2. Midotia nicaraguensis (Durand) Seaver, comb. nov. 



lonomidotis nicaraguensis Durand, Proc. Am. Acad. Sci. 59: 11. 1923. 

 Ciboria caespitosa Seaver, Mycologia 17: 48. 1925. 

 ?Ionomidotis portoricensis Seaver, Mycologia 17: 50. 1925. 



Apothecia closely clustered, or coalesced at the base, at first 

 closed, then opening and expanding so as to become applanate 

 (when dry), sessile, attached at one side of the base, reaching a 

 diameter of 1-2 cm., externally dark ferruginous-brown, verru- 

 cose; hymenium blackish-brown, becoming dark reddish-purple 

 when wet; asci cylindric-clavate, the apex rounded, reaching a 

 length of 135-150 and a diameter of 8 ;u, 8-spored; spores 1- 

 seriate, hyaline, smooth, 5-7 X 15-18 y,; paraphyses slender, 

 hyaline, below, slightly thickened and brownish at their apices. 



On rotten logs. 



Type locality: Nicaragua. 



Distribution: Nicaragua and Porto Rico. 



Illustrations: Proc. Am. Acad. Sci. 59: pi. 1. 



Our species from Porto Rico agrees so closely with Durand 's 

 description that we feel safe in combining them. lonomidotis 

 portoricensis is close to Ciboria caespitosa and may be identical. 

 The material is scant.

lonomidotis plicata Durand, Proc. Am. Acad. Sci. 59: 12. 1923. 



Apothecia small, clustered, or several arising from a common 

 base, at first closed, then opening by a pore, becoming unsym- 

 metrically goblet-shaped, resembling a minute Urnula Craterium, 

 reaching a height and width of 1-2 mm., externally black when 

 moist, brownish-black when dry, externally granular-furfura- 

 ceous, the substance thin, dark violet-brown and opaque under 

 the microscope; asci cylindric-clavate, the apex rounded, reach- 

 ing a length of 65-70 n, 8-spored ; spores irregularly 2-seriate, 

 smooth, hyaline, narrowly ellipsoid, straight or strongly curved, 

 2-3 X 5-8 n; paraphyses abundant and often forked, the con- 

 tents pale violet-brown, the tips slightly swollen and darker.
