LETTER FROM THE PRESIDENT

Dear Shareholder:

We  are  pleased  to  present  this  semiannual  report  for  Dreyfus California
Tax-Exempt  Money  Market Fund, covering the six-month period from April 1, 1999
through  September  30, 1999. Inside, you'll find valuable information about how
the  fund  was  managed during the reporting period, including a discussion with
the    fund'   s    portfolio    manager,    Jill    Shaffro.

When  the  reporting  period  began,  investors had become concerned that strong
economic  growth  in  the  United  States  might  rekindle  dormant inflationary
pressures.  As  a  result,  after  remaining  relatively steady during the first
quarter  of  1999,  yields on money market securities rose during the second and
third  quarters in response to expectations that the Federal Reserve Board might
raise short-term interest rates. In fact, the Federal Reserve Board raised rates
twice  during  the  summer  of  1999  in  an  attempt  to  forestall a potential
resurgence of inflationary pressures. This increase effectively reversed most of
last  fall' s  interest-rate cuts, and led to higher yields on most money market
securities.

Tax-exempt  money  market  yields  were  also  influenced  by  supply-and-demand
factors.  Strong economic conditions have curtailed many municipalities' need to
borrow  over  the  short term, reducing the available supply of tax-exempt money
market  securities. Yet investor demand remained strong from individuals seeking
to  minimize  their tax liabilities. This imbalance helped constrain the rise of
tax-exempt  money  market  yields relative to taxable money market yields during
the first nine months of 1999.

We  appreciate  your confidence over the past six months, and we look forward to
your continued participation in Dreyfus California Tax-Exempt Money Market Fund

Sincerely,


Stephen E. Canter
President and Chief Investment Officer
The Dreyfus Corporation

DISCUSSION OF FUND PERFORMANCE

Jill Shaffro, Portfolio Manager

How did Dreyfus California Tax-Exempt Money Market Fund perform during the
period?

For  the  six-month  period  ended  September  30,  1999,  the  fund  produced a
tax-exempt  yield  of 2.36%. Taking into account the effects of compounding, the
fund  provided  an effective yield of 2.38%.(1) The fund produced a total return
of  1.19% (2)  compared  to  the Lipper California Tax-Exempt Money Market Funds
category  average  return  of  1.21%  over  the same period.(3) We attribute the
fund' s performance to lower short-term interest rates, which were the result of
changes in monetary policy as well as supply-and-demand factors.

What is the fund's investment approach?

The  fund' s  objective  is to seek a high level of federal and California state
tax-exempt  income  while  maintaining  a  stable  $1.00  share  price.  We  are
especially    vigilant    in    our    efforts    to    preserve    capital.

In  pursuing this objective, we employ two primary strategies. First, we attempt
to  add  value  by  constructing  a diverse portfolio of high-quality tax-exempt
money market instruments from California issuers. Second, we actively manage the
fund'  s   average   maturity   in  anticipation  of  interest-rate  trends  and
supply-and-demand changes in the short-term municipal marketplace.

For example, if we expect an increase in short-term supply as California and its
municipalities  currently  issue  short-term  debt,  we may decrease the average
maturity of the fund to enable it to purchase new securities with higher yields.
That' s  because  yields tend to rise if many issuers are competing for investor
interest.  New  securities  are generally issued with maturities in the one-year
range,  which  tend to lengthen the fund's average maturity. If we expect demand
to  surge  at  a  time  when we anticipate little issuance and, therefore, lower
yields,  we  may  increase  the portfolio's average maturity to maintain current
                                                              The Fund


DISCUSSION OF FUND PERFORMANCE (CONTINUED)

yields  for  as long as practical. At other times, we try to maintain an average
maturity  that  reflects  our view of short-term interest-rate trends and future
supply-and-demand considerations.

 What other factors influenced the fund's performance?

The  fund  was  affected  by  rising  interest  rates  over the past six months.
Economies  in  Japan and Southeast Asia appear to have begun to recover, and the
growth  of  the U.S. economy has been stronger than most analysts expected. This
economic   news   raised   concerns   among  some  fixed-income  investors  that
inflationary  pressures  might  re-emerge.  In  fact,  the Federal Reserve Board
increased  short-term  interest  rates  twice  during  the  summer of 1999 in an
attempt   to  forestall  a  reacceleration  of  inflation.  Because  the  market
anticipated  these changes in monetary policy before they were announced, longer
term  tax-exempt  yields  had  already risen by the time the interest-rate hikes
were actually implemented.

However,  tax-exempt  money  market  yields  did  not rise as much as comparable
taxable  yields, primarily because many states and municipalities throughout the
country  -- including California -- have enjoyed higher tax revenues during this
period  of  economic  prosperity.  As  a result, many of California's government
entities  have  had  little  need to borrow in order to satisfy their short-term
obligations.  The  relative  lack  of  supply amid steady investor demand helped
constrain the rise of short-term tax-exempt yields.

What is the fund's current strategy?

We  have continued to focus on very high-quality liquid money market instruments
from  a  wide  array  of  California  issuers.  Some of the most frequently used
instruments  include  Variable  Rate  Demand  Notes (VRDNs), which are issued by
investment  banks  through  the  securitization  of longer term municipal bonds.
Because  VRDNs  can  be  redeemed  at the buyer's option after either one day or
seven  days,  they  afford  the  fund a high degree of liquidity as well as high
credit quality.  Accordingly, as of September 30, much of the portfolio was
composed of VRDNs.  The remainder was comprised primarily of tax-exempt
commercial paper and tax-exempt notes. Of course, portfolio composition will
change over time.

We took advantage of new issuance of tax-exempt notes in June, which effectively
extended  the  fund's average maturity to the long end of the neutral range. The
addition  of notes also enabled us to lock in prevailing yields. Since June, new
purchases have been concentrated mostly in short-term commercial paper, which we
have  used to replace notes that matured or were redeemed by their issuers. This
strategy has resulted in a gradual decrease in the fund's average maturity to 62
days  as  of September 30. We believe that this position will help us retain the
flexibility  we  need  to capture high current yields while remaining capable of
responding quickly to changing market conditions.

NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1--Significant Accounting Policies:

Dreyfus California Tax Exempt Money Market Fund (the "fund") is registered under
the  Investment  Company  Act  of 1940, as amended (the "Act"), as a diversified
open-end  management  investment  company. The fund's investment objective is to
provide investors with as high a level of current income exempt from Federal and
State  of  California  income  taxes  as  is consistent with the preservation of
capital   and  the  maintenance  of  liquidity.  The  Dreyfus  Corporation  (the
" Manager" ) serves  as  the  fund's investment adviser. The Manager is a direct
subsidiary  of  Mellon  Bank,  N.A.  Premier  Mutual  Fund Services, Inc. is the
distributor  of  the fund's shares, which are sold to the public without a sales
charge.

It  is  the  fund's policy to maintain a continuous net asset value per share of
$1.00; the fund has adopted certain investment, portfolio valuation and dividend
and distribution policies to enable it to do so. There is no assurance, however,
that  the  fund  will  be able to maintain a stable net asset value per share of
$1.00.

The  fund' s  financial  statements  are  prepared  in accordance with generally
accepted  accounting  principles,  which require the use of management estimates
and assumptions. Actual results could differ from those estimates.

(a) Portfolio valuation: Investments in securities are valued at amortized cost,
which  has been determined by the fund's Board of Trustees to represent the fair
value of the fund's investments.

(b)  Securities  transactions and investment income: Securities transactions are
recorded  on  a  trade date basis. Interest income, adjusted for amortization of
premiums  and original issue discounts on investments, is earned from settlement
date and recognized on the accrual basis. Realized gain and loss from securities
transactions  are  recorded  on  the  identified cost basis. Cost of investments
represents  amortized  cost.  Under the terms of the custody agreement, the fund
received net earnings credits of $2,963 based on available cash balances left on
deposit. Income earned under this arrangement is included in interest income.


The  fund  follows  an  investment  policy  of  investing primarily in municipal
obligations  of  one  state. Economic changes affecting the state and certain of
its  public  bodies  and municipalities may affect the ability of issuers within
the  state to pay interest on, or repay principal of, municipal obligations held
by the fund.

(c) Dividends to shareholders: It is the policy of the fund to declare dividends
daily  from  investment  income-net.  Such dividends are paid monthly. Dividends
from  net realized capital gain are normally declared and paid annually, but the
fund  may  make  distributions  on  a  more  frequent  basis  to comply with the
distribution  requirements of the Internal Revenue Code of 1986, as amended (the
" Code" ). To the extent that net realized capital gain can be offset by capital
loss carryovers, it is the policy of the fund not to distribute such gain.

(d) Federal income taxes: It is the policy of the fund to continue to qualify as
a  regulated  investment  company, which can distribute tax exempt dividends, by
complying  with the applicable provisions of the Code, and to make distributions
of  income  and  net  realized  capital  gain  sufficient  to  relieve  it  from
substantially all Federal income and excise taxes.

The  fund  has  an  unused  capital  loss  carryover  of  approximately $101,000
available  for  Federal  income  tax  purposes  to be applied against future net
securities  profits,  if  any,  realized  subsequent  to  March 31, 1999. If not
applied,  $38,000  of  the  carryover expires in fiscal 2000, $21,000 expires in
fiscal  2002, $27,000 expires in fiscal 2003, $10,000 expires in fiscal 2004 and
$5,000 expires in fiscal 2005.

At  September  30, 1999, the cost of investments for Federal income tax purposes
was substantially the same as the cost for financial reporting purposes (see the
Statement of Investments).

NOTE 2--Management Fee and Other Transactions With Affiliates:

(a)  Pursuant  to a management agreement with the Manager, the management fee is
computed  at  the  annual  rate  of .50 of 1% of the value of the fund's average
daily net assets and is payable monthly.

                                                             The Fund

NOTES TO FINANCIAL STATEMENTS (Unaudited) (CONTINUED)

(b)  Under  the  Shareholder  Services Plan, the fund reimburses Dreyfus Service
Corporation,  a  wholly-owned subsidiary of the Manager, an amount not to exceed
an  annual rate of .25 of 1% of the value of the fund's average daily net assets
for certain allocated expenses of providing personal services and/or maintaining
shareholder  accounts.  The  services  provided  may  include  personal services
relating  to  shareholder  accounts,  such  as  answering  shareholder inquiries
regarding  the  fund  and  providing reports and other information, and services
related  to  the  maintenance  of  shareholder accounts. During the period ended
September  30,  1999,  the  fund was charged $57,509 pursuant to the Shareholder
Services Plan.

The  fund  compensates  Dreyfus Transfer, Inc., a wholly-owned subsidiary of the
Manager,   under  a  transfer  agency  agreement  for  providing  personnel  and
facilities  to  perform transfer agency services for the fund. During the period
ended  September 30, 1999, the fund was charged $25,691 pursuant to the transfer
agency agreement.

(c)  Each  trustee  who  is  not  an  "affiliated  person" as defined in the Act
receives from the fund an annual fee of $2,500 and an attendance fee of $250 per
meeting.  The  Chairman  of  the  Board  receives  an  additional  25%  of  such
compensation.
