SYNONYMS (AND ALLEGED). Theissen gives the following synonyms: Xylaria tigrina, 

 as distributed by Rick is this species whatever it may be in original sense. Also Xylaria barbata as 

 illustrated by Starback. Xylaria ramuligera is a conidial state apparently. Xylaria collabens, we 

 know only from Montagne's account and figure. We found no type at Paris. But from the figure 

 it can not possibly be this plant. Xylaria eucephala is also known only from the figure from Malay, 

 which has no resemblance to Xylaria comosa. I think comosa is confined to the American tropics. 



XYLARIA FURCELLATA. We present a photograph (Fig. 1087) of this 

 "species," all that is known, which was "described" from India thirty years ago, 

 and to this day is only known from the "type locality." Berkeley got it years 

 before, but it was so poor he would not publish it, but Cooke dug it out and gave 

 it to "science." He also improved on nature by making a drawing of it that in 

 no way resembles the plant. Needless to say, nothing is known about Xylaria 

 furcellata except that it appears to have its conidial spores borne above. Myco- 

 logical literature would be better off if it were not encumbered with it. 



THE GLOBOSE XYLARIAS 



There is a small section of Xylaria, characterized by globose 

 or subglobose form. Most Xylarias are club shaped. It is probable 

 that some of these globose Xylarias have in old times been classed as 

 Hypoxylons, but as we have never worked over this genus we do not 

 know. This introduces the question of what is the distinction between 

 globose Xylaria and Hypoxylon. The only difference we are able 

 to point out is that Xylaria is stipitate and Hypoxylon sessile and 

 usually broadly attached. Most Hypoxylons that we know have 

 carbonous stroma, and Xylarias white stroma, but I do not know 

 that that applies to all Hypoxylons. We have specimens of three 

 subglobose Xylarias as follows: 



XYLARIA RENIFORMIS, FROM M. R. ESPINOSA, CHILE 



(Fig. 1088). Plant black, with 

 a short, smooth, glabrous stipe. 

 Club depressed, globose with 

 concave base, rugulose in dry- 

 ing. Stroma hard, white, be- 

 coming hollow. Spores 6-8 

 x 28-30. This, known only 

 from South America, was named 

 by Starback. Theissen refers it 

 in error to Xylaria obovata.
