Differs mainly from the typical form in the reduced length of the 
spines, and in the somewhat shorter spores with fewer septa, 7-9 
being the most frequent numbers, although it is not unusual to find 
odd spores with a greater number of septa ; I have seen a spore with 
15 septa in the same ascus with seven others having 9 septa each, in 
Cooke's type of var. americanum. 
Form Walteri. (PI. XIII, Figs. 78-80.) 
Spores 60-75 x 5~6 pale brown, most frequently 3-5-septate, but 
occasionally 7-9-septate ; spines scanty, not at all, or only very little, 
longer than the asci. 
Syn. — Geoglossum Walteri , Berk., in Cooke, Mycogr. 4, fig. 4 (which 
is altogether inaccurate); Sacc., Syll. viii, n. 149, 1889. 
Geoglossum Farlowi, Cooke , Grev. xi, 107, 1883; Sacc., Syll. 
viii, n. 148, 1889. 
Hab. — Among grass and on trunks of tree-ferns. 
Distr. — Britain (Twycross, Bloxam ), United States (Newton, Mass., 
Farlow ), Australia (Wild Dog Creek, Apollo Bay). 
This condition maybe considered as a continuation of the reduction 
in length of spines, and size and number of septa of the spores, com- 
menced in form americanum. In the present form the spores are 
most frequently 3-septate. 
Cooke first suggested G. Walteri as a species to Berkeley, the latter 
having considered it as G. hirsutum , whereupon Berkeley gave the 
specific name of Walteri , leaving Cooke to draw up a diagnosis of 
the species. Judging alone from the figure and description given in 
Mycographia (4, f. 4), the form appears to have no close affinity with 
G. Farlowi , Cke., but I have carefully examined the type, and find 
that Cooke has drawn the spines too long — they are in reality not 
much longer than the asci ; the spores are also too long, and the 
3-septate form is most usual. 
Following the diagnosis of G. Farlowi (Grey, xi, 107), Cooke says, 
* It is very much a matter of opinion whether this ( G . Farlowi ) and 
G. Walteri , C., and G. velutipes , Pk., should be regarded as varieties 
of G. hirsutum , or as distinct species.' 
Form velutipes. 
Subcaespitose, black ; club [ = ascigerous portion] short, compressed; 
stem densely clothed with a very black, velvety pubescence. Asci
