BROOKES, DR. ANNA, Brazil (f): 



Hirneola polytricha. Polyporus subolivaceus. Polystictus occidentalis 

 (thin form). Polystictus rigens. Polyporus zonalis. Polyporus varius. 

 Lentinus blepharodes (cfr. under Fischer, Letter No. 34). Polyporus. I 

 think zonalis, abnormal development, but I am not sure. Stereum (Hymeno- 

 chaete.) 



Polyporus (Amaurodermus) Brockesii. Pileus thin, depressed in 

 center, subinfundibuliform. Surface smooth, reddish brown, with darker 

 zones. Stipe mesopodial, slender, with dull velutinate surface. Pores large, 

 y 2 -l mm. shallow, dark yellow, with concolorous mouths. Setae none. 

 Spores abundant, colored, elliptical, smooth, not apiculate, 10 x 16 mic., with 

 large guttae. A single specimen from Dr. Anna Brockes, Crixas, Brazil. 

 This plant I would class in the section 7a of the recent Stipitate 

 Polyporoids, with Polystictus gracilis, from which it differs in spores and 

 stipe insertion. In general appearance and color it is close to Polyporus 

 rufobadius, and the illustration (Bull. Soc. Myc. France, Vol. 5, pi. 10) 

 well represents it in general appearance. Polyporus rufobadius (which 

 I think is probably same as omphalodes) has minute pores and globose 

 spores. 



Polyporus rheicolor. These are the first specimens I have received, 

 although it is found in several museums of Europe under three (and prob- 

 ably four) different names, Polyporus Splitgerberi (good type at Leiden, 

 scanty at Paris, Kew and Upsala), Polyporus sulphuratus (types at Upsala 

 and Kew), and Polyporus rheicolor (type at Kew and Paris). In addition, 

 Polyporus citreus (very poor type from Australia at Kew) may be the 

 same. It is the only thin species I know with bright yellow context and 

 deep-colored spores. This is the first entire specimen I have seen, and the 

 specimen is submerismatoid in manner of growth. Nothing can be told 

 of its usual manner of growth from the separate pileoli in the museums. 

 From Rick's collection at Paris I had the impression it was imbricate. Of 

 the various names given the plant rheicolor is the best. With the exception 

 of citreus (which is doubtfully the same) all the collections in the museums 

 are from tropical America. 



Xylaria aristata. Lachnocladium brasiliense. Stereum (Section 

 Lloydiella). Stereum (Section Lloydiella). Polyporus gilvus? 



CAHN, MRS. J. A., Michigan: 



Polystictus hirsutus. Polystictus hirsutus (thin form). Hydnum 

 ochraceum. Polystictus circinatus (a rather rare find). Lenzites betulina. 

 Polyporus dichrous. Stereum versicolor (=S. fasciatum Schw.). Poly- 

 porus gilvus. Daedalea confragosa (trametoid form). Polyporus melan- 

 opus. Tremella frondosa. Polyporus versicolor, old specimen, the 

 hymenium colored red by some parasitic species. Polyporus (not sure as 

 to the species). Polyporus albellus. Favolus europaeus (small pored form 

 =Favolus microporus). Stereum spadiceum (when fresh the hymenium 

 turns red on bruising). Favolus europaeus (type form). Lenzites trabea 

 (=L vialis). Polyporus adustus. Polystictus hirsutus (abnormal as to 

 shape). Daedalea unicolor. 



CASTILLON, LEON., Argentine (g): 



Schizophyllum commune. Polyporus rhipidium var. pusillum.
