Deyeuxia nyingchiensis is here recombined as Calamagrostis nyingchiensis comb. nov. as a result of recent studies of worldwide Agrostidinae. A new record of C. nyingchiensis is reported from Shangri-la (Zhongdian) County in Yunnan Province, SW China. Previously, C. nyingchiensis was noted from eastern Xizang and southern Sichuan, SW China. It is compared with the morphologically similar species C. scabrescens. A map with all known geographic records of C. nyingchiensis is presented.

Four keratinophilic fungi isolated from deer horn collected in Gorce National Park (Poland) are reported: Amauroascus kuehnii Arx with its malbranchea-like anamorph, Isaria fumosorosea Wize, Mortierella elongata Linnem., and Penicillium spinulosum Thom s.l. The record of Amauroascus kuehnii is its second locality in Europe, and keratin deer horn is a new substrate for this fungus.

This paper reports the first sites of Meottomyces dissimulans (Berk. & Broome) Vizzini in Poland. About a dozen basidiomata in all stages of development were observed in poplar and alder-willow thickets. The macroand micromorphological characters of the Polish specimens are described and illustrated, and the distribution of the species in Poland is given.

. This study examined the formation of successive rings of cambia in Rivea hypocriteriformis Choisy (Convolvulaceae). The mature stem is composed of four to five rings of xylem alternating with phloem. Successive cambia originate as smaller and larger segments; union and anastomosing of small cambial segments often leads to the formation of discontinuous rings. In the initial stage of growth, several vascular bundles interconnect to form the first ring of vascular cambium. The cambium remains functional for one complete season and becomes dormant during summer; a new ring of cambium is completed prior to the subsequent monsoon season and sprouting of new leaves. Successive cambia are initiated from the pericyclic parenchyma situated three to four cell layers outside of the protophloem. Functionally, all the successive cambia are bidirectional and produce secondary xylem centripetally and phloem centrifugally. The secondary xylem is diffuse-porous, with indistinct growth rings and consisting of wide fibriform vessels, fibre tracheids, and axial and ray parenchyma cells. The xylem rays are uni- to multiseriate and heterocellular. The multiseriate rays contain lignified marginal ray cells and thin-walled, unlignified central cells. The central ray cells also show accumulations of starch and druses. Discrete strands of intraxylary phloem occur at the periphery of the pith, and additional intraxylary phloem develops from adjacent cells as secondary growth progresses. Earlier-formed phloem shows heavy accumulation of callose, followed by its compaction. The development of successive cambia is correlated with extension growth and with the phenology of the plant. elements, fibriform vessel elements and xylem fibres, small pieces of xylem adjacent to the outermost cambial ring were macerated with Jeffrey’s fluid (Berlyn & Mik sche 1976) at 55–60 ° C for 24 to 36 h. Macerated pieces were stained with 1% aqueous solution of safranin, and temporary slides were mounted in glycerine. The length of fusiform cambial cells and sieve tube elements was measured directly from tangential longitudinal sections. Thirty random measurements were used to calculate means and standard deviations. Wood descriptions follow Wheeler et al. (1989) and Carlquist (2001).

This study examined wall ultrastructure variability in the microscopic green alga Pediastrum s.l. Its value as a diagnostic character is discussed. Field and cultured material of 21 taxa were compared using light and scanning electron microscopy. Nine ultrastructural elements occurring on the surface of Pediastrum are documented with LM and SEM micrographs. The highest number of taxa showed reticulate ornamentation composed of a trigonal mesh and granules situated on its corners. The paper considers the use of wall ultrastructure to reconcile traditional and modern taxonomical systems with regard to Pediastrum varieties, and addresses the phylogenetic relationships between strains representing different varieties.

This epiphytic moss was found at four localities in the Pojezierze Lubuskie lakeland in the western part of the country. Its diagnostic features are briefly presented, its habitat requirements are considered, the historical and recent findings of the species in Poland are dis - cussed, and its distribution is mapped.
