HYPOCRELLA AND ASCHERSONIA. 267 



Hypocrella obconica P. Honn., Fungi goyazenses, p. 10(3. 



This, in the type specimen in Herb. Berlin, is a discomycete. 

 It grew on decayed areas on the leaf, from a byssoid stroma. The 

 hypothecium is well developed, and forms an infundibuliforiu cup 

 filled with the obconic mass of asci. The spores appear to be 

 filiform. 



Hypocrella juruana P. Henn., Hedwigia, XLIV., p. 61. 



The type specimen in Herb. Berlin is XJle 2, 831, 2, 832. Hemiings 

 described it as subdiscoid, pulvinate, convex or flattened, horny 

 red-brown, 1-2 mm. diameter, granulato-ostjolate, pallid within ; 

 asci 150-200 x 4-5 \x ; sporidia 1 [j, diameter, as long as the ascus. 

 After the description he stated that the stromata were, in general, 

 quite immature, and only isolated sporif erous asci could be found. 

 In the type specimen in Herb. Berlin the stromata are circular, 

 flattened and lenticular, and as far as could be ascertained do 

 not contain any perithecia. Tliey are composed of thin-M'alled 

 hypha? and thus differ from Hypocrella in general, and they do not 

 exhibit the characteristic Hypocrella sear. They appear similar 

 to the barren stromata, common in the Eastern tropics, which 

 Berkeley named (in Herb.) Aschersonia zeylanica. I have 

 similar stromata frona Trinidad ex herb. Thaxter, 



Hypocrella Moelleriana P. Henn., Hechvigia (1897), p. 222. 

 Transferred to Ascopolyporus by Moller, Phycomyceten und 

 Ascomyceten, p. 1 80. 



Moelleriella nutans Rick, Ann. Myc, II., p. 105. 



This has already been referred to on p. 196. 



Hypocrella rubiginosa A. L. Smith, Jour. Linn. Soc, XXXV., 



p. 18. 



This was described as occurring on the stroma of a Hypoxylori' 

 The basal part, however, is not Hypoxylori, but Munkia. 



Other specinaens of Munkia examined by me exhibit, when dry, 

 an outer " rind," about 1 mm. thick, in which the " pycnidia" 

 are embedded, and this rind is continuous all over the stroma. 

 In tlie specimen which bears Hyjwcrclla ruhkjinosa, however 

 the outer rind is interrupted beneath the Hyimcrella stroma, as is 

 sliown in Miss A. L." Smith's illustration. The inner radially- 

 arranged hyphae grow through this gap and form the Hypocrella 

 stroma. It would appear that the tissues of tlie supposed two 

 fungi are continuous, and that the ascig erous portion is to be 

 regarded as the higher stage of the Munkia. The structure is 

 qviite different from what would be found in the case of a Hypo- 

 crella parasitic on a scale insect on another fungus. 



The ascigerous stroma differs from Hypocrella in the character 

 of its hyphse. Its spores are continuous and multiseptate, but it 

 is, of course,possible that they may ultimately fall into part-spores. 



Aschersonia mellea B. & Br., Jour. Linn. Soc, XIV., p. 89. 



Examination of the type specunen shows that this is a small 

 Crepidotus, pressed flat on the substratum : its spores measure 

 5-6 X 3-4 ;ji,.
