Hypogeous Fungus

Eighteen Pisolithus basidiomes were collected from Eucalyptus plantations in the state of Minas Gerais, Brazil. These basidiomes were characterized morphologically and molecularly. The basidiomes varied in shape, color and size. One of them was found underground, indicating a hypogeous fungus. The main morphological distinctive characteristic was spore ornamentation, which distinguished two groups. One group with short and erect spines was identified as Pisolithus microcarpus, and the other with long and curved spines as Pisolithus marmoratus, after analyzing the cladogram obtained by phylogenetic relationship based on internal transcribed spacer (ITS) regions of the nuclear ribosomal DNA of these isolates.

Rhodiola Integrifolia

We investigated the relationship among North American Rhodiola integrifolia Raf., Rhodiola rosea L., and Rhodiola rhodantha (A. Gray) H. Jacobsen by sequencing a fragment of the nuclear-encoded chloroplast-expressed glutamine synthetase (ncpGS) gene from these three species and from selected Asian representatives of the genus. We found that R. integrifolia is a hybrid descendant of R. rosea and R. rhodantha lineages. We also found that the ncpGS gene and the internal transcribed spacer regions of the nuclear ribosomal DNA of Asian Rhodiola algida Fisch. & Mey. are very similar to those of R. rhodantha. In accordance with known chromosome numbers and species morphology, we therefore propose to move R. algida into the subgenus Clementsia of the genus Rhodiola, which so far contains only two species, R. rhodantha and Asian Rhodiola semenovii (Regel & Herder) Boriss.
