FUNGI IMPERFECT I 



[a) Aleuriospore, smooth, small, acro-pleurogenous : — 



1. Aleuriospores coloured — Aleurisma Link, 1809. 



2. Aleuriospores pale — Corethropsis Corda, 1839. 

 {b) Aleuriospore, large, spiny, acrogenous: — 



1 . Aleuriospore appendiculate — Mycogone Link, 1 809. 



2. Aleuriospore non-appendiculate — SepedoniumlAn^, 1809, 



B. HyphcB dark : — 



I. Hyphae pale and dark. Aleuriospores become dark and acro- 

 pleurogenous on light or dark hyphae, small, generally 6X4, 

 rarely iiX 5 microns — Glenospora Berkeley and Curtis, 1876. 

 II. Hyphae very dark. Aleuriospores remain hyaline, situate acro- 

 genously on hyaline hyphae at the base of sterile ■ dark 

 hyphae, large 11-14 microns — Botryotrichum Saccardo and 

 Marchal, 1885. 



Genus Acladium Link, 1809. 



Definition. — ^Aleurismese with pale elongate hyphae and with 

 sporogenous apparatus, but little differentiated from the mycelium. 

 Sporophores unbranched. Conidia pleurogenous. 



Type Species. — Acladium conspersunt Link, 1809. 



Remarks.- — There is only one species which concerns us- — viz., 

 A. castellanii 



Acladium castellanii Pinoy, 1916. 



Definition. — Acladium with small chains of acrogenously placed 

 chlamydospores. The aleuriospores are acropleurogenous. 



Remarks. — The parasite was found byCastellani in cases of ulcera- 

 tive dermatitis, with gumma-like nodules, inT.eylon, the Federated 

 Malay States,, and Macedonia, and fully described by Pinoy.

 Potato and Carrot. 



The growth on artificial media (such as carrot, potato, glucose 

 agar) consists of many small roundish masses, which later on may 

 coalesce. They are covered by spiculated formations, giving them a
