BOTANY 



LICHENS (Ucbeni) 



Our knowledge of the lichens of Berkshire is in an even more 

 elementary stage than that of the fungi. Beyond a few species collected 

 by Mr. Baxter, Mr. E. M. Holmes and myself, and those mentioned in 

 Leighton's Lichen Flora of Great Britain, scarcely anything is known. 



Collema crispa. Windsor Great Park 



nigrescens 



fascicularis 

 Baeomyces roseus. Bagley 

 Cladonia gracilis. Wokingham 

 Usnea plicata 



articulata. Bagley 

 Ramalina fastigiata 

 Sticta pulmonaria 

 Thelotrema lepadinum 



Physcia pulverulenta var. subvenusta. 

 Windsor Great Park 



parietina f. cinerascens 



lychnea. Windsor 



ciliaris. FaringJon, Windsor 

 Parmularia nigra 



Pannaria nigra 



psotina 



Lecanora murorum var. corticola 



laciniosa 



vitellina sub-sp. xanthostigma 



Lecanora aurantiaca 



luteo alba 



phlogina 



irrubata 



allophana 



Hageni 



orosthea 



var. sublivescens 

 Lecidea alboatra var. epipolia 



caradocensis 



myriocarpa 

 Opegrapha lyncea 



atra 



varia 



Graphis inusta f. macularis. Windsor 



elegans 

 Verrucaria rupestris 



cinerea 



nitida 



mutabilis. Bagley 



Among special localities are the old walls of coralline oolite and 

 the damp heaths of the Bagshot sands, as well as the trees of the 

 extensive woodlands of the Kennet valley. 



FUNGI 



The very varied character of the soil of Berkshire afford a rich 

 gathering of fungi ; and an autumnal walk through the extensive woods 

 such as border the Kennet valley or those of Wytham and Bagley in the 

 north, or the park of Bearwood and the chalk woods of Bisham and 

 the great park of Windsor, will reward the student of this perishable 

 order of plants a very numerous gathering. But it must be confessed 

 that the information about the Berkshire fungi is very scanty, and that 

 much remains to be done to bring the knowledge of their distribution to 

 any degree of completeness. 



Mr. Baxter made a close investigation of the microscopic forms in 

 the neighbourhood of Oxford. Bagley Wood proved a specially rich 

 locality, and in his published set of dried specimens many of these 

 species came from this and other localities on the Berkshire side of the 

 Thames. 



Both Miss Beatrice Taylor and I collected many species from the 

 Boar's Hill range, and I have seen how rich some parts of the Kennet and 

 Loddon districts are.
