in
one site. However, in Northern Israel we have located
morel fruitbodies (M. conica), which appeared in several
waves from December until the end of April in one site.
The morels emerged on roadside, nearby various types of
trees. We have observed and recorded the changes in the
mushroom population size and the distribution of fruitbody
size, as well as changes in weather conditions. Over 150
initials, up to 1.5 cm long were counted in the beginning of
the first wave, but only less then half survived 2 days later,
some continue to develop up to 10 cm long. A correlation
was found between cold rainy days followed by warm dry
days and between fruitbody initiation and development.
These observations suggest that Morchella species are
adjusted to their geographical location, and can fruit for
several waves if weather conditions permit.

A survey was conducted to accumulate knowledge on the
biogeography of Leptographium and their association with
beetles in Japan. Seven species of Leptographium were
isolated from bark beetles infesting Japanese red pine in
Japan. They were L. pini-densiflorae, L. lundbergii, L.
serpens, L. wingfieldii, L. yunnanense, Leptographium sp.1
and Leptographium sp.2. Leptographium sp.1 was similar
to L. neomexicanum but different in the respect of having
more ellipsoidal conidia. Leptographium sp.2 resembled L.
procerum but was distinguishable with well-developed
base of stipe. These unidentified species are considered to
be undescribed. L. serpens and L. yunnanense are firstly
recorded in Japan. Others are already-known species in
Japan. Leptographium sp.1 was isolated from Hylastes
pulmbeus together with L. serpens. L. lundbergii and
Leptographium sp.2 was isolated from five beetle species,
Tomicus piniperda, T. minor, Hylurgops interstitialis,
Hylastes paralleus, and H. plumbeus. L. pini-densiflorae
was isolated from T. piniperda, T. minor, Cryphalus fulvus
and Orthotomicus angulatus. Leptographium wingfieldii
and L. yunnanense were isolated exclusively from T.
piniperda.
726 - The Genera Gymnopus and Rhodocollybia in the
southern oak forests of Costa Rica

Floristic and monographic studies in the genera Gymnopus
and Rhodocollybia in Europe and in northeastern United
States have been compiled recently (Halling, 1983;
Antonín & Noordeloos, 1997). Such studies have been
scarce, however, for these collybioid species collected in
tropical locations. Morphological studies on specimens
collected in the oak forests in the Talamanca Mountains of
southern Costa Rica have revealed eight species in
