the Fungi of Austin, Texas, and Vicinity 583 



They form a distinct group, having few or no species in common 

 with the other geographical groups. Several of the Lycoperdales 

 are found here, also a large Sarcospliaera with an oil drop in the 

 center of its hyaline spore. In this group comes a Helvetia with 

 spores like those of Sarcospliaera ; a large Morchella nearly one 

 foot tall, with pileus the color and texture of beeswax ; and two 

 species of Lepiota with perfectly smooth pilei. 



In Group III are those found under the post oaks (Quercus 

 minor) and black jacks (Q. Marilandicd), generally in sandy, 

 gravelly soil, or in the debris of leaves that the winds have col- 

 lected into heaps, often one foot deep and several yards wide. 

 Here is a totally different fungal vegetation. Not a species has 

 been found in this habitat that is common to the other groups. 

 Here the volvate and annulate species of Agaricales flourish, also 

 several large fleshy species with bright colored pilei. In the leaf 

 debris mentioned, several species of Boletus are found. These are 

 all, without exception, Spring fungi. 



Group IV includes those growing in grassy places, on lawns, 

 etc., where the ground is frequently watered and the turf perma- 

 nent. The Phallales are prominent members of this group, es- 

 pecially Phallus rubicimdus, which was found in several widely sepa- 

 rated localities, each time in lawns, open and unshaded. One yard 

 especially had them in great abundance ; at least one hundred 

 specimens were collected in various stages of development, from 

 the hyphae just forming a weft, to the mature and deliquescing 

 plant. The parties living at this place said the fungus had ap- 

 peared in their yard every year during the last ten years. All the 

 specimens were found during April and May ; none appeared from 

 % May to September, probably because exceedingly hot dry weather 

 has prevailed since then. Two specimens of Simblum rube scats 

 were found close together, on a partially shaded lawn ; this is much 

 rarer here than P. rttbicwidus, as the two specimens were all that 

 have been found after careful and continued search during the en- 

 tire spring, which has been exceedingly rainy and wet, and there- 

 fore unusually favorable to fungal growths of every description ; 

 many fungi have undoubtedly been collected during this season 

 that will probably not be seen again in years. 



Group V contains the epixylous species, the wood being in
