328 SUMMARY OF CURRENT RESEARCHES RELATING TO 



reddening of the skin when taken along with alcohol. There was no 

 irritation, but the red coloration lasted several hours, and reappeared 

 at the next meal if wine were partaken. 



P. Dumee * has tested the toxicity of Entoloma Uvidiim. He ate a 

 portion of the pileus carefully prepared and cooked with butter for 

 twenty minutes. Somewhat severe effects resulted, repeated sickness, 

 wakefulness, etc., but the poison had no effect on the heart. 



Lepiota from the Nests of Termite Ants.f— M. Patouillard 

 describes a new fungus of this genus, L. Le Tesfui, from the Congo 

 region, which is very near to L. albuminosa Berk, and Br., an Eastern 

 species which occurs in a similar habitat. There are various differences 

 between the species, such as the presence or absence of a ring, a long 

 stalk, or one terminating in a root which may attain considerable 

 length ; they differ in the appearance of the pileus, dry and hairy in the 

 Congo plant, viscous in the plant from the East, and also in some other 

 particulars. A diagnosis of the new species is given. 



Clathrus cancellatus.| — J. Chiflflot reports the occurrence of this 

 very rare fungus at Saint-Genis-Laval (Rhone). Two groups of the 

 fungus were found in the soil ; from loose byphas there arose a thick 

 mycelial cord about 3 mm. in diameter, which branched and bore at the 

 tips of the branches one or two specimens of the fungus. The author 

 sees good reason for considering that insects aid in the distribution of 

 Clathrus^ as when the spores are mature a powerful odour is emitted by 

 the fungus which attracts the insects.

Anatomy of Agarics. § — A. Sarfcory draws attention to the increas- 

 ingly recognized importance of histological characters in Agarics, and 

 he gives details of a number of Tricholomas that he has examined. He 

 finds quite determinable differences in the form of the spores, the 

 radial section of the pileus, and in the surface of the pileus. Trickoloma 

 Georgii, T. nudum, T. chrysenteron and T. terrenm are the species dealt 

 with so far. 



New Parasitic Fungi. || — B. C.Tharp, plant pathologist in the Texas 

 Department of Agriculture, has collected and determined a large series 

 of microscopic pathogenic fungi, all of them found on living leaves of 

 various plants in his district. A very large percentage belongs to the 

 genus Gercospora. Other genera represented are Exosporium, Phyllostica, 

 Eamularia, Septoria, &c. Diagnoses are given and the host plant 

 indicated.
