THAXTER. — LABOULBENIACEiE. 473 



on one side and the neck-like base of the perithecium on the other. 

 Spores 95 X 5.5 /a. Perithecium 220-245 x 60-65 /x, its neck-like 

 base about 75 X 30 /x. Receptacle about 515 x 100 /x. Total length 

 to tip of perithecium 800-835 /x. 



On Galerita mexicana Chaud. Nicaragua. 



This species has been previously referred to by the writer as a 

 possible hybrid between L. mexicana and L. Galeritce. It seems on 

 more careful comparison, however, to be abundantly distinct from 

 either. The neck-like base of the perithecium appears to be formed 

 from the elongated basal wall cells of the perithecium which lie wholly 

 below the ascogenic cells. The eight types were found on the elytra 

 of their host in company with L. mexicana. 



Laboulbenia decipiens, nov. sp. 



Perithecium nearly opaque, not punctate, large, slightly and evenly 

 inflated, tapering rather abruptly to the nearly symmetrical apex ; the 

 basal wall cells forming a short stout clearly defined neck ; the septa 

 separating the upper wall-cells deeper blackish and spirally twisted. 

 Appendages arising as in L. Galeritce from a conical cellular base 

 consisting of one outer and two inner rows of superposed cells, each 

 of which bears a single simple straight septate branch, its lower seg- 

 ments slightly inflated, hardly exceeding the tip of the perithecium. 

 Antheridia blackish, with a very long curved neck, borne singly or 

 two together from the sub-basal cell of the inner series of superposed 

 cells. Receptacle as in L. Galeritce except that cell (3) extends 

 upwards nearly to the black insertion cell of the appendages, cells (4) 

 and (5) being wholly included by it. Color sub-hyaline with brownish 

 suffusions especially in the region of cells (4) and (5). Perithecium 

 175-278 X 55 jtt (smallest 130 X 37/*), its stalk-like base 40-55 x 30 /x. 

 Receptacle (larger) 300 x 75 /x. 



On Galerita cequinoctialis. Guatemala. 



This species is remarkable for its close resemblance to L. Galeritce. 

 It is at once distinguished by the position of cell (3), and by the pecu- 

 liar twist of its perithecial wall cells which are not punctate as in the 

 latter species. 



Laboulbenia Aspidogloss^, nov. sp. 



Perithecium black, almost opaque, rather narrow, the inner margin 

 curved abruptly outwards to the rather large apex, its lips very 

 oblique outwards. Appendages arising from two basal cells which
