LETTER No 39 



FUNGI OF MADAGASCAR. 



We have received from Monsieur Henri Perrier de le Bathie, 

 Madagascar, a very fine collection of fungi that we think worthy of a 

 separate letter. The collection embraces more specimens than we have 

 noted in the museums of Europe and we presume more than has here- 

 tofore been sent in from Madagascar. It includes two striking novel- 

 ties, namely: Fomes perlevis and Fomes sculpturatus. I would deter- 

 mine the plants as follows: 



Hirneola polytricha. This'in my opinion, is only the tropical form 

 for the ' 'Jew's ear' ' Hirneola auricula - Judae of the temperate world. 



Cyclomyces fuscus. Peculiar plant with concentric gills. Cfr. 

 Myc. Notes No. 36, page 487. 



Hexagona mirabilis. I recently received this plant from Mr. 

 O'Connor, Mauritius, but otherwise it is only known to me from the 

 original station Samoa. 



Polystictus affinis. Perfectly smooth and in color approaching 

 carneo-niger. 



Trametes hystrix. Common and only occurs in Africa. Close to 

 Trametes hydnoides of the American tropics but has constantly larger 

 pores. However, many specimens of it are in the museums, misnamed 

 Trametes hydnoides (which does not occur in Africa). 



Polystictus vinosus. Readily known by its peculiar vinous (atro- 

 purpureus) color. 



Polyporus sacer. (Cfr. Stipitate Polyporoids page 122, fig. 420). 

 A peculiar African species only. 



Polystictus Persoonii (form rubriporis) without question a form 

 of Polystictus Persoonii, with the (red) pore mouths concolorous with 

 the pileus. I have seen many collections of this tropical species but 

 never before one that did not have white pore mouths. The context 

 of this collection is white as ordinary. 



Polystictus leoninus. (Cfr. Synopsis Funalis page 64). A pecu- 

 liar and common plant in the East and Africa. 



Polystictus sanguineus. The common red species of the tropi- 

 cal world. 



Lenzites repanda, also common throughout the tropical world.
