Tricholoma virgatum Fr. P|. 167, is I believe from a figure of min

This is a very common fungus amongst short grass especially 
road sides, but itis one over which we all came to grief and it

In Fries “ Hymenomycetes” the sub-division Disciformes of 
Clitocybe is split up into five groups: in the fourth of which 
rivulosa is placed. This group is characterized as “ Pileo vi 
pallescente,” now it so happens that C/. rizvulosa has no trace 
green about it anywhere. ‘The subsequent writers (Stevenso 
Cooke and Massee) have simply copied and re-copied the err 
hence in our attempts to make out the fungus from 
English handbooks we have always passed over the group whit 
contained the description of C/. rivulosa. Various names _ hat 
been suggested for the plant in question—e. g. 4. dealbatt 
gallinaceus, obsoletus, diatretus, &%c., but there is no doubt that 
rivulosa is the fungus Fries originally had in view. It is a smé 
whitish species which in wet weather looks as if it had a coat | 
white varnish and it is the cracking of this coat in a rivulo 
manner which gives the fungus its name. When growing al 
well grown it has a very pale flesh coloured tint, but this is n 
observable on every specimen: with age it becomes light | 
colour and distorted in form. [Iam by no means sure that Huss
