XYLARIA HEMIGLOSSA, as illustrated from New Caledonia has same size 

 and shape as Xylaria reniformis, but small spores 5 x 7-8. 



XYLARIA FIBULA (Fig. 1089). We present 



a figure of a specimen at Kew, labeled Xylaria 

 fibula, by Massee, but not the plant published by 

 him under this name. The plant he so published he 

 labeled Phacostroma fibula, and in my opinion it is 

 not a Xylaria and should I publish it I would use 

 Massee's generic name, leaving the name Xylaria 

 fibula open for this plant. The genus Phacostroma 

 is a flat sessile, cushion shape plant, with soft, fibrillose, 

 carbonous tissue, quite different from the genus 

 Xylaria. I do not know why Massee, after so labeling 

 his specimens, should publish it under a different name. 



Xylaria fibula has a concave base, similar to Xylaria reniformis. It differs 

 in the smooth, even surface. I have no memorandum of the locality whence it 

 came, as when I photographed it I supposed (naturally) that it was the plant 

 he had so published. 



XYLARIA OBOVATA, FROM T. S. BRANDEGEE, MEXICO, 

 AND T. J. COLLINS, GUATEMALA (Fig. 1090). Plant dark 

 brown, obovate or globose, tapering into a 

 short, concolorous stipe. Surface even, glabrous, 

 nOt ru S u ' ose m drying. Stroma white or alu- 

 tuceous, soft, pithy, becoming hollow. Spores 

 6-8 x 28-32. In the West Indies we judge this 



is not rare. It is quite distinct from all related 



species by its soft stroma.

SYNONYMS. Xylaria tuberoides, discovered in Brazil by Rehm. Xylaria collabens as illus- 

 trated by Cooke, which, however, has no resemblance even remote to Montagne's illustration and 

 ran not possibly be his plant, although no one knows what it is. Penzigia obovata, as juggled by 

 SpegazZim. The plant is a true Xylaria, with no relation to Penzigia in the type idea. Xylaria Duchass- 

 aiingn, named by Rehm from Guadaloupe, is surely (and fortunately because of its barbarous name) 

 the same as Xylaria obovata. 



ALLEGED SYNONYMS. Xylaria dealbata from South America, not possible. Hypoxvlon 

 I or Xyllria^ea^bata ' "^ ^ M probable ' Penzi g ia actinomorpha from Brazil is for me a synonym 



XYLARIA RIDLEYI 

 Kew, from Singapore, 

 appears to me to be 

 same as Xylaria 

 obovata. The stroma 

 in the specimens 

 photographed a p - 

 pears to be curiously 

 two lobed, remind- 

 ing me of a coffee 

 berry. Of course if 

 this is a feature of 

 the plant it is not a 

 synonym of Xylaria 

 obovata. The spores 

 are given smaller 

 also, 4-5 x 18-20.

XYLARIA CAVERXOSA, FROM J. P. MOUSSET, 

 JAVA (Fig. 1092). Club globose, black, wrinkled. 

 Context white, hard, hollow. Stipe distinct, black,

smooth. Based on a single, immature specimen, we name 

 it simply to have a name for it in our museum. It was 

 referred for us to Xylaria obovata, but that is not possible.
