SUMMARY OF CURRENT RESEARCHES RELATING TO 
Homothallism and the Production of Fruit-bodies by Mono- 
sporus Mycelia in the Genus Coprinus. — Irene Mounce ( Trans . 
Brit. Mycol. Soc., 1921, 7, 198-217, 2 pis.). The author has followed 
on the lines of investigation of Bensaude and Knief. Bensaude dis- 
covered that in certain species mycelium produced from one spore 
would not develop fruit-bodies ; whereas the mycelia from two or more 
spores fused and formed clamp connexions and conjugate nuclei. 
Mounce has found in the genus Coprinus that in some species there is 
development, of fruit-bodies from one spore, while in others a mixture 
of mycelia is necessary — i.e. some are homothallic, others heterothallic. 
A list of the fungi experimented with is given, the methods are de- 
scribed, and the results set out in detail. A. L. S. 
Mycological Contributions. I. — F. Petrak ( Hedwigia , 1921, 62, 
282-319). Petrak publishes a critical survey of a large number of 
herbarium microfungi. He finds reason to establish new genera for a 
series of these fungi : Khekia based on Calospora ambigua ; Allanto- 
porlhe on Diaporthe tessella Rehm ; Disco diaporthe on species of 
Diaporthe ; Botryosphseo stroma on Fusicoccvm Ellisii ; Diploplacosphseria , 
a new discovery, a stage form of some Dothideaceee ; and Gloeosporidiella 
on Glceosporium ribis. A. L. S. 
Imperial Bureau of Mycology. — E. J. Butler (Trans. Brit. Mycol. 
Soc., 1921, 7, 168-72). The paper sets forth the reasons why a bureau 
was es'ablished at Kew — its aims and achievements. Its chief func- 
tions are : the accumulation and distribution of information ; publica- 
tion of abstracts ; formation of a library ; identification of fungi : 
study of parasitic fungi ; formation of a herbarium of parasitic fungi ; 
provision of laboratory facilities ; control agency on matters suitable for 
legislation ; and, finally, the stimulation of other branches of mycology 
as opportunity arises. A. L. S. 
New Fungi. XVI. — H. and P. Sydow (Ann. Mycol., 1920, 18, 
154-60, 1 fig-)- A descriptive list of microfungi from many localities 
in Europe and beyond. All of them are new to science. A. L. S. 
Notes on Some Interesting or Little-known Fungi. — H. and 
P. Sydow (Ann. Mycol., 1920, 18, 178-87). The authors are dealing 
with fungi already published. For JEcidium echinaceum Berk., from 
Ceylon, they propose a new genus Xenostele. They criticize Lloyd’s 
notes on Paulia resinacea , and point out that the name Paulia already 
exists as a genus of Pyrenopsidacese. They propose Xenostoma to 
replace Paulia, and a new genus of Hypocreacese, Apiocrea , distinguished 
by the form of the spores. A. L. S. 
Fungi Sinenses Aliquot a Cl. Prof. Otto Reinking coilecti et 
communicati. — P. A. Saccardo (Philippine Journ. Sci ., 1921, 18, 
595-605). A list of microfungi from various districts in China. 
Habitat and localities are given, and descriptions in the case of new 
species, of which there are a fair number. A. L. S.
