Between 2002 and 2012 regular visits to the Carpathians were made and a number of Hebeloma spp. were collected from the alpine area. In total 44 collections were made that represent 11 species, two of which, Hebeloma grandisporum and H. oreophilum, are described here as new. Of the 11 species, four (H. alpinum, H. marginatulum and the two species described as new) are known only from alpine or Arctic habitats. Hebeloma dunense and H. mesophaeum are commonly found in, but not restricted to, alpine habitats. The other five species (H. aanenii, H. laterinum, H. naviculosporum, H. vaccinum, H. velutipes) are usually found in lowland or boreal habitats. Hebeloma naviculosporum is reported for the first time from the alpine zone and H. alpinum for the first time as growing with Helianthemum. All but two species (H. alpinum, H. marginatulum) are reported for the first time from the Carpathian alpine zone. In this paper we discuss the habitat, the 11 recorded species and give detailed descriptions of the two new species, both morphologically and molecularly. A key for Hebeloma species from sect. Hebeloma occurring in Arctic-alpine habitats is provided.

“…The genus Polxllus seems to share an intermediate position between two groups of angiosperln genera. One including genera such as Snli,~, Querc.us, and EucnIyptus forms exclusively epidermal Hartig nets (Godbout and Fortin 1983); the other, such as Cistus and Dryns, forms full cortical Hartig nets (Debaud et a]. 1981;Giovannetti and Fontana 1982).…”

“…The studies mentioned above have in common the use of 10 to 30% H2O2 for 10 to 30 minutes to surface-sterilize the seeds. Other studies have, instead of H2O2, used sterile distilled water and silica sand (GODBOUT and FoRTiN 1983;MASSICOTTE et al 1989), commercial bleach solution (LALONDE 1979), or mercuric chloride (DEBAUD et al 1981) to sterilize the seeds, but these studies did not screen for contaminants.…”

A new method to produce numerous uncontaminated alder seedlings

Seeds of four species oi Alnus were surface sterilized and placed on plates containing water agar. After seedlings had been produced, they were, without the seed coats attached, transferred onto malt agar plates. On such media, possible contaminants grew quickly and contaminated seedk ings couM be detected and discarded. With this method, numerous uncontaminated seedlings can be produced and used for synthesis experiments.
