Though the asci and spores in our specimens are rather 

 smaller than in Rehm's, I have no doubt as to the identity of 

 the species. Rehm's asci are 50-60 x 9-10 /x and spores 9-12 x 3 /x; 

 Saccardo gives them as 56 x 8 /x and 8-10 x 3 /x respectively. In 

 the Hebden Bridge specimens the asci are 40-45 x 6-7 /x and 

 spores 8-10 x 2 '5 jx, occasionally approaching 3 /x.

The ascophores are almost wholly immersed in the matrix, 

 very little more than the margin and disc being visible above 

 the surface ; the ripe extruded asci are very prominent before 

 shooting ' off their spores. The spore dimensions ' as given in 

 Sacc. Syll. are 25 x 14 ja. M. Boudier considers them to be 

 30-35 /x long. My measurements are 28-30 x 14 /x. Mr. Massee 

 has kindly compared the Halifax material with that from 

 Spegazzini in the Royal Herbarium, Kew, and considers them 

 identical.

The spores of this species are amongst the smallest met 

 with in the genus Ascobolus ; in Boudier's specimens they were 

 13-15x7-9 fx, in ours 1 1-14 + 6*5-7 "5 /x. The asci are com- 

 paratively slender for that family, 140-170x13-14 Bond., ours 

 140-160 x 12-13 5 as a consequence the spores remain uniseriate 

 until ejected, which is unusual in Ascobolus.

This differs from H. maxima, a British species, in the much 

 smaller spores and longer ostiolum. H. Serignanensis is only 

 previously recorded from France, occurring on a similar matrix.

The following observations were taken while examining the 

 mould : — Tufts minute, separate or confluent, brick-red to ver- 

 milion, fertile hyphae erect or spreading, lax or intricately 

 compact in the mass, sparingly and irregularly branched, 

 straight or slightly wavy, paler than the conidia, 100-140 /x long 

 by 4-6 /x thick below, thicker and somewhat moniliform above 

 preparatory to the formation of conidia ; conidia plentiful, con-
