with 49 species. In the latter genus Clayton Roberts Orton is named as collaborator for 

 all the species. The genus Klebahnia having 8 species is begun but only 6 of them are com- 

 pletely treated. Of new species and new combinations there are in this part 51 for Dicaeoma, 

 25 for Pucciniola, 10 for Allodus, and 5 for Klebahnia. The new combinations in Dicaeoma 

 represent transfers from Puccinia, Uredo, and Aecidium, those in Pucciniola transfers from 

 Aecidium, Uromyces and Puccinia, those in Allodus transfers from Puccinia and Aecidium, 

 and those in Klebahnia transfers from Uromyces. — The material here presented is the first 

 thorough taxonomic tvork on these groups in North America and it should be examined by 

 every student interested in the rusts. — E. B. Payson.

 Club 48: 31-42. 1921. — Puccinia pacifica BlasdaXe, P. irrequisita J a,ckson, Uromyces coordi- 

 natus, Ravenelia havanensis, and Lipospora tucsonensis are described as new species. Puccin- 

 ia additica Jackson & Holway nom. nov. for P. Coreopsidis Jackson & Holway, P. opposita 

 (Orton) comb, nov., P. Erigeniae (Orton) comb, nov., Polythelis suffusca (Holway) comb. 

 nov., and Gallowaya pinicola nom. nov. for G. Pini Arth. are given and the following new gen- 

 era are made: Lipospora and Teleutospora Arthur & Bisby, the latter being for 3 species of 

 Uromrjces {U. Rudbeckiae Orth. & Holw., U. Solidaginis Niessel, and U. bauhiniicola Arth.). 

 Micropuccinia Rostrup is discussed and to it are referred a number of species included by 

 Rostrup in 1902 as well as those short-cycle forms placed by him in Dasyspora. Ninety species 

 are here referred to Micropuccinia, and are to be credited to Arthur and Jackson. — P. A.

 indigens (Am.). [The thallus of the saxicolous fungi Phaeospora propria (Arn.) and Nectria 

 indigens (Am.).] Centralbl. Bakt. II Abt. 50: 45-54. Fig. 1-11. 1920.— By the term saxi- 

 colous fungi, the author designates fungi which grow and fruit on rock apparently free from 

 organic matter. The author has previously shown in the case of Pharcidium lichenum (Arn.) 

 and Didymolla Lettaniana Keiszl. that such fungi exist. The present investigations show 

 that Phaeospora propria (Arn.) is an endolithic lime fungus with a parasymbiotic mode of 

 life. It probably lives with vigorously developed and fruiting lichen beds as a parasymbiont. 

 Most significant, however, is the fact that the fungus has the power of penetrating deeply 

 into the lime not only by means of the lichen hyphae but also by means of true fungus hyphae. 

 If the dissolving of the lime is accomplished by means of COa produced in the respiration of 

 the fungus, it would appear that there are 2 types of saxicolous fungi, one with an accentuated 

 respiration (endolithic) and the other with normal respiration (exolithic). Nectria indigens 

 is an exolithic lime fungus which grows parasymbiotically with several lichen complexes but 

 in no way forms a truly combined lichen thallus. In its latest stages, however, the fungus 

 lives as a true parasite upon the engulfed lichen complex. The lichen seems to be the only 

 visible source of carbon for this saxicolous fungus. — Anthony Berg.

 Roy. Belgique CI. Sci. 1914: 280-285. 2 pi. 1914 [1919].— The author concerns himself here 

 with structures which from their shape and certain peculiarities he calls "glom^zules myc6- 

 liens." They occur in the cortex of the rhizomorphs. After describing their form and struc- 

 ture the author states that they do not constitute organs of propagation comparable to the 

 bulbils and tubercles of the phanerogams. — Henri Micheels.

 [Mycological notes. Series I. Ascomycetes. First part. On the occurrence of carotin crystals in 

 two new species of Peziza.] Hedwigia 59 307-312. PI. 2. 1918.— Two species of the Pezizales 

 are described as new, Humaria carota emd Ascophanus fimicola. Carotin in the form of prom- 

 inent crystals was found in the ends of the paraphyses and in the cells of the hypothecium.
