H The star’d spores are stated to be 2-guttulate. 
! The spore dimensions varying from 5-6 by 1-14 mw in cudmna 
to 8-14 x 2-3°5m in canella Karst. The dimensions of the asci are 
also extremely variable, ranging from 25-35 by 4-5 m in luteola, to 
60 by 10-12 win macrosperma. We cannot conceive of variation to 
this extent coming under one species, either as forms or varieties. 
Without any desire to increase the number of species by any 
hair-splitting policy, it may be that several of the 12 forms 
deserve specific rank. Dr. Rehm in Rabhn. Krypt Flora 
Albthung III. p. 525, has given this to minutella, and placed 
epilobit Kunze under it as a synonym. 
We do not think species with 2 guttulate spores should be 
placed here. If spore characters have to count for anything 
Leptospora, 13-14 by 2m, and eguttulate, cannot possibly be 
classed with culmina spores 5-6 by 1-14mand 2 guttulate. So 
with others. Five of the twelve are stated to have 2 guttulate 
spores. Independent of variability in size, we do not consider 
any form having gutte in its ‘spores should come under the 
common cznerea. 
In well known species, (not particularly Mollisiz), that have 
guttulate spores, the guttz are constant, and vice-versa so that 
it is not safe to unite under one species, those having guttulate, 
with those that have eguttulate spores. Characters that can be 
proved to be constant, and are distinct from those pertaining to 
other species, must count for something in the summing’ up, of 
what we understand as specific differences. Batsch’s species was 
found on wood and Saccardo placed it in his Ligni corticola 
section all right yet four only of the 12 sub-pended forms, ZuteoZa, 
olivescens, macrosperma and canella, are stated to grow on 
wood, while the remaining 8 are on herbaceous stems. _
