10 Eumycetes. 



The author classifies Tuber interniediuni Buch, and T. siiecicum 

 Wittrock as belonging to T. maculatum Vitt. The genuine T. rapaeo- 

 doriini Tul, has not yet been found in Scandinavia, the plants 

 classified under this species belong to Tiiher maculatum. Chaeroniy- 

 ces venosus (Fr.) Th. Fr. was hitherto generally called Ch. meaiidri- 

 formis V^itt. or Ch. gibbosus (Dicks.) Schroet, the author rejects, 

 however, Dicksons description as too brief and unreliable, raain- 

 taining that the name, given by Fries, Mylitta venosa was published 

 in Vet. Akad. Handl. 1830 p. 248, the year preceeding the publica- 

 tion of Vittadini's Monographia Tuberacearum. The description of 

 Militta venosa, found in Sacc. Syll. VIII p. 908 is not in conformity 

 with that of Fries. The name ElapJiomyces niuricatus Fries Syst. 

 myc. III 1829 is to be preferred to E. variegatus Vitt. 1831 as also to 

 the doubtful name E. scabev (Willd. 1787) Schroet. As to ElapJiomy- 

 ces granulatus (A. & S.) Fr. the author states it to be the favorite 

 food of various animals (Cervus, Sus, Sciurus, Canis vulpes, Lepus, 

 Mustela, Erinaceus and Nucifraga). The fungus found by Linne 

 during his Lappland tour and mentioned by him in his „Florula 

 Lapponica" as genuine trufifles must no doubt be classified under 

 this genus; and likewise the fungus found in the Island Mors about 

 1790 by dean Schade, which was described by Fries as a particular 

 species: E. rugosus. 



The author ist most inclined to consider Cenococcum geophüum 

 (Fries) as dead and subfossile. Hymenogaster griseus Karst, is classi- 

 fied under H. vulgaris Tul. and both Rhisopogon virens Karst, and 

 Rh. virescens Sacc. are classified under Hysteranghnn clathroides 

 Vitt. The name of Rhisopogon roseolus (Cda) Th. Fries, Syn: Splan- 

 chnomyces roseolus (Cda) apud Sturm 1837 is to be preferred to that 

 of Hysterangium rubescens Tul. 1843 and Rhisopogon rubescens Tul. 

 1844. According to the Information in band Sclerodenna vulgare 

 must be considered an innocuous and eatable fungus. 



A new species Gautieria retirugosa and a new variety, Rhiso- 

 pogon roseolus (Cda) Th. Fries form, aberrans are described in 

 Latin, A list of one hundred books gives evidence of the profound- 

 ness with which the autor has treated the said subject.

Magnus, P., Ein kleiner Beitrag zur Kenntniss parasitischer 

 Pilze Liguriens. (Mitt. thüringischen bot. Vereins. XXVII. p. 

 13—17. 1910.) 



Verf. hat die von J. Bornmüller im Frühjahr 1909 an den 

 Küsten des östlichen Liguriens gesammelten parasitischen Pilze 

 bearbeitet. 



Unter diesen ist bemerkenswert Ustilago Vaillantii Tul., der 

 sehr häufig auf Muscari comosum Mill auftrat. Er deformiert die Peri- 

 gone der befallenen Blüten und bildet so nach der Mitteilung von 

 Herrn Bornmüller die var. Calandrinianum (Pari.) Asch, et Graebn. 

 Entyloma Helosciadii P. Magn. trat in seiner Conidienform [Cylin- 

 drosporiutn Helosciadii repentis P. Magn.) auf Helosciadium nodißoruni 

 Koch (? oder Betida angustifolia) auf. Da sie R. Maire jüngst bei 

 Saida und auf Corsica nachgewiesen hat, möchte diese Art in den 

 Mittelmeerländern recht verbreitet sein. Auf Lotus ornithopodioides 

 wurde ein zu der Verwandtschaft von Urom. Medicaginis falcatae 

 (DC.) Wint. gehöriger Uromyces an demselben Standorte mit dem 

 Aecidium Euphorbia nicacensis All. gefunden, die daher vielleicht
