Abstract A description is provided for Tapesia evilescens, a saprobe on dead stems of grasses, particularly the common reed (Phragmites australis). Some information on its substrata, habitat, dispersal and transmission and conservation status is given, along with details of its geographical distribution (Europe (Finland, Netherlands, Ukraine, UK)).

Reed Bed

In this study an attempt has been made to estimate the vitality of the common reed (Phragmites australis) grown in the constructed wetland. The efficiency of solar radiation uptake of leaves was measured and terminal electron transport system (ETS) activity of roots was determined in specimens from different locations on the reed bed. The results showed that photochemical efficiency of PS II, expressed as FvFm ratio, was higher in plants growing in the middle of the well established stand, but it was lower in plants growing in the area permanently flooded with leachate, where plants were significantly lower. Potential respiration of roots on the vertical rhizome decreases with depth, while it showed slight variations when determined at the same depth, but in plants from different locations within three beds of RBTS.

Lipara lucens Meigen (Diptera, Chloropidae) is a monophagous herbivore of the common reed, Phragmites australis Cav. (Trin.) ex Steud. (Poaceae), on which it induces typical cigar-shaped galls. In this paper, the anatomy and histochemistry of galls, cultivated in a greenhouse and collected in the field, were examined. Gall growth takes place while the larva feeds outside the actual developing gall. During gall growth, internode elongation is reduced. Internally, the pith parenchyma, destined to become the nutritive tissue, proliferates instead of degenerating as is seen in uninfested stems. The tissue cylinder around the gall chamber widens up to three times its normal size, while the pith parenchyma doubles its width. The central pith of nutritive cells becomes surrounded by an inner layer of longitudinal and an outer layer of radial parenchymatous cells. Vascular strands, likely connected to the vascular tissue of the host plant, run through this special band of parenchyma cells. The bundles are oriented perpendicular to the stem axis, surrounding the larval chamber. When the gall is completed, the larva gnaws through the growing point and enters the gall chamber, where it consumes the nutritive tissue. A sclerenchymatization process starts now resulting in an extremely hardened gall. Histochemical staining reveals the presence of proteins, DNA, RNA, and a gradient of lipid globules in the nutritive tissue. No starch was detected.Key words: plant-insect interactions, Lipara lucens, Phragmites australis, gall structure.
