594 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Kad. Lloyd has found in the States and in Samoa tbo plant that was 

 figured and described by W. G. Smith under G. slriatus D.C. After 

 examining and comparing the different specimens, he concludes that it 

 is altogether different from the typical G. striatus, and he has re-named 

 it G. Smithii. The species arc all illustrated by photographs. 



European Agarics.*— G. Massee has just published a classified list 

 of these fungi, with a short description of each species. It is a handy 

 compilation, and is intended to widen the outlook of home systematists, 

 and give them a better grasp of species as a whole. The work includes 

 descriptions of 2750 species, of which 1553 are British. The species 

 not yet recorded for Britain are indicated by brackets. A scanty biblio- 

 graphy is given at the end of the book. 



Rhizomorpha. f — Jules Goffart has studied the form and development 

 of the rhizomorpha of Armillaria mellea. It grows usually in long 

 strands under the bark of dying trees, and passes out into the soil to a 

 considerable distance. A strand that had grown into a stream was also 

 examined and compared with those that grow in the ground. He finds 

 in the rhizomorpha a medulla of primary hypbaa, along with secondary 

 hyphae. This central portion increases in diameter, and the hyphaa grow 

 outwards and form the cortex, which is thus continually renewed from 

 the interior. The author finds in the structure reserve hyphae and vas- 

 cular hyphae. These latter were fewer in number in the aquatic 

 specimen. 



American Mycology. — After an interval of several years, the 

 Journal of Mycology \ is now being reissued under the editorship of 

 W. A. Kellerman, of the Ohio State University. The contents of the 

 June number include a paper on the Morchellae, by A. P. Morgan. He 

 groups all the specimens he has found under two species, Morchella 

 esculenia and M. patula. The editor publishes a new species, ffltytisma 

 concavum, found growing on leaves of Ilex verticillata, and characterised 

 by the concavity of the stroma on the under side of the leaf. J. C. 

 Arthur gives a further instalment of his work on the cultures of 

 Uredineae. He has been dealing with Carex rusts, and for three of them 

 he proposes new names. The aecidia grow on various Dicotyledons. 

 Kellerman gives a list of the plants included in Fascicle IV. of his 

 Ohio Fungi, with a descriptive note appended to each species. J. B. Ellis 

 and B. M. Everhart publish a long list of new Alabama fungi, col- 

 lected by George W. Carver. They are all small fungi, and belong to 

 the Sphaeropsideae, the Pyrenomycetes, Hysteriaceae, Discomyces, and 

 Hyphomycetes. A considerable part of the number is occupied by an 

 alphabetical list of articles, authors, subjects, new species, and hosts, all 

 pertaining to the subject of Mycology. The frontispiece to the number 

 is a portrait of J. B. Ellis.
