Mucronoporus isidioides, (Berk.). The specimens of this species 
in de Thlimen’s Mycotheca 1105, from South Africa, as well as those from 
Ohio (ex herb. Berk.), have spines of the same appearance as in the 
specimens of P. gilvus , and this is another indication that this so-called 
species is only a form of P. gilvus. 
Mucronoporus setiporus, (Berk.). (Specimens from Ceylon, com. 
Cooke.) 
Spines 25-30 by 4//. 
Mucronoporus licnoides, (Mont.). (Specimens from Brazil, com. 
Cooke.) 
Spines abundant, rather short, 15-20//. 
Mucronoporus cichoriaceus, (Berk.). (Fro?n Australia, com. 
Cooke.) 
Spines quite abundant, projecting 25-35/* long, and about 5/* thick at 
the base. 
Mucronoporus tabacinus, (Mont.). (From New Zealand, com. 
Cooke.) 
Spines more abundant than in the specimens collected by Dr. Martin 
in Florida and distributed in N. A. F. 1705. 
Mucronoporus spongia, (Fr.). (Specimen from Cooke.) 
Spines 20-25 by 0-8//, curved like the spines on a rose bush. 
Mucronoporus crocatus, (Fr.). (Specimens in Rav. F. Am. 707 
and 708.) 
Spines 25-30 by 4-5//. 
Mucronoporus balans^e, (Speg.). 
Fungi Guaranitici Pugill. 1. No. 42. Spines 20-25 by 5-0//. 
In the measurement of the spines we have given the length of the 
projecting part. The base of the spines penetrates more or less deeply 
into the hymenial layer of the pores, and if this is included the length 
will be somewhat greater. 
TRIBLIDIUM RUFULUM (SPRENZEL). 
By J. B. Ellis. 
This appears to be a variable species. The specimens in Rav. Fungi 
Car. Exsicc. II, No. 47, have the sporidia oblong, slightly curved, 
nearly opaque, 3-septate, 24-30 by 10-12//, very slightly or not at all 
constricted at the septa. Specimens found by Mr. Langlois (No. 130) 
on dead tig tree in Plaquemines Parish, La., agree with Haveners Car- 
, olina specimens, unless in having the sporidia a little more constricted. 
In the specimens from both these localities the hymenium is of a deep 
brick-red color and the lips are slightly transversely striate. Specimens 
. collected at Ocean Springs, Miss., in February, 1887, by Mr. F. S. Earle 
(No. 202), agree with the Carolina and Louisiana specimens in all re¬ 
spects except in having the sporidia only 1-septate and a little smaller
