About this book

Contains the following five articles:

Senn-Irlet, B.: The genus Crepidotus (Fr.) Stuade in Europe
The genus Crepidotus in Europe is considered. After an examination of 550 collections seventeen species and eight varieties are recognized. Two keys are supplied; all taxa accepted are typified.

Morphological, ecological and chorological characters are critically evaluated. Descriptive statistics are used for basidiospore size. An infrageneric classification is proposed based on phenetic relationships using different cluster methods. The new combinations C. calolepis var. squamulosus and C. cesatii var. subsphaerosporus are introduced. The spore ornamentation as seen in the scanning electron microscope provides the best character for species delimitation and classification.

Keizer, P.-J. & E. Arnolds: Taxonomical notes on macrifungi in roadside verges planted with trees in Drenthe (The Netherlands) - II
In the second part of this study special attention is paid to the genera Hebeloma, Psathyrella and Russula. Psathyrella rhombispora is described as a new species. Russula cicatricata Romagn., R. elaeodes (Bres.) Romagn. and R. purpurata Crawsh. are reduced to formae of R. graveolens Romell. in Britz.

Castro, M.L. & L. Freire: Gyroporus ammophilus, a new poisonous bolete from the Iberian Peninsula
Gyroporus ammophilus, a poisonous bolete occurring in Pinus woods on sandy soils along the western Atlantic coast of the Iberian Peninsula, originally published as a variety of G. castaneus, is formally raised to the rank of species. The distinguishing characters of Gyroporus ammophilus are given against G. castaneus (Bull.: Fr.) Quél. The new species causes severe gastroenteritis when consumed.

Noordeloos, M.E.: Notulae ad Floram agaricinam neerlandicam – XXIII. Psilocybe and Pholiota

Boerema, G.H., J, de Gruyter & M.E. Noordeloos: New names in Phoma
The names of two species of Phoma, discussed in our recent papers (de Gruyter & Noordeloos, 1992 and Noordeloos et al., 1993) appeared to be illegitimate as later homonyms (Art. 64). Therefore the following new names are proposed as avowed substitutes.
