(or can't go far from home for a while) you can always move on to looking at fungi which parasitise bryophytes! There is now an outstanding new reference website for these things http://www.octospora.de/, including a list of bryophyte hosts (http://www.octospora.de/HostParasite.htm) and lots of info, descriptions and photos. Octospora grimmiae on Grimmia pulvinata should be worth a look, as should Neotiella ricciae on Riccia spp. What fun, with lots of spore squashes to enjoy!!
