Massee and Salmon . — Researches on 
paullo majoribus, nempe 5 /x diam., 4 /x e latere crassis; ascis 10 n 
diam. Hab. in fimo gallinaceo, Malacca (Scortechini)/ Prof. Sac- 
cardo has kindly sent us the type specimens of M. coprogenum and 
its var. malaccense, and we have identified them as being certainly 
Gymnoascus Reessii, Baran. In the example sent labelled ‘M. copro- 
genum , typicum/ the spores measure 3-4 x 2-2-5 /* ; the ultimate 
branches of the hyphae have exactly the form characteristic of 
G. Reessii (see Fig. 35). In the specimen sent labelled *f malaccense ’ 
the hyphae are similarly branched, but the spoyes are a little larger, 
though slightly variable in size. In front view they average 4 fx, and 
vary from 3*5-4-5 /x; seen from the side they measure 2-2-5 /* (not 
4 /x as stated by Saccardo). The habit in both specimens is that 
of G. Reessii ’ and the size of the spores also agrees with that found in 
this species.

Glomerulis gregariis, subrotundis, 90-120 /x diam., primo luteis 
deinde laete flavo-viridibus, hyphis dense intricatis irregulariter ramosis 
septatis 5-6 /x crassis ramulis apice bifurcato-uncinatis, appendicibus 
radiantibus teneris sparsis flexuosis ad apicem sensim attenuatis 
peripherice instructis; ascis subglobosis 8-9 ^ diam., octosporis, 
sporis hyalinis e fronte orbicularibus 3 -5-4 -5 diam., e latere ellipticis

Had. — In fimo murino, Aburi, Gold Coast, Africa (W. H. Johnston, 
1901). 
A very interesting species, occupying a somewhat intermediate 
position between the genera Gymnoascus and Myxotrichum , agreeing 
with the former in the dense protective network of hyphae being 
provided with numerous simple, or forked, uncinate free ends ; and 
with the latter genus in the habit of the nearly globose glomerules, 
and in the radiating appendages. These latter, however, are primitive 
in type, and scarcely differ from ordinary hyphae, being not yet 
differentiated into the rigid appendages — spine-like or with a curved 
or circinate apex — which are found in the typical species of 
Myxotrichum. 
The Fungus was sent in fine condition on Rats' dung from Aburi, 
Gold Coast, Africa, by Mr. W. H. Johnston, F.L.S. 
M. spinosum, sp. nov. (Figs. 63-66).
