684 SUMMARY OF CURRENT RESEARCHES RELATING TO 



but while some districts are well represented in that work, others, and 

 of these Emilia is one, have very poor records. The writer proposes in 

 this list to fill up the blanks left in the larger work. In general, he 

 has followed Jatta's system of classification, aud this first publication 

 includes £enera and species of Kamalinacere, Cladoniaceae, Sphaero- 

 phoraceae, and Parmeliaceae. 



A further instalment * contains species belonging to the genera 

 Umbilicaria, Gyi-ophora, and Endocarpon. The crustaceous lichens follow 

 in order, and those belonging to the Lecanoracei are included. 



Compounds from Lichens, f — W. Zopf describes the properties of 

 various acids and other chemical compounds ohtained from different 

 lichens. Some of the compounds are new to science. 



Kryptogamen-Flora.J — Andreas Allescher has issued another part 

 which continues the account of the Fungi imperfecti. He concludes 

 the genus Coryneum. Then follow the small genera Scolecosporium, 

 Aster osporium, Seiridium, and Seiridiella ; the two latter being very 

 closely allied. The two genera Monochsetea and Pestalozzia occupy the 

 remaining pages. The former genus has been hitherto regarded as a 

 sub-genus of Pestalozzia. Allescher raises it to generic rank, in order 

 to make the work of arrangement easier. The species are tabulated on 

 an alphabetical list of host plants — and the author found it simpler to 

 place all the forms of Monochsetea by themselves. The spores differ 

 from those of Pestalozzia in having only one appendage. 



Contributions to Fungus Floras. — N. Eanojevie § completes his 

 list of Servian fungi, 247 in all. There is one new species, Ascobohts 

 serbicus, included in this last contribution. 



P. Hennings j| describes the fungi collected by Puttemans and 

 A. Hammar at Sao Paulo during the years 1900 and 1901. They are 

 all microscopic and grow on leaves or branches of various plants. 

 Many new species are described, and three new genera, Puttemansia, 

 a member of the Pezizaceae with erumpent, globose and then cupulate, 

 hairy ascomata ; the spores fusiform — three-septate and yellowish — 

 hyaline, found on leaves of a member of Lauraceae. Pseudomelasmia 

 near to the genus Melasmia, one of the Leptostromataceae ; the conidia 

 are oblong, hyaline, and one-septate. Tetracrium, a Hyphomycete, bears 

 four radiate conidia at the tips of the conidiophores ; they are elongate- 

 fusiform, pluri-septate and colourless. 



Hennings % also publishes his Fungi Cosiaricenses I. received from 

 H. Pittier. There are a few Myxomycetes. There are no new genera. 

 Most of the species of fungi are microscopic ; many of them are new 

 to science. They have been collected at or near Costa Rica. 



Under mycological notes, A. Scherffel ** describes several new 

 Cbytridineae which he has found growing on green algae. They are
