are branched and septate ; they vary much in thickness from 2-12 /x. 

 The conidiophores are erect, simple, rarely septate, and almost colour- 

 less ; the head varies from 12-19 /x in diameter, and their length from 

 280-300 fx. The conidia are round, smooth, and from 3-4*2 /x in 

 diameter: in colour they vary from grey, through green to brown. 



M. Bouchard * describes an affection of the hairs of the moustache 

 due to a form of Trichosporium which he found to be identical with the 

 jmrasite of chignons, Trichosporium Beigeli. The hairs are covered with 

 nodosities, and have a silvery look. The parasite was successfully culti- 

 vated on carrots, and produced in two days white, somewhat inclining to 

 yellowish, growths of the fungus. 



Mycology in France. - ]" — A lengthy account is given of the excursion 

 of the members of the Societe Mycologique to the Jura. M. Poirault 

 describes a new member of the Chytridiacese, Woroninopsis radicicola, 

 which grows on the roots of Azolla filiculoides ; also a new species 

 of Endophyllum, parasitic on Centranthus ruber, which he named E. Cen- 

 tranthi rubri. M. Patouillard exhibited Microstroma album on oak leaves. 

 He finds that instead of a monosporous conidiophore, there was developed 

 at the tips a swelling bearing six conidia. He therefore creates a new 

 genus for the parasite which is henceforth to be known as Hetero- 

 stroma album Pat. P. Dumee and E. Maire present a note on Zaghouania 

 Phyllyreee, a genus of Uredineae found in Corsica on the leaves of 

 Phyllyrea, which Patouillard had placed in the family Coleosporiacere. 

 The authors conclude that the genus ought to form a distinct family, 

 which they name Zaghouaniacese. The teleutospore germinates in situ 

 as does that of Coleosporium ; but there is a probasidium in Zaghouania 

 though only partly encysted, and on germination the protobasidium does 

 not entirely leave the teleutospore. M. L. Holland laid before the 

 Society a new hymenomycete, Tricholoma bisontinum Roll., gathered in 

 the neighbourhood of Besancon. M. Holland also described to the Society 

 his methods of photographing fungi. Doctors Victor and Xavier Gillot 

 publish an account of cases of poisoning by species of Amanita and 

 Bussula. M. Patouillard describes some new or little known fungi 

 from Algeria and Tunis. The new species are Gymnosporangium 

 gracile on Juniperus Oxycedrus, Cintractia algeriensis, which destroys the 

 flowers of Danthonia Forskalii, Cortinarius Aurasiacus, Coprinus dr>jophilus y 

 Melanopus tunetanus, Mydnum chlorascens, a var. lachmopoda of Helvella 

 sulcata, Phragmonsevia Lauri parasitic on the leaves of Laurus nobilis, 

 Sphserella Hertise, and a new genus Helostroma in which the author has 

 placed Fusisporium album of Desmazieres. It is a parasite on oak leaves. 

 Prof. Van Bambeke contributes an account of a monstrous form of Poly- 

 porus sulphureus which grew in the gallery of a mine. 



L. Matruchot and C. Dassonville describe a new pathological fungus 

 Trichophyton caninum which causes a scurf on the skin of dogs. Iu 

 cultures the fungus produced tufts of mycelium with intercalary chlamv- 

 dospores and lateral spores on short stalks. 



M. Barbier contributed a list of Hymenomycetes from the neighbour- 

 hood of Dijon. It is a continuation of the list published in the Bulletin 



* Comptes Reudus, exxxiv. (1902) pp. 316-8.
