JiARLAEA. 399 



Type specimen examined, also specimen in Rehm's Ascom., 

 n. 451 (called Plicaria tracheia). 



Distinguished by the dark brown colour of the ascophore 

 and the large, areolate spores. 



The present species is the type of the genus Boudiera, 

 founded by Cooke — Grev., vol. vi. p. 76 — and which he 

 considered as belonging to the Ascoboleae and allied to 

 Ascobolus, differing in the globose spores. In the description 

 of Boudiera, Cooke saj's the hymenium is papillate and the 

 asci exserted ; this point I have not been able to corroborate, 

 but I find the paraphyses constantly longer than the spores. 

 The structure of the excipulum differs from that of the 

 Ascoboleae, and would be unique in that group, whereas it 

 agrees well with Barlaea and Humana. Phillips says the 

 spores are " deeply areolate, hyaline, brownish ; " I have not 

 seen the brown colour in the specimens examined. 



Barlaea schizospora. Sacc, Syll., iv. n. 442. 



Ascophore sessile, 4-7 mm. across, urceolate then plane, 

 brown with a tinge of red, then brown, disc sometimes paler, 

 margin entire ; externally minutely granular or pruinose ; 

 cells of excipulum polygonal, thin walled, very large, 30-50 

 /x diameter ; attached to the matrix by hyaline septate 

 hyphae originating from the basal cells of the excipulum ; 

 asci cylindrical, tapering at the base to form a pedicel; 

 spores 8, uniseriate, hyaline, permanently smooth, 1-guttu- 

 late, 12-16 /jl diameter ; paraphyses stout, septate, expanding 

 into a clavate or pyriform apex 4 fx thick, and containing 

 brownish granules when fresh.

On burnt sandy soil, charcoal, &c. 



On examining a portion of the type specimen, sent by 

 Phillips to Berkeley, I observed a few free spores correspond- 

 ing in size with the spores of the present species, but 

 minutely papillose ; all the spores, however, that were in 

 the asci, and therefore certainly belonging to this species, 

 were perfectly smooth, and even if it is eventually shown 

 that the spores become ornamented, yet the species will be 

 readily distinguished by the very large, hexagonal cells of 

 the excipulum.
